De-Energizing the Device

Isolation Capacity

TeSys GV5 / GV6 devices offer positive contact indication and are suitable for isolation in accordance with IEC/EN 60947-1 and 2 standards. The O (OFF) position of the actuator is sufficient to isolate the device concerned.

The following marking on the rating plate label indicates that the device is capable of isolation:

To confirm this capability, IEC/EN 60947-1 and 2 standards require specific shock withstand tests.

TeSys GV5 / GV6 devices can be locked in the O (OFF) position to allow work to be carried out with the power off in accordance with installation rules. The device can only be locked in the open position if the device is in the O (OFF) position.

NOTE: Locking a TeSys GV5 / GV6 device in the open position is sufficient to isolate the device.

Protection for Motor-Feeders

Introduction

TeSys GV5 / GV6 devices:

 Provide protection for direct-on-line motor-feeders and star-delta motor starters (direct-on-line starting

is the most widely used type of motor-feeder).

 Integrate the basic protections (overload, short-circuit, and phase unbalance) for the motor-feeder.  Allow protection and coordination of the motor-feeder components that comply with the requirements of

IEC/EN 60947-2 and IEC/EN 60947-4-1 standards.

 Are used to create motor-feeders with two devices.

A TeSys GV5 / GV6 device B Instantaneous protection C Overload protection D Contactor E SDTAM thermal fault module

Characteristics Defined by IEC/EN 60947-4-1 Standard

A motor-feeder must satisfy the general rules of IEC/EN 60947-4-1 standard, in particular the rules concerning the protection of contactors and motor-feeders.

In the matter of protection, this standard defines:

 Coordination of motor-feeder protections  Trip class setting value  Insulation coordination

DOCA0161EN-01 03/2020

Coordination According to IEC/EN 60947-4-1 Standard

Two types of coordination are allowed: type 1 coordination or type 2 coordination.

 In type 1 coordination, deterioration of the contactor and relay is accepted under the two following

conditions:

 The contactor or starter does not represent a danger to people or installations.  The starter can operate correctly when parts have been repaired or replaced.

 In type 2 coordination, some slight welding of the contactor or starter contacts is allowed if, following

type 2 coordination tests:

 They are easy to separate.  The control and protection switchgear functions then work without the need for repair.

To ensure type 2 coordination, IEC/EN 60947-4-1 standard lays down three Id fault current tests intended to check that the equipment behaves correctly in overload and short-circuit conditions.

Motor Operating States

Introduction

TeSys GV5 / GV6 devices consider the application to be operating as soon as the 10% of Ir pickup is crossed in a positive direction by the motor current.

Two operating states are considered:

 Startup state  Steady state

Startup State

The application is considered to be in startup state according to the following criteria:

 Start: As soon as the 10% of Ir pickup is crossed in a positive direction by the motor current.  End: As soon as the Id pickup equals 1.5 x Ir and the td time delay equals 10 s (non-adjustable

parameters). Exceeding the 10 s time delay does not result in tripping.

NOTE: The trip unit filters the subtransient state (first current peak of approximately 20 ms on contactor closing). This current peak is not therefore taken into account when assessing whether the Id pickup has been crossed.

Steady State

The application is considered to be in steady state according to the following criteria:

 Start: As soon as startup ends.  End: As soon as the 10% of Ir pickup is crossed in a negative direction by the motor current.

Operating Diagram

The following diagrams show the two cases of transition between startup and steady state:

Operating states with current I < Id before end of td Operating states with current I > Id at end of td

The system of reflex protection breaks very high fault currents by mechanically tripping the device with a piston actuated directly by the pressure produced in the device from a short-circuit. This piston operates the opening mechanism, resulting in ultra-fast device tripping

(see page 61)

DOCA0161EN-01 03/2020

Overload or Thermal Protection (ANSI 49)

Introduction

Overload or thermal protection protects all types of motor applications against overload currents.

Operating Principle

Overload or thermal protection is I

 It incorporates the motor thermal image function.  It can be configured as the Ir pickup and as the trip class (Class).

Tripping curve:

TeSys GV5 / GV6 - Protection Functions

The long-time protection is set by two dials according to the starting characteristics of the application. The pickup setting Ir for trip unit long-time protection is expressed in amperes:

 This value corresponds to the operating current used in the motor

application.

 The maximum Ir setting corresponds to the trip unit rating In.

t IDMT (Inverse Definite Minimum Time):

Ir Pickup Setting Value

The overload or thermal protection pickup (Ir) is set by using a multi-position dial.

The default Ir pickup setting value is 0.4 x In (minimum dial value).

The overload or thermal protection tripping range is 1.05–1.20 x Ir according to IEC/EN 60947-4-1 standard.

