24-May-12 Section 1. Introduction

EntelliGuard G circuit breakers are the newest line of low voltage power circuit breakers (LVPCBs) evolved from the exceptional designs and practices of GE legacy breakers. EntelliGuard G breakers offer a truly global product platform that meets industry standards throughout the Americas, Europe and Asia (ANSI, UL, CSA, IEC, Lloyds Register of Shipping, etc.).

Breakers are available to OEMs in 3- and 4-pole designs from 400A to 6400A (IEC) with fault interruption ratings up to 150kA. New, state-of-the-art EntelliGuard Trip Units enable the breakers with advanced technology that provides system protection, local and remote monitoring, relaying and communications. EntelliGuard Trip Units may be supplied with either Modbus or Profibus communications protocols. The breaker-trip unit system delivers superior circuit protection without compromising selectivity or arc flash protection. The EntelliGuard system is yet another evolution of GE’s core competencies in reliable electric power distribution, circuit protection and arc flash protection.

EntelliGuard G 3-pole breakers are the standard in GE AKD-20 Low Voltage Switchgear. The breakers are suitable for 280Vac, 480Vac and 600Vac applications, and they provide advanced circuit protection, limit arc fault energy and preserve system coordination without sacrificing any of these critical functions (Table 1.1).

UL489B DC for

IEC 60947-3 IEC 68-2-52 Level 2: salt mist

CSA 22.2 NO 5.1

EntelliGuard G devices are available in all standard, 100% rated, ANSI, UL and IEC ratings in both fixed and draw-out designs. Standard devices are also offered in 4 pole designs. No compromise (e.g., derating) is necessary in the system protection scheme as the EntelliGuard G Neutral poles are fully rated. Front and rear access connections are available, and all configurations can be manually or electrically operated with multiple and redundant accessories (optional) (Table 1.2).

EntelliGuard G short circuit and interrupting ratings are given in Tables 1.3 through 1.6.

EntelliGuard G Power Circuit Breaker Section 3. EntelliGuard TU Trip Unit System

Introduction

Reliability without Compromising Protection

Arc Flash and the EntelliGuard TU Trip Unit

24-May-12 Section 3. EntelliGuard TU Trip Unit System

The EntelliGuard TU Trip Unit offers optimum circuit protection and optimum system reliability simultaneously with little or no compromise to either of these critical functions. Reliability and arc flash protection, in one package, at the same time, all the time.

EntelliGuard TU series trip units are available as the standard controller for new production EntelliGuard G ANSI/UL 1066, UL 489 and IEC circuit breakers. EntelliGuard TU designs are also available as direct, functional replacements for GE's PowerBreak, PowerBreak II, WavePro, AKR, and AK circuit breakers. EntelliGuard TU trip units are also available in kit form for many popular non-GE and older GE low voltage power circuit breakers (Refer to DEH-4567). The EntelliGuard® TU technology is also available in GE's molded case Spectra Breaker line 400A-1200A. The Spectra MET (microEntelliGuard) includes the innovative RELT and Zone Selective Interlocking- Instantaneous feature. New, onboard features and communications capabilities enable equipment enhancements, improved operational performance and life extension programs. Performance will vary based on associated circuit breaker and equipment conditions. All EntelliGuard TU Trip Units are Conformal Coated for increased reliability in humid/damp environments.

This section describes the functions as implemented in the EntelliGuard G UL 489 and ANSI/UL 1066 circuit breakers. References or comparisons to other GE circuit breakers are for informational purposes only.

Reliable protection of circuits and equipment has always been the circuit breaker’s primary mission. Providing appropriate protection of the conductors, while preserving selective coordination, has been the primary focus of most system designers. However, what was acceptable in the past is no longer the standard today.

Modern economic reality, coupled with strict regulatory requirements, demand optimal system performance with increased sensitivity to the inherent power system hazards that face operating and maintenance personnel. Safety agencies, local authorities and owner-operators demand better personnel protection and state-of-the-art capabilities to minimize hazards while simultaneously preserving critical loads and system capabilities.

These requirements often seem to be, and sometimes are, in conflict, pitting the speed and sensitivity required to improve arc flash protection against the delays and deliberate decision making required to maximize power system reliability. The EntelliGuard TU, along with the EntelliGuard family of circuit breakers, offers flexible solutions for demanding circuit protection and circuit preservation environments. The EntelliGuard TU is designed to provide the utmost in system protection and reliability simultaneously, with little or no compromise.

Reducing arc flash hazard is a primary concern in many power system designs. The best way to ensure the lowest possible hazard for a particular distribution system is to consider the hazard as the system is designed and make careful selection of the system’s topology, circuit sizes, equipment sizes and protective devices to minimize hazard for the operating and maintenance personnel that will need to use the system for years to come.

The EntelliGuard TU, especially in conjunction with the EntelliGuard G circuit breaker, provides significant flexibility towards solving arc flash hazard problems without excessive sacrifice of system reliability, in terms of selectivity.

The next three to four pages are an overview of the EntelliGuard TU's unique features enabling Arc Flash mitigation and selectivity at the same time. When the downstream breaker/fuse is current limiting, the Waveform Recognition Selective Instantaneous is used to achieve lower Instantaneous pickup settings while maintaining selectivity. This is very effective for 250A and below devices. For Feeder devices above 250A, the Instantaneous Zone Selective Interlocking (I-ZSI) feature is used to achieve selectivity and arc flash mitigation at the same time. The I-ZSI feature is available on Spectra MET and EntelliGuard® TU in the following breakers: EntelliGuard G, Power Break II, WavePro, AK/AKR, and Conversion Kits. By combining the Waveform Recognition Selective Instantaneous and I-ZSI, a system with a 100KAIC bolted fault current can achieve a 8 cal/cm2 or less incident energy level.

One way to lower potential incident energy is to ensure that circuit breakers are able to interrupt using their Instantaneous trips for all expected arcing faults. Figure 3.1 shows the expected arcing currents for 480V systems for various arc gaps representative of switchgear (32mm), switchboards (25mm), MCCs (25mm) and panelboards (13mm). These values were determined using IEEE standard 1548, Guide for Performing Arc-Flash Hazard Calculations,

2002.

TU Trip Unit System

Figure 3.1 demonstrates the wide range of possible arcing currents predicted by the IEEE standard’s calculations. The actual arcing currents may be lower or higher when consideration is given to the potential error in short circuit calculations, fault current data provided by the utility company, and variance in the actual arcing gap or enclosure’s geometry where the arc occurs. Of particular concern should be the lower end of the possible range of current that may fall below the Instantaneous pickup of a circuit breaker or the current limiting threshold of a fuse. Dangerous incident energy may quickly increase when interruption time increases from a few cycles to a few seconds, even for low arcing current.

The EntelliGuard TU trip unit’s Waveform Recognition Selective Instantaneous provides a unique selectivity capability. When used in conjunction with current limiting devices downstream, the trip unit may be set low, and still maintain significant levels of selectivity. Table 3.1 lists the minimum instantaneous setting above specific GE circuit breakers and the levels of selectivity achieved. Testing and documentation of the selectivity capability of the EntelliGuard Trip unit will be expanded as more test data becomes available. Always consult GE Selectivity reference publication DET-537 for the latest information or contact your GE sales representative for up to date information.

Selectivity above current limiting fuses may also be expected. The required minimum setting may be estimated by examining the peak let-through curve for the fuse. Find the peak let-through current value that is 1.41 times the prospective RMS current. The trip unit should be set such that the instantaneous pickup is above that peak value. The

circuit breaker and fuse may then be selective up to the values identified in Table 3.1. The fuse and circuit breaker combinations have not been tested so performance cannot be guaranteed at this time; however, selectivity is expected for arcing and bolted faults up to the values indicated in the above selectivity table.

Protection between circuit breakers using the EntelliGuard TU trip unit may be further improved using zone selective interlocking. The trip unit’s unique instantaneous zone selective interlocking which can increase selectivity for UL 489 EntelliGuard G mains while allowing to trip instantaneously for faults within their zone of protection allows significant selectivity and arc flash protection at the same time.

Selectivity for an EntelliGuard TU ground fault function and a circuit breaker below may be enhanced by the trip unit’s selective ground fault function and zone selective interlocking. Figure 3.2 demonstrates an 800A circuit breaker under a 1200A ground fault set to be fully selective. See also Tables 3.2 and 3.3.

24-May-12 Section 3. EntelliGuard TU Trip Unit System

Selectivity between any line side (main)Circuit Breaker with a GE EntelliGuard TU trip unit and a load side (branch) GE current limiting circuit breaker, and certain lighting panel type circuit breakers is determined based on the setting of the line side EntelliGuard TU Trip. When the line side EntelliGuard TU Trip unit is set at the value defined in the table or higher the pair is selective over the instantaneous range of the upstream CB up to the limit defined in the table below. The required settings are independent of the line side circuit breaker type and only depend on the load side current limiting circuit breaker. The table below identifies the values for GE's currently produced UL listed current limiting molded case circuit breakers.

Extent of selectivity will depend on line side circuit breaker type. The table below describes how that selectivity is limited by circuit breaker type.

The table below applies at 208 through 480 Volts except where specifically limited to 240V and lower.

TU Trip Unit System

• Instantaneous selectivity between a circuit breaker with an EntelliGuard TU trip Unit and any non-current limiting circuit breaker may be evaluated via

traditional time current curve analysis or simply multiplying the upstream instantaneous trip setting by .9 which accounts for the tolerance of the line side circuit breaker around the nominal setting. If The EntelliGuard TU's Instantaneous zone selective interlocking capability between similarly equipped circuit breakers is employed then selectivity up to the upstream circuit breaker's full withstand or short circuit rating is possible.

TU Trip Unit System

The EntelliGuard TU trip unit has Short Time bands under 100msec designed to optimally fit above the Instantaneous clearing times of various GE circuit breakers. Table 3.4 lists the suggested Short Time band that may be used above specific GE circuit breakers for the fastest coordination and consequently fastest EntelliGuard G circuit breaker interruption.

Also listed is the Hazard Risk Category for various available fault currents calculated at the listed Short Time band clearing times and Instantaneous clearing times provided by the EntelliGuard TU trip unit’s Waveform Recognition Selective Instantaneous and its Reduced Energy Let-Through (RELT) Instantaneous trip. The Hazard Risk Category (HRC) levels shown are calculated for a solidly grounded, 480V system, 32mm arc gap, 18 in. working distance and arc in box. Using the optimized Short Time band allows the system to stay at HRC2 most of the time and always less than HRC4. However, use of the RELT Instantaneous trip allows the system to protect at HRC1 or 2 for available fault currents as high as 90kA.

The Instantaneous algorithm in the EntelliGuard TU trip unit will allow a large switchboard or switchgear circuit breaker to be set low yet maintain selectivity. For example, when set to protect the conductors to a motor control center, an 800A feeder circuit breaker’s Instantaneous may be set as low as 8kA nominal. This should provide complete selectivity above the typical 150A and smaller circuit breakers or fuses found in a motor control center.

Allowing for 10% pickup tolerance in the Instantaneous pickup of the feeder circuit breaker would indicate that the feeder would pickup Instantaneously for arcing fault currents approximately 9kA or higher. From Figure 3.1 it can be seen that fault currents of 20-25kA and higher would seem to reliably produce arcing current above 9kA in a variety of configurations. From Table 3.4 it can be seen that an EntelliGuard G circuit breaker clearing instantaneously can maintain HRC1 in a system with up to 42kA available and HRC2 in systems with up to 100kA available – excellent arc flash protection and selectivity simultaneously!

Note: These incident energy calculations do not take into account motor contribution or other factors that may affect expected levels of incident energy or hazard. For a thorough understanding of the incident energy available or HRC in a power distribution system, an Arc Flash Study should be conducted by engineering personnel qualified to provide such analysis.

Using the EntelliGuard TU trip unit’s unique Instantaneous Zone Selective Interlocking (I-ZSI), the main circuit breaker also can be set to interrupt selectively for faults in its zone of protection. However, the pickup level must be nested to prevent a nuisance trip at the main. Allowing for a 10% tolerance in the pickup current of both trips, the upper boundary of the main’s trip may be estimated at approximately 11kA. Again, Figure 3.1 shows that available fault currents above 25kA will generally produce arcing currents above 11kA. Table 3.4 shows a system with fault currents from 35kA to 100kA, the feeder and main circuit breaker will provide protection at HRC1 or HRC2 selectively above most circuit breakers using short time bands. Coordinated instantaneous settings would provide even better protection while still maintaining selectivity with select feeder breakers. To this capability one can add the RELT instantaneous setting that provides more sensitive and faster protection when needed.

Trip plug rating in amperes. This is the current rating of the rating plug installed in the trip unit. This is the maximum Long Time pickup a trip unit can have with a specific plug installed. A sensor can usually be applied with plugs between 37.5% or 40% to 100% of the sensor rating. Plugs are labeled in amperes.

X is a multiplier that may be applied in front of any rating value to denote a fraction of that rating. Example: The Long Time Pickup may be set at 0.5X of In.

High Set Instantaneous Overcurrent, also known as the Override. This is an Instantaneous protection setting applied near the circuit breaker’s withstand rating required to clear high magnitude faults quickly. In UL489 circuit breakers this is fixed; in UL1066 CBs the override may vary, if present at all.

Making Current Release. A setting provided with each trip unit, based on the specific circuit breaker size, used to protect the circuit against closing on high magnitude faults. The MCR function immediately trips/opens the circuit breaker if high magnitude fault current is sensed at the instant the circuit breaker is closed.

Short Circuit Withstand Rating of a particular circuit breaker in amperes. The withstand rating is defined differently within different standards, but it is always the value of current that a circuit breaker can withstand for some period of time without interrupting.