The following table shows the preset values of the adjustment dial Ir in amperes for each current rating In:

DOCA0161EN-01 03/2020 37

TeSys GV5 / GV6 - Protection Functions

Trip Class Setting Value

The trip class (Class) is set by using an adjustment dial:

 Class 5  Class 10 (default value)  Class 20

The trip class corresponds to the value of the tripping time for a current of 7.2 x Ir according to IEC/EN 60947-4-1 standard.

The following table shows the value of the tripping time depending on the current in the load for all three classes:

Current in the load Tripping time (in seconds)

1.5 x Ir 96-120 192-240 320-400

6 x Ir 5.2-6.5 10.8-13.5 20.8-26

7.2 x Ir 4-5 8-10 16-20

The precision range is -20%, + 0%

Motor Thermal Image

The model representing heat rise and cooling in a motor load is constructed according to the algorithm for calculating the thermal demand, taking account of the iron and copper losses.

The following figure represents the limit curves for the iron and copper components calculated for class 20:

Class 5 Class 10 Class 20

Thermal Memory

A Limit temperature curve for copper B Limit temperature curve for iron C Tripping curve (low envelope)

The trip unit uses a thermal memory function to protect the motor from overheating in case of low amplitude repetitive faults.

Electronic protection without thermal memory function does not protect against repetitive faults because the duration of each overload above the pickup setting is too short to cause tripping. However, each overload causes a temperature rise in the installation. The cumulative effect of successive overloads can overheat the system. The thermal memory function remembers and integrates the thermal heating caused by each pickup setting overrun. The thermal memory function remembers the thermal heating values for 20 minutes before or after tripping.

Example: Comparison of the heat rise calculation without thermal image (diagram A) and with thermal image (diagram B):

Diagram A Diagram B

0 Load control (cyclical) 1 Motor temperature 2 Thermal level calculated without thermal image (diagram A), with thermal image (diagram B) 3 Overload or thermal protection level

With thermal image, the trip unit adds the thermal effect of successive current pulses. Tripping occurs based on the actual thermal state of the motor.

DOCA0161EN-01 03/2020

Cooling Fan

Short-Time Protection (ANSI 51)

Introduction

Short-time protection protects all types of motor applications against short-circuit currents.

Short-time protection lets through motor starting currents but protects cables and motor starter devices and allows not to oversize them (useful for wide range settings devices).

Operating Principle

Short-time protection is definite time. It can be configured as the Isd pickup.

Tripping curve:

Item Function Description

A Ir Overload or thermal protection pickup

C Isd Short-time protection pickup

D tsd Short-time protection fixed time delay

Isd Pickup Setting Value

Step Action

1 Set the long-time protection first: the setting pickup is Ir (A).

2 Turn the Isd adjustment dial to the value required. The setting range is 5 to 13 x Ir in steps of Ir.

3 Isd is set to Ir (A) x Isd setting.

The precision range is +/-15%.

The short-time protection pickup Isd is set by using a multi-position dial. The setting value is expressed in multiples of Ir.

tsd Time Delay Value

The time delay cannot be adjusted.

 The hold time is 20 ms.  The maximum breaking time is 60 ms.

DOCA0161EN-01 03/2020

Instantaneous Protection (ANSI 50)

Introduction

Instantaneous protection protects all types of motor applications against very high intensity short-circuit currents.

Operating Principle

Instantaneous protection is fixed: the pickup value is determined by the current rating In. Protection is instantaneous.

Tripping curve:

TeSys GV5 / GV6 - Protection Functions

Phase Unbalance Protection (ANSI 46)

Introduction

Unbalances of the motor phase currents lead to significant heat rise and braking torques that can cause premature deterioration of the motor. These effects are amplified during startup: protection must be almost immediate.

Description

Phase unbalance protection:

 Calculates the current unbalance for each phase, compared to the average current, expressed as a

percentage:

 Compares the value of the maximum current unbalance with the Iunbal protection pickup.

The following diagram shows a maximum positive unbalance on phase 2:

If the maximum current unbalance value is higher than the phase unbalance protection Iunbal pickup, the tunbal time delay is actuated.

Phase unbalance protection cannot be deactivated.

Phase unbalance protection is activated during startup and in steady state.

DOCA0161EN-01 03/2020

Operating Principle

TeSys GV5 / GV6 - Protection Functions

 The phase unbalance (or phase loss) protection trips if the current unbalance exceeds the 30% fixed

pickup Iunbal during a fixed tunbal time delay. The tunbal time delay differs according to the motor operating conditions:

 Start-up phase: tunbal = 0.7 s  Steady state phase: tunbal = 4 s

Phase loss is an extreme case of phase unbalance and leads to tripping under the same conditions.

During startup:

 A: Activation of startup phase.  B: Activation of protection time delay as soon as the pickup is

crossed.