Short Circuit Interrupting Rating (ISC), or ultimate interrupting rating (ICU) in IEC terms. The maximum shortcircuit interrupting rating of a circuit breaker in amperes.

TU Trip Unit System

The EntelliGuard TU offers two different shapes for Long Time protection curves. Each type of curve is available with 22 different time delays. The shapes may be described as

thermal type I

t characteristics and fuse shaped I4t lines. The nominal Long Time pickup is computed from the trip rating plug value (In) multiplied by the Long Time pickup setting. Long Time pickup setting multipliers are user settings and may range from 0.5 to 1.0 in increments of 0.05. The actual Long Time pickup is 112% of the nominal setting (Ir). 112% is to compensate for the Long Time Pickup Tolerance of ±10% that is drawing as “actual value/1+ tolerance)”. For a nominal 1000A Long Time pickup, the actual trip setting is 1120A, drawn as a vertical band between 1120/1.1 and 1120/0.9, or 1018A and 1244A.

The thermal I2t shape is similar to the typical curve of a thermal magnetic circuit breaker and matches the shape of many overcurrent devices used in industry today. The typical shape and range of settings may be seen in Figure 3.3. The range of time delays is shown in Table 3.5 at various multiples of nominal (100%) current setting. Drawn bands also include a mechanical constant time to account for circuit breaker operating and clearing time, which causes the slight widening of the band evident at the lower (right) end of the faster (lower) bands.

The Long Time and Short Time pickup algorithm also includes a cooling cycle that keeps track of current if it oscillates in and out of pickup range. This Thermal Memory is also active in case the circuit breaker trips on Long Time or Short Time to account for residual heating in conductors. If a circuit breaker is closed soon after a Long Time trip or Short Time trip, a subsequent trip may happen faster than indicated by the time current curve due to the residual cable Thermal Memory effect. In trips without control power, the Thermal Memory is powered from the Trip Unit battery. The cooling algorithm requires up to 14 minutes to fully reset to zero.

The EntelliGuard TU provides a wide range of Short Time

2

pickup settings, I

t characteristics and time bands to optimize selectivity while not sacrificing clearing time unnecessarily. Short Time pickup settings range from 1.5 to 12 times the Long Time pickup setting for the EntelliGuard G circuit breakers in Envelopes 1 and 2. The maximum Short Time pickup for Envelope 3 is 10 times. In Power Break, WavePro, AKR and other circuit breakers, the maximum Short Time pickup may be lower. The transition between Long Time band and Short Time function may happen at the horizontal Short Time Delay Band rather than the vertical Short Time pickup, depending on the following:

• How fast or what type of Long Time band is chosen

• What Short Time pickup is selected

• What Short Time Delay is selected

An example of this may be seen in Figure 3.5 for the combination of Long Time Delay Band and Short Time Delay Band shown in Figure 3.6, any Short Time pickup setting larger than 6X will result in the Long Time band intersecting with the horizontal Short Time delay band rather the vertical Short Time pickup.

The EntelliGuard TU comes with a wide range of adjustable Time Delay Bands, ranging from a minimum of 25ms (clears in 80ms, 55ms for Sensing, Operating and Clearing Time) to 417ms (clears in 472ms). The bands are specially designed to pickup above various circuit breakers and trip systems to provide required selectivity while not sacrificing any more clearing time than required to provide the best possible arc flash protection.

The time bands are shown in Table 3.6 and Figure 3.7.

The EntelliGuard TU trip unit offers the ultimate in Ground Fault protection. Each trip unit may be provided with the ability to accept a neutral sensor signal and generate an internal Zero Sequence phasor for Ground Fault protection. It may also be equipped with the ability to accept a Zero Sequence phasor signal from an external Zero Sequence CT or residual summation scheme using current transformers. Either Ground Fault method may be used to provide Ground Fault trip or Ground Fault alarm. Four pole circuit breakers may also provide Ground Fault protection based on an external Zero Sequence input signal or a residual sum of all four internal sensors.

The EntelliGuard TU trip unit uses internal air core sensors for current sensing, and the signals are residually summed using advanced digital electronics. A neutral sensor may be located remotely and connected to the trip unit. The connection is limited to 10m (33ft). Due to the air core sensor’s ability to handle a wide range of primary currents without distortion, Ground Fault sensing is accurate for a wide range of phase and current inputs.

The EntelliGuard TU trip unit is able to accept input from an externally calculated Ground Fault current. The Ground Fault current may be derived using a single Zero Sequence CT or multiple phase CTs connected in a residual summation scheme. External CE marked Zero Sequence or ground return CTs are available for IEC applications, but are not UL Listed. Phase CTs used for a summation connection are UL Listed. Applications for this capability include sensing at the ground return connection for a transformer or generator as well as application in multiple source grounded systems.

All UL 489 and UL 1066 circuit breakers are limited to a maximum nominal pickup setting of 1200A per the National Electrical Code or 60% of the sensor size, whichever is lower. The minimum setting is 20% of sensor size. The available maximum settings per sensor may be seen in Table 3.8.

selective setting possible while still meeting the applicable UL and NEC standards. In many cases, an 800A circuit breaker may be used under a 1200A ground fault curve selectively (Fig. 3.9).

Ground Fault Time Delay Bands used in the EntelliGuard G circuit breakers range from 42msec to 942msec. In Power Break I, Power Break II, WavePro and AKR circuit breakers, the minimum GF Time Delay Band is 58msec and the maximum is 417msec.

The available minimum settings per circuit breaker type are shown in Table 3.9. The maximum Time Delay Band setting for all circuit breakers is 0.940sec with a 1sec clear.

The EntelliGuard TU trip unit may provide several types of Instantaneous protection, depending on the circuit breaker in which it is installed. The different types of Instantaneous protection are as follows:

• Adjustable Selective Instantaneous: Provided on Power

TU Trip Unit System

Each of these Instantaneous trips provides optimum protection, selectivity or both as required for different applications, subject to the capabilities of the respective circuit breakers in which the trip units are installed.

The EntelliGuard TU uses an exclusive algorithm, developed by GE, to recognize the wave shape of fault current within a cycle. With the improved analysis of the fault current wave shape, the trip unit allows the circuit breaker to trip immediately yet provide superior selectivity when used above current limiting circuit breakers or fuses. In many cases, the trip unit’s Instantaneous pickup may be set quite low yet allow for complete selectivity up to the circuit breaker’s full withstand level. For a list of possible selective combinations of GE circuit breakers employing the EntelliGuard TU trip unit and various downstream overcurrent devices, see GE publication DET-537.

The EntelliGuard TU trip unit can be furnished with one of two Instantaneous adjustment ranges. The standard adjustable range may be as high as 15X the trip plug value on all UL 489 or UL 1066 circuit breakers. An optional Extended Range Adjustable Selective Instantaneous, as high as 30X, may be provided for UL 1066 Listed Low Voltage Power Circuit Breakers (LVPCBs). LVPCBs also allow for this adjustable Instantaneous trip to be turned off. The minimum adjustable Instantaneous pickup setting for all circuit breakers is 2X the trip plug rating. The available maximum pickup settings are described in Table 3.10. The maximum Instantaneous pickup is limited by the circuit breaker’s withstand rating.

The Adjustable Selective Instantaneous will clear a fault in three cycles when used in 60Hz or 50Hz applications. Zone Selective Interlocking (I-ZSI) may be used with this Instantaneous function, allowing several breakers with overlapping Instantaneous protection to be selective with each other. Because each circuit breaker is set to trip Instantaneously for faults within their respective zones of protection, fast protection and selectivity are achieved simultaneously.

The special selective Instantaneous algorithm allows any circuit breaker above current limiting devices to be set with a relatively low Instantaneous pickup and still achieve significant selectivity. The system may be able to provide Instantaneous protection for most faults, including high impedance arcing fault, while maintaining significant levels of selectivity. Figures 3.11 and 3.12 later in this document

demonstrate the performance of the Instantaneous ZSI capability

Reduced Energy Let-Through (RELT) Instantaneous Trip

24-May-12 Section 3. EntelliGuard TU Trip Unit System

The EntelliGuard TU trip unit’s HSIOC pickup is similar to the fixed override used by other trip units and circuit breakers in the industry. In EntelliGuard G, the HSIOC setting is changed automatically by the trip unit if the normal adjustable Instantaneous is turned off (LVPCB only). When adjustable Instantaneous setting is turned off, HSIOC nominal setting becomes 98% of the circuit breaker’s Short Time withstand setting. In all other cases, in the EntelliGuard G family of circuit breakers, the HSIOC is set high enough to allow full selectivity up to the circuit breaker’s short time withstand rating.

For circuit breakers with an HSIOC trip function, the location of the HSIOC trip is shown by the line that reaches the

0.01sec axis at the bottom of the TCC. The location of that line is shown in Table 3.11. In many applications, the

EntelliGuard G circuit breaker with an EntelliGuard TU trip unit will be completely selective up to the HSIOC pickup or

This form of Instantaneous protection is provided on all EntelliGuard G circuit breakers. This function provides protection in case the circuit breaker is closed on an unusually high current. A circuit breaker that experiences 15 times (15x) or more its plug rating is possibly closing in on a fault caused by incorrectly wired conductors, forgotten grounding cables or some other type of unusual low impedance fault.

Alternatively, it is closing on a very low impedance arcing fault. In either case, there is a possibility that equipment may be damaged by the high fault current or an arc flash hazard has been inadvertently created. The MCR provides very fast protection when the circuit breaker is closed and for the first six cycles thereafter. After the six cycles have elapsed, the MCR is turned off and the circuit breaker reverts to its adjustable Instantaneous pickup and HSIOC if provided. The

MCR will clear fault current in 40msec or less. the circuit breaker’s full short circuit rating, even with the adjustable Instantaneous on.

• All UL Overrides are -0% tolerance, ANSI Override pickup at -0% or -9% based on Adjustable Selective Instantaneous being on or off.

The EntelliGuard TU trip unit provides an optional second, user-adjustable, RELT Instantaneous trip, which allows a circuit breaker to be temporarily set to a more sensitive pickup to provide better protection, only when better protection is needed and some selectivity may be sacrificed. The RELT pickup is adjustable from 1.5X to 15X of plug rating, independently of the normal adjustable selective Instantaneous. It may be set higher or lower than the selective Instantaneous.

The user must make two entries at the trip unit: (1) Pickup settings (1.5-15X of the plug) and (2) ON, OFF or REMOTE. ON/OFF enables or disables the pickup setting. REMOTE allows the RELT Instantaneous pickup to be enabled via application of 24Vdc or Vac at the RELT input terminals or serial communications via the Modbus or Profibus communication port. The RELT pickup may be enabled via serial communication or remote 24V signal, but both need to be indicating “OFF” for the RELT Instantaneous pickup to be disabled. The RELT input command may be wired to a manual switch, automatic sensor or, via external logic,

When the EntelliGuard TU trip unit has the RELT

Instantaneous pickup enabled, the trip unit provides a

feedback signal via an optically isolated dry contact and

serial communication. This provides positive feedback that

the trip unit has received and reacted to the RELT Enable

command.

The EntelliGuard TU trip unit’s RELT capability provides the

ultimate in user flexibility for wiring and controlling an

alternate Instantaneous setting for temporary use to reduce

personnel hazard. The RELT Instantaneous pickup clears

fault current in 42msec or less at 60Hz.

RELT capability may be provided on a trip unit with or

without control power. If 24V is provided to the RELT input,

the trip unit will use the RELT Instantaneous trip setting.

However, without control power connected to the trip unit

permanently, indication that the trip unit is in the RELT mode

may not be reliably communicated. If reliable

communication that the trip unit is in the RELT mode is

desired, it is suggested that the trip unit be permanently

connected to 24Vdc control power.

TU Trip Unit System

The RELT switch may be connected to a manually operated two-position switch, a remote sensor, or both simultaneously. The EntelliGuard TU trip unit provides a feedback capability directly from the trip so the user is able to verify that the signal was received by the trip unit and the settings have changed. Optionally, an indicating light may also be connected to the source of control power so the user knows if control power is available to change the setting. The trip unit does not require its own control power to accept a RELT input and change the Instantaneous trip pickup according to the user settings. However, if control power is available to the trip unit, the feedback signal will function immediately, rather than when the trip unit becomes self-powered through its load current (Fig. 3.10).

• This configuration provides positive indication that the trip unit has

received and processed the RELT "On" signal. It Also provides a control power check. Caution: It is recommended that RELT output be wired to an appropriate annunciation when remote activation control of RELT is used.

NOTE: When using the RELT function in conjunction with remote enable/disable control, it is strongly recommended that the trip unit be provided with permanently connected control power and that the RELT status output be assigned to a trip output contact. The trip output contact should be wired to appropriately located annunciation. The trip unit will accept a command to enable the RELT instantaneous pickup setting via local HMI control, a 24Vac/dc voltage applied at the input terminals or serial communication. Regardless how the enable command is received, the trip unit will be in the RELT mode when protection is required. However, the status indicating contacts will only close if the trip unit is powered through the internal current transformers or 24Vdc control power. Lack of 24Vdc control power could provide unreliable indication of RELT status due to low load conditions on the circuit breaker.

The EntelliGuard TU trip unit’s ZSI capability differs from that found in other circuit breaker trips in two significant ways:

1. It allows independent and separate settings of the unrestrained (in zone protection) and the restrained (back up protection) bands.

2. It provides simultaneous and independent ZSI of both the Short Time and Instantaneous protection. This allows each circuit breaker to zone interlock with upper tier circuit breakers between ST band to ST band, Instantaneous to Instantaneous, or Instantaneous to Short Time.