 C: Protection tripped at the end of the fixed time delay of 0.7 s.

Contactor Control

Item Description

SD1, SD3 Thermal fault module input power supply

SD2 Overload fault signal output. This output maintains its state until reset.

SD4 Contactor control output

KM1 LC1D or LC1F contactor

KA1 CA2 or CAD-type control relays

Output 1 (SD2/OUT1): normally open, indicates thermal faults.

Output 2 (SD4/OUT2): normally closed, opens the contactor KM.

Outputs are activated 400 ms before the device trips in the case of:

 Overload or thermal protection  Phase-unbalance protection

Contactor control by the output 2 signal (SD4/OUT2) optimizes continuity of service and provides the following additional benefits:

 Lower risk of motor deterioration.  Activation of the output indicates that the application is not working normally. Abnormal operation is not

the result of an anomaly or internal fault in the motor-feeder.

 The cause of this abnormal operation can be temporary (for example, a voltage drop causing an overly

long starting time).

When the cause of the overload or unbalance has disappeared, the equipment can be powered up again.

NOTE: To control a contactor with a consumption exceeding 80 mA, it is necessary to provide a control relay.

DOCA0161EN-01 03/2020 53

Reflex Tripping

Introduction

Tripping and Limitation Curves

TeSys GV5 / GV6 devices incorporate the exclusive reflex-tripping system.

This system breaks very high fault currents.

The device is mechanically tripped via a “piston” actuated directly by the short-circuit.

For high short-circuits, this system provides a faster break, thereby ensuring discrimination.

Reflex-tripping curves are exclusively a function of the device rating.

Tripping and Limitation Curves

Limitation Curves

Introduction

The limiting capacity of a device is its aptitude to let through a current, during a short-circuit, that is less than the prospective short-circuit current.

The exceptional limiting capacity of TeSys GV5 / GV6 devices is due to the rotating double-break technique (very rapid natural repulsion of contacts and the appearance of two arc voltages in-series with a very steep wave front).

Ics = 100% Icu

The exceptional limiting capacity of TeSys GV5 / GV6 devices greatly reduces the forces created by faults in devices.

The result is a major increase in breaking performance.

In particular, the service breaking capacity Ics is equal to 100% of Icu.

The Icu value, defined by IEC/EN 60947-2 standard, is guaranteed by tests comprising the following steps:

 Break the circuit three times consecutively with a fault current equal to 100% of Icu  Check that the device continues to function normally, that is:

 It conducts the rated current without abnormal temperature rise.  Protection functions perform within the limits specified by the standard.  Suitability for isolation is not impaired.

Longer Service Life of Electrical Installations

Current-limiting devices greatly reduce the negative effects of short-circuits on installations.

 Thermal effects: Reduced temperature rise in conductors, therefore longer service life for cables.  Mechanical effects: Reduces electrodynamic forces, therefore less risk of electrical contacts, or busbar

being deformed or broken.

 Electromagnetic effects: Reduction in disturbances for measuring devices located near electric circuits.

Economy by Means of Cascading

Cascading is a technique directly derived from current limiting.

Devices with breaking capacities less than the prospective short-circuit current may be installed downstream of a limiting device.

The breaking capacity is reinforced by the limiting capacity of the upstream device.

It follows that substantial savings can be made on downstream equipment and enclosures.

Current and Energy Limiting Curves

The limiting capacity of a device is expressed by two curves which are a function of the prospective shortcircuit current (the current which would flow if no protection devices were installed):

 The actual peak current (limited current)  Thermal stress (A²s), that is, the energy dissipated by the short-circuit in a condition with a resistance

of 1 Ω.

Glossary

AS: Shunt trip

This type of release operates when supplied with current. The shunt (SHT) release provokes circuit breaker opening when it receives a pulse-type or maintained command.

AU: Undervoltage release

This type of release (UVR) operates when the supply voltage drops below the set minimum.

Auxiliary contact (IEC 60947-1)

Contact included in an auxiliary circuit and mechanically operated by the switching device.

Breaking capacity

Value of prospective current that a switching device is capable of breaking at a stated voltage under prescribed conditions of use and behavior. Reference is generally made to the ultimate breaking capacity (Icu) and the service breaking capacity (Ics).

Circuit breaker (IEC 60947-2)

Mechanical switching device, capable of making, carrying, and breaking currents under normal circuit conditions and making, carrying for a specified time and breaking currents under specified abnormal circuit conditions such as those of short-circuits. Circuit breakers are the device of choice for protection against overloads and short-circuits. Circuit breakers can, as is the case for TeSys GV, be suitable for isolation.

Connection terminal

Flat copper surface, linked to the conducting parts of the device, and to which power connections are made using bars, connectors or lugs.