The EntelliGuard TU trip unit's fast ZSI system is able to interlock Ground Fault, Short Time and Instantaneous. When required for feeder selectivity the main is able to be set faster than the feeder without any sacrifice in selectivity. As long as the main breaker's pickup is set above the feeder's pickup the two devices will remain selective. Each circuit breaker in a ZSI scheme allows separate user settings for the restrained (backup) and unrestrained (in zone protections) for ground fault and short time protection. For the lowest tier device in the scheme the restrained and unrestrained are set to the same values. For instantaneous protection there is only one pickup setting required.

Instantaneous protection may also be interlocked such that all circuit breakers above the one whose zone has the fault will shift from Instantaneous clearing to a 0.058msec time band. Since it is expected that faults of enough magnitude to engage the Instantaneous pickup are dangerously high, all zone selective interlocked Instantaneous trips that receive a restraint signal are shifted to the same band. Should the bottom circuit breaker fail to clear for whatever reason, quick back up protection from both ties and feeders is provided.

Short Time and Ground Fault bands for zone interlocked circuit breakers may be set to any band available to the trip. Figure 3.11 shows two circuit breakers set to protect at their unrestrained settings. Figure 3.12 shows the same two circuit breakers while a fault is detected below the lower circuit breaker in the system and after a restraint signal is received by the upper circuit breaker’s trip unit. The upper circuit breaker’s Short Time band has shifted from the user setting of 0.025sec to a user set restrained band of 0.092sec. The Instantaneous has shifted from the adjustable selective Instantaneous band clearing in 0.050sec to the fixed restrained band of 0.058sec, clearing in 0.113sec. This allows the lower circuit breaker to clear faults within their zone of protection above 7,000A RMS and 11,000A RMS respectively, clearing under 100msec, while maintaining full selectivity for faults up to 85,000A.

TU Trip Unit System

The EntelliGuard TU trip system is composed of trip units and trip rating plugs along with the sensors and wiring provided in the EntelliGuard G circuit breaker to support the trip. Rating plugs are used to lower the Long Time adjustment range of the sensor provided in the circuit breaker.

The EntelliGuard TU trip rating plugs are unique in that they can be used with multiple trip units and circuit breakers within a specific sensor range, rather than only with a single specific sensor. The trip rating plug catalog number, shown in Figure 3.13, identifies the rating as well as the minimum and maximum sensor rating the plug may be used with. Table 3.12 lists trip rating plugs available for each sensor. Table 3.13 lists the two-digit codes used within the trip rating plug catalog numbers and the sensor current ratings to which they are mapped.

TU Trip Unit System

EntelliGuard G circuit breakers will accept a Universal Spare Trip Unit. This unique trip unit may be used in any EntelliGuard G circuit breaker regardless of frame size, sensor size, short circuit rating or whether the circuit breaker is listed under UL 489, ANSI/UL 1066 or IEC 947 standards. Should any circuit breaker’s trip unit fail to operate for any reason, this one universal trip unit may be used as a replacement.

Once an EntelliGuard TU trip unit, including the Universal Spare Trip Unit, is associated with a specific EntelliGuard G circuit breaker, it may only be used with that specific circuit breaker. If swapping between EntelliGuard G circuit breakers is required, a trip unit may only be swapped between circuit breakers with equal sensor ratings, short circuit ratings and standard listing. Before the circuit breaker may be used with a swapped or new trip unit, the trip unit must be mapped to the circuit breaker.

The Re-mapping procedure is done by Pressing simultaneously the "Right", "Left", and "Up" Arrow all at the same time (should be able to do with one hand). "BIM OK" will be flashing in the upper left hand corner of the LCD when this is performed. Another Method is to use Modbus Command 107 "Upload BIM" Either procedure requires the trip unit to be mounted to the breaker and control power be provided to the trip unit from permanently connected control power or a portable power supply via the front port.

Front 24VDC Power is provided by Either the GTUTK20 Test Kit or the Portable Battery Pack, TVPBP and TVPBPACC.

All Universal Trip units have the following format G1X00----RXXXX. The middle 5 digits describe the trip unit protection options and features.

The EntelliGuard TU offers various protective and alarm relay functions that may be displayed on the LCD screen, assigned contact outputs or communicated serially (Table

3.19).

Protection relays may be set by the user to alarm, trip the circuit breaker or both. Alarms and trips are displayed on the local LCD trip and communicated serially. Alarms may also be assigned to one of two output contacts. The Trip Alarm settings are independently set for each relay function.

This function compares the highest or lowest phase voltage with the average of all three phases and initiates a trip if the difference exceeds the set point. The true RMS voltage is computed for each phase (Table 3.20).

This function measures the true RMS voltage in all phases and initiates a trip if any phase voltage drops below the set point.

The Trip Unit gets its voltage input from an externally mounted central module, called a Voltage Conditioner. The Voltage Conditioner is wired to each trip unit in a line-up. Voltage Conditioner Cat#: PLVC1G01

This function determines if the relay trips when all threephase voltages drop to zero volts. Uses the same timing set for the Under-Voltage Relay (Table. 3.22).

averaging. The trip unit calculates a rolling average of breaker power over this time interval.

The Trip unit provides two types of current alarm: Current Alarm 1 and Current Alarm 2. The current alarm’s ON/OFF pickup settings are user adjustable from 0.5 to 1.0 xIn in steps of 0.05. The trip unit does not allow the current alarm OFF set-point to be set above the ON threshold. If the highest measured phase current goes above the current alarm 1 or current alarm 2 ON set-point, and then remains above the set-point for more than 60sec, the output will close if assigned to either of these alarms. If the current falls below the current alarm 1 or current alarm 2 set-point for more than 60sec, the output, if assigned to the current alarm, will open. This is a definite time function with a 60s delay and a 60sec cool down period. Both periods are fixed.

The trip unit is able to receive two hardwired input signals. Either can be a 24Vac or Vdc signal. The inputs can be assigned to three main functions:

• Reduced Let Through Energy "RELT" instantaneous

protection "ON".

• Breaker "Trip"

• Breaker "RESET"

Note: When RELT is Optioned, Input1 is dedicated to RELT. Contacts are rated for 30 VDC/25 VAC MAX, 1 Amp.

The number of outputs available varies by breaker. The EntelliGuard G circuit breaker has three. These outputs are relay contact outputs to secondary disconnect. Each output can be configured per Table 3.26.

When a fault has taken place, it is important to visualize the event. The Waveform Capture option included in the advanced trip unit can track and visualize any fault event. The device tracks eight cycles, four before and four after the event, with resolution of 48 samples per cycle at 60Hz and stores the results in memory. It registers events in all three phases and the neutral. After the event, the waveform is stored in COMTrade format and can be accessed by using the waveform client module of the Enervista software. When the upload into this software is complete, the tripuUnit will reset this function and be available to register the next event.

24-May-12 Section 4. Accessories

A wide range of optional accessories are interchangeable across all EntelliGuard G power circuit breakers, regardless of nominal rating or envelope/frame size. As shown in Figure

4.1, each accessory incorporates easy-fit design features for quick installation, either at the factory or in the field. NOTE: Replacement accessories have an “R” at the end of the catalog number as shown in the tables. All Coils are Conformal Coated for increased reliability in humid/damp environments

The unique motor/gearbox unit is specially designed to operate with the full range of EntelliGuard G breakers. It is easily installed with three heavy-duty bolts. After a breaker close operation, the unit automatically recharges the spring and makes it ready for immediate re-close should the need arise. High speed recharging ensures that the springs are fully charged within approximately three seconds following a release. All electrically operated (EO) ANSI/UL breakers are equipped with “Spring Charged” contacts for status indication (Table 4.1).

Two, easy-to-fit, clip-on closing coil options with simple, plug-in connections are available. Both options offer electrical remote release of the spring charged closing mechanism. Both options include a standard anti-pump safety feature ensuring that the close signal must be released before further close commands are allowed. The Command Close Coil additionally provides for local breaker close and remote breaker close over communications via the EntelliGuard Trip Unit (Table 4.2).

This module energizes the closing coil to cause the breaker to close whenever control power is applied to the accessory and when commanded from the breaker trip unit or breaker front panel push button (electrical closing.)

Energizing the shunt trip (ST), via local or remote input, will instantaneously activate the circuit breaker mechanism, ensuring a rapid open operation. The shunt trip is continuously rated and does not require an auxiliary switch in series with the coil. The shunt trip is a straightforward, field installable accessory available in wide range of voltages. See Table 4.3.

A plug-in module is available to provide status indication via the secondary disconnects and trip unit. Coil Signaling Contacts are available for closing coils, shunt trips and under voltage releases (Table 4.4). Contact is mounted on top of the Accessory Device. One of the low signal (Hi-Fi) contacts is always wired to the tip Unit.

The UVR instantaneously activates the circuit breaker trip mechanism when the source voltage drops below the low voltage threshold. The UVR is also a simple, field installable device. NOTE: This accessory acts as a permissive; it is a novoltage/no-close device. The circuit breaker cannot be closed (manually or electrically) unless the undervoltage release coil is energized above the required threshold. The undervoltage release with fixed time delay is specifically intended for applications where a delay period (ride-through) is required due to potential voltage events. The delays are 50msec when system voltage drops to 50% and 20msec when system voltage drops below 50% (Table 4.5).

The de-energized operation of the Undervoltage release can be delayed. This optional, externally mounted module has an adjustable time delay of 0 sec to 3 sec. The device can be implemented to prevent undesired breaker tripping due to momentary voltage interruptions and is connected in series with the Undervoltage release. The time delay is in addition to the time delay from the breaker mounted UVR accessory. The time delay module starts counting at 50% of rated voltage (Fig. 4.2 and Table 4.6).

These contacts, as shown in Table 4.8, indicate that the following conditions are met and the circuit breaker can be closed:

• The circuit breaker is open.

• The closing springs are charged.

• The circuit breaker in not locked/interlocked in open

position.

• There is no standing closing signal.

• There is no standing opening signal.

Each breaker accepts a maximum of four coils in the combinations shown in Table 4.7. The four positions can be filled by the following four devices: one Close Coil, one Shunt, one UVR, and the final fourth position can either be a Shunt Trip or a UVR. All coils are mounted from the front and snap onto the mechanism after the fascia is removed.

All Coils are

Conformal Coated for increased reliability in humid/damp environments.

Available as an option for mounting within the base of the cassette/substructure, the carriage position switch provides six single-pole changeover contacts (single pole, double throw) for local or remote electrical indication of the circuit breaker status: CONNECTED, TEST and DISCONNECTED. The DISCONNECTED position is indicated only when minimum isolating distances between contacts on both the main and auxiliary circuits have been achieved. This option is in addition to the mechanical indicators, which are fitted as standard. When installed, the carriage switch is IP2X protected. For use with drawout breakers/cassettes Tables

The drawout mechanism allows the breaker to be racked in four distinct positions (CONNECTED, TEST, DISCONNECTED, WITHDRAWN).

Available for fixed and draw-out circuit breakers, these units enable the direct interlocking of EntelliGuard G circuit breakers, either mounted side-by-side or stacked. The interlocking mechanisms are connected by a specially designed cable or rod in a 1 from 2, 1 from 3, and 2 from 3 configuration, and any mix of current ratings/pole configurations can be accommodated Table 4.18).

The Bell Alarm provides remote indication that the circuit breaker has opened because of an electrical fault. The Lockout feature is integral to the trip unit. When a Bell Alarm is supplied with the breaker, the Trip Unit dial is set and locked to the manual position. In order to re-close the breaker, the Lockout button must be pushed in/reset on the Trip Unit 1-Form C contact (Tables 4.21 and 4.22).

Inputs and outputs to the circuit breaker are wired through secondary disconnects located on either the top or the side (Envelope 1 only) of the breaker. The plug-style secondary disconnects engage mating disconnects in the breaker cubicle when the breaker is in the TEST or CONNECT position. Up to 78 points are available so that all breaker accessories can be wired to dedicated disconnect points (Tables 4.24 through 4.29). Block B is ordered separate for cassettes, Cat. No. GSDWTR.

The EntelliGuard TU Trip Unit provides a non-core CT input for zero sequence or residual summation current. The expected ratio is 1A = 100%.

The Neutral Rogoswki CT’s are used to measure the Neutral Current and is required when Internal Ground Fault is selected on the trip unit. There are two types available:

1. Encased with Terminal Screws: The Rogowski coil is

encased with two terminal screws. No additional mounting hardware is required as the encasing is molded to the mounting dimensions. Table 4.30

2. Loose Rogowski Coil with separate mounting

hardware: The coil and mounting hardware are separate. The coil comes with the two wire leads for connection to a terminal block. Table 4.30a

An optional complete IP54 front door panel is available when a higher degree of protection is needed (Table 4.31).

Used with either manual or motor charged circuit breakers, the counter provides an accurate record of the cumulative number of complete breaker closing operations (Table 4.31).

Rejection Device

24-May-12 Section 4. Accessories

The remote racking operator allows the user to move a draw out circuit breaker between the CONNECT and DISCONNECT positions via an electric racking gear head motor and the Cassette housing the breaker. The remote racking operator requires 115VAC, 60Hz control power. A control box connected to the operator with a thirty-foot chord permits control from a remote location.

All EntelliGuard G circuit breakers can be fitted with a grounding/earthing device, which has a short circuit rating equal to the breaker withstand rating. This permits either the feeder cables or the busbar to be safely grounded and locked during system maintenance operations (Table 4.36).

2

A factory-installed rejection feature prevents mismatching breakers and cassettes/substructures. This prevents (a) inserting a breaker with a lower rating into a higher rated cassette/substructure and (b) inserting a higher rated breaker into a lower rated cassette/substructure. Misinsertion Interlock catalog number is GREPM.

This option provides factory installed interlocking devices for

installation between separate circuit breakers (baseplates and mechanism). This safeguard ensures that a circuit breaker cannot be closed unless the dedicated key has been inserted and secured within the lock.

If selecting a Draw Out Breaker (Digit 6), consider putting the Key

Interlock on the Cassette versus the breaker. This enables the ability to swap breakers without having to change the key interlocks.

Some installations use multiple power sources that are required to supply

energy simultaneously, alternately, or, in a specified sequence. EntelliGuard G Circuit Breakers can be used to interconnect these sources and be electrically and mechanically interlocked to provide the necessary transition and protection. Mechanical Interlocks are available for fixed and draw out circuit breakers. The interlocks enable directly interlocking breakers that are mounted side by side or in vertical stacks. The interlocks consist of two components: (A) The factory-installed bracket fitted to the breaker (fixed breakers) or the cassette (drawout breakers), and (B) The field-installable interconnecting cables available in lengths of 1.0, 1.6, 2.0,

2.5, 3.0, 3.5 and 4.0m (ordered separately). Refer to Section 4 for interlocking schemes.

under the applicable UL, IEC and ANSI standards as shown in the various ratings tables. Switchgear equipment is typically sized to match the frame ratings and physical size. Switchboards may be sized to match the installed circuit breaker’s sensor rating.

Equipment cubicles or device mounting provisions are normally mechanically interlocked such that equivalent frames may be installed within a specific cubicle or space. When exchanging circuit breakers for maintenance purposes, care should be exercised so that there is no attempt to install a circuit breaker with a rating higher than what the equipment was designed to accommodate, even if the physical size seems similar.

The EntelliGuard G family of UL devices is available with short circuit ratings as high as 150kA at 480V, and withstand ratings as high as 100kA. UL1066 and ANSI C32 ratings are based on various tests performed at rated voltage plus 6%. Hence it is common to see low voltage circuit breakers listed as suitable for 254, 508 and 635V. Any UL 1066 listed device must be tested at these higher voltages if listed at the normal nominal voltage of 240, 480 and 600V. UL489 circuit breakers are tested at the nominal voltage. Both circuit breakers are subject to dielectric testing after interrupting faults to ensure the ability to sustain voltage.

Short circuit interrupting ratings are a measurement of the circuit breaker’s ability to interrupt a particular value of fault current at a maximum power factor (also expressed as X/R ratio). For fault currents above 20,000A RMS, UL489 circuit breakers are tested at 20% power factor and UL1066 circuit breakers are tested at 15% power factor. When fault currents have power factors lower (higher X/R) than the test power factor, the circuit breaker’s short circuit rating must be adjusted to compensate for the fault’s lower PF. The adjustment is performed as shown in Figure 6.1. Table 6.2 shows various asymmetrical peak ratios for various power factors and X/R ratios. A power factor of 100% yields a symmetrical fault and hence the peak over RMS ratio is 1.41.

CB’s Test Peak = Derate Ratio Fault Peak

Consider a system where the fault current has an X/R ratio of 10 and the calculated RMS value is 92,000. A circuit breaker with a stated interrupting capability of 100,000 is being considered. Since the fault’s X/R ratio is higher than the UL489 rating at 4.9, the circuit breaker’s rating, 100kA, must be multiplied by 2.18/2.46 (from Table 6.1). The ratio is .89. Hence, the circuit breaker must be considered as if it is only rated for 89,000A. The UL489 100kA rated circuit breaker is not suitable for the application because its derated 89kA rating is below the available fault current of 92kA.

Consider an equivalent UL1066 circuit breaker tested at an X/R ratio of 6.6. The UL1066 circuit breaker must be derated by 2.31/2.46, which yields 0.94. The UL1066 circuit breaker is then de-rated to 0.94 times 100kA. The UL1066 circuit breaker is rated higher than the available fault current of 92kA and hence could be considered for the application.

Instantaneous adjustment capability for any circuit breaker is intrinsically connected to the circuit breaker’s withstand rating and the trip system’s sensing methods. In the case of the EntelliGuard G family of circuit breakers, high withstand ratings allow for a broad range of instantaneous trip options. The trip system relies on high accuracy air core sensors not encumbered by the saturation concerns associated with iron core sensors used in many other trip systems. This allows the

EntelliGuard trip system to take full advantage of the circuit breaker’s withstand rating, providing adjustable settings and full selectivity right up to the circuit breaker’s high withstand level. EntelliGuard G circuit breakers, in conjunction with EntelliGuard TU trip units with GE’s unique “selective instantaneous” algorithm, allow selectivity capability as high as 100kA with instantaneous on, and set at surprisingly low values. The EntelliGuard family of devices provides multiple solutions for your selectivity and protection problems.

Low Voltage Power Circuit Breakers (LVPCBs) listed to UL1066 have defined fault current withstand currents. EntelliGuard G UL489 Insulated Case Circuit Breakers also have substantial withstand ratings. The stated withstand current (Icw) allows the instantaneous protection of LVPCBs to be turned off or set at very high values, and it’s what allows the short time bands of both types of circuit breakers to be delayed as much as 0.5sec. EntelliGuard G UL1066 LVPCBs with EntelliGuard TU trip units are available with two different instantaneous adjustment ranges to take full advantage of this capability.

The standard instantaneous adjustment range is 2-15X, adjustable in 1/2X increments on all UL 489 and UL1066 circuit breakers. EntelliGuard TU trips offer, for UL1066 LVPCBs only, an extended Instantaneous adjustment range that allows the instantaneous pickup to be continuously adjusted up to 30X, adjustable in 1X increments above 15X the rating plug. The maximum adjustable pickup setting is limited to approximately 95% of the circuit breaker’s withstand rating, or 30X trip plug current rating, whichever is lower.

The EntelliGuard G’s wide range of instantaneous adjustability allows for maximum flexibility in providing the settings that are required for selectivity or for optimum protection. Its capability is limited by its withstand rating and the instantaneous override. An instantaneous override is used in some circuit breakers to ensure that, if a fault exceeds the circuit breakers withstand capability, the circuit breaker trips quickly. In all UL489 EntelliGuard circuit breakers, the override protection is designed such that selectivity up to 100% of the stated circuit breaker’s withstand rating is possible.

In UL1066 LVPCBs, maximum selective capability is achieved by using the adjustable instantaneous algorithm, even if it is set at maximum. When the adjustable instantaneous is enabled, regardless of setting, the override protection is set so that it will not trip for faults below the circuit breaker’s withstand rating. If the adjustable instantaneous is disabled (turned off), then the override automatically adjusts downward by approximately 9%. This lowers the maximum

selective capability to 91% of the circuit breaker’s withstand rating. The EntelliGuard G LVPCB may be selective up to the full withstand current with adjustable instantaneous on and 91% of withstand rating with adjustable instantaneous off.

The EntelliGuard TU trip unit also offers a second adjustable instantaneous trip called the Reduced Energy Let-Through (RELT) instantaneous pickup. This trip offers a faster algorithm suitable for application as alternate instantaneous pickup setting for temporary use when faster and more sensitive instantaneous protection is desired. The RELT setting is determined by the user and may be adjusted from

1.5X to 15X rating plug. Once set, the RELT function may be enabled or disabled locally at the trip unit or remotely via a 24Vac/dc signal, or serial communications.

When the trip unit receives a RELT enable command, it issues a feedback signal indicating the RELT setting is now active. The user may connect the RELT enable input to any 24Vac/dc source, such as a manual switch, automatic sensor, or both. The feedback signal may be connected to any desired signaling means with the proper ratings. For further details see Section 3 of this application guide.

EntelliGuard G circuit breakers have defined close and latch ratings as shown in Tables 6.2 through 6.4. The close and latch rating is a measurement of the circuit breaker’s ability to close and latch closed on a fault. This value must be high enough to allow a circuit breaker to handle large transient inrush currents associated with certain types of loads, such as energy efficient motors or large capacitor banks.

EntelliGuard G circuit breakers are provided with values that are high relative to the circuit breaker’s load carrying capacity. The trip system provides a type of instantaneous protection called a Making Current Release (MCR) to provide more sensitive protection when closing. Should the trip system measure higher current than the MCR setting, it is very likely that the circuit breaker has been closed on a bolted fault, or low impedance, arcing fault. If that is the case, the MCR instantaneous will provide very fast protection, minimizing damage and hazard.

EntelliGuard G circuit breakers are designed to provide long life, even in operationally difficult environments. However, different standards have different ways of measuring and qualifying circuit breaker operations, hence slightly different numbers may apply to similar circuit breakers when defined within the context of different standards. Tables 6.5 and 6.6 describe the endurance parameters for the circuit breaker family.

Per industry standards, operations are listed based on no maintenance during the testing. However, if some maintenance is done of some of the current carrying parts and arc chute, then over 20,000 electrical and mechanical operations are possible.

There are six application factors to consider in selecting current rating for a circuit breaker. These are:

1. Size of the cable or bus used in the line and load

connections.

2. Actual installed ambient temperature.

3. System operating frequency.

4. Altitude of the installation.

5. Type of loading of the protected circuit.

6. Design safety factor.

The following simple relationship combines these six application factors into a single equation:

CR Required circuit breaker current rating, amps IA Actual load current, amps A Cable or bus sizing factor B Ambient temperature rating factor C Frequency rating factor D Altitude rating factor E Load class rating factor F Safety factor

The thermal design of a circuit breaker takes into account the ability of the line and load cables or buses to act as heat sinks. For UL489 Listed circuit breakers, UL has assigned specific cable or bus sizes for each current rating. Generally, these assignments are coordinated with specific conductor temperature ratings. When using a conductor with an increased temperature rating, the higher rating decreases both the cross-sectional area and its ability to conduct heat from the circuit breaker. If an

24-May-12 Section 6. Application Data

EntelliGuard G circuit breaker is used with cables directly connected, contact your GE application engineer for information to ensure proper cabling information. Cable with insulation ratings above 75°C may be used, providing it is sized to 75°C ampacity per the NEC or other applicable codes.

Ambient temperatures have a wide effect on the rating of the breaker-cable system. While the internal sensing and tripping circuitry in EntelliGuard TU trip units are ambient insensitive, high-ambient temperatures may cause internal components to exceed operating temperature limits. Low temperatures substantially increase the current-carrying capabilities of the breaker-cable system until other limiting factors occur (e.g., lubrication problems or mechanical binding of internal parts due to differential contraction). The ambient temperature around an EntelliGuard G breaker should not be less than -20°C nor exceed 70°C.

Ambient temperature always refers to the temperature of the air immediately surrounding the breaker and not the temperature of the air outside the breaker’s enclosure. Room or outside air temperatures only establish the thermal floor to which all other heating is added. To convert breaker ambient from room ambient, it is necessary to know the temperature rise within the equipment housing the breaker. Temperature rise is a function of several variables, including heating caused by other equipment, ventilation, solar heating, factors relating to group mounting and the free surface area of the breaker’s enclosure. Once the device’s ambient temperature is determined, select Factor B from Table 6.7.

40 90 1

1 Average air temperature over a 24-hour period outside the breaker’s insulated case, but inside the enclosure. 2 Cable (wire) must be based on 75°C current rating per Table 3 10-16, current National Electrical Code.

All UL EntelliGuard circuit breakers may be applied at their published ratings on 50Hz and 60Hz power systems. At nominal system frequencies less than 50Hz but above direct current, digital solid-state trip may become inaccurate. On direct current systems, digital solid-state

trip units are completely inoperative. EntelliGuard G circuit breakers may be used on DC applications, but EntelliGuard TU trip units may not.

System operating frequencies above 60Hz may change the performance and ratings of circuit breakers by heating metallic parts and significantly reducing interrupting capacity. EntelliGuard TU trip units are not suitable for applications at 400Hz.

For operating frequencies of both 50Hz and 60Hz, the operating frequency rating Factor C = 1.00. For operating frequencies other than 50Hz and 60Hz, contact your GE applications engineer.

EntelliGuard G UL circuit breakers are designed for operation at altitudes from sea level to 6000ft (1800m). Reduced air densities at altitudes above 6000ft affect the ability of the circuit breaker to both transfer heat and interrupt short circuits. Determine the altitude of the breaker’s installation, and select the altitude rating - factor D from Table 6.8.

The type of load and its duty cycle must be considered in the application of EntelliGuard G circuit breakers. Loads such as capacitors and electromagnets require a substantial and continuous de-rating factor if the breaker is normally used to switch the load. With loads such as resistance welders, the breaker’s continuous current rating must be no less than 125% of the welder’s 100% dutycycle rating.

In general, circuit breakers are intended for the protection of insulated cable. Where a circuit breaker is intended to protect load equipment, prudent engineering practices call for obtaining factory review and concurrence with the selection of a specific protective device. Load class selection Factor E for typical applications are listed in Table 6.9.

*Use this factor to either plugging duty or starting more than 25 times per hour, where the rms current cannot be easily calculated.

A safety factor is used to provide a design margin between the rating of a circuit breaker and the derived operating current using all of the applicable selection factors. A safety factor of at least 10% is often used to ensure the circuit breaker is adequately sized. In addition it may be useful to consider future growth.

All EntelliGuard G circuit breakers are 100% rated except for the 6000A stationary mounted UL 489 circuit breaker. Circuit breakers that are 100% rated are not required to be sized at 125% of the expected load. However, it is recommended that a safety factor, as described above, always be considered when selecting overcurrent device sizes.

An important consideration may be the circuit breaker’s desired selective and protection performance within the context of the system where it is installed. Certain settings are functions of the trip plugs, others of the sensors. In Table 3.14 you will find the sensors available on a per frame basis. Table 3.12 identifies the trip rating plugs available for each sensor. Table 6.10 identifies the relationship between specific circuit breakers and trip parameters.