Contactor (IEC 60947-1)

Mechanical switching device having only one position of rest, operated otherwise than by hand, capable of making, carrying and breaking currents under normal circuit conditions including operating overload conditions. A contactor is provided for frequent opening and closing of circuits under load or slight overload conditions. It must be combined and coordinated with a protective device against overloads and shortcircuits, such as a circuit breaker.

Contactor utilization categories (IEC 60947-4-1)

The standard defines four utilization categories, AC1, AC2, AC3 and AC4 depending on the load and the control functions provided by the contactor. The class depends on the current, voltage and power factor, as well as contactor withstand capacity in terms of frequency of operation and endurance.

Degree of protection - IP•• (IEC 60529)

Defines device protection against the penetration of solid objects and liquids, using two digits specified in IEC 60529 standard. Each digit corresponds to a level of protection, where 0 indicates no protection.

 First digit (0 to 6): Protection against penetration of solid foreign objects. 1 corresponds to protection

against objects with a diameter less than 50 mm, 6 corresponds to total protection against dust.

 Second digit (0 to 8): Protection against penetration of liquids (water). 1 corresponds to protection

against falling drops of water (condensation), 8 corresponds to continuous immersion.

The enclosure of TeSys GV motor circuit breakers provides a minimum of IP40 (protection against objects less than 1 mm).

Glossary

Direct rotary handle

This is a control handle for the circuit breaker. It has the same three positions I (ON), O (OFF) and TRIP as the toggle control. It provides IP40 and IK07 protections. It maintains suitability for isolation and offers optional locking using a padlock.

Durability

The term “durability” is used in the standards instead of “endurance” to express the expectancy of the number of operating cycles which can be performed by the equipment before repair or replacement of parts. The term “endurance” is used for specifically defined operational performance.

Electrical durability

With respect to its resistance to electrical wear, equipment is characterized by the number of on-load operating cycles, corresponding to the service conditions given in the relevant product standard, which can be made without replacement.

Electronic trip unit

Trip unit that continuously measures the current flowing through each phase and the neutral if it exists. For MicroLogic, the measurements are provided by built-in current sensors linked to an analog-digital converter with a high sampling frequency. The measurement values are continuously compared by the ASIC to the protection settings. If a setting is overrun, a Mitop release trips the circuit breaker operating mechanism. This type of trip unit offers much better pick-up and delay setting accuracy than thermalmagnetic trip units. It also provides a wider range of protection functions.

Extented rotary handle

Rotary handle with an extended shaft to control devices installed at the rear of switchboards. It has the same characteristics as direct rotary handles. It offers multiple locking possibilities using a padlock or a door interlock.

Failsafe remote tripping

Remote tripping is carried out by an opening mechanism using an AU undervoltage release (UVR) in conjunction with an emergency off button. If power is lost, the protection device opens the circuit breaker.

Ics: Service breaking capacity

Expressed as a percentage of Icu, it provides an indication on the robustness of the device under severe conditions. It is confirmed by a test with one opening and one closing/opening at Ics, followed by a check that the device operates correctly at its rated current.

Icu: Ultimate breaking capacity

Expressed in kA, it indicates the maximum breaking capacity of the circuit breaker. It is confirmed by a test with one opening and one closing/opening at Icu, followed by a check that the circuit is properly isolated. This test ensures user safety.

Ie: Rated operational current

A rated operational current of an equipment is stated by the manufacturer and takes into account the rated operational voltage, the rated frequency, the rated duty, the utilization category and the type of protective enclosure, if appropriate.

Ii: Instantaneous protection

This protection supplements Isd. It provokes instantaneous opening of the device. The pick-up may be adjustable or fixed (built-in). This value is always lower than the contact-repulsion level.

In: Rated current

The rated current corresponds to the current that the device can carry continuously with the contacts closed and without abnormal temperature rise.

Ir: Oervload or thermal protection

Protection function where the adjustable Ir pick-up determines a protection curve similar to the thermalprotection curve (inverse-time curve I

which corresponds to a theoretically infinite tripping time (asymptote) and of the point at 6 Ir at which the tripping time depends on the rating.

t). The curve is generally determined on the basis of the Ir setting

DOCA0161EN-01 03/2020

Isd: Short-time protection with fixed time delay

This protection supplements thermal protection. Short-time protection, but with a fixed time delay. This function is available on MicroLogic 2M. The short-time pick-up Isd is adjustable from approximately 5 to 13 Ir.

Iunbal: Phase-unbalance or phase-loss protection

This protection function steps in if the current values and/or the unbalance in the three phases supplying the motor exceeds tolerances. Currents should be equal and displacement should be one third of a period. Phase-loss is a special case of phase-unbalance.

Maximum breaking time

Maximum time after which breaking is effective, which is when the contacts are separated and the current is completely interrupted.

MCC rotary handle

Handle used for motor control centers and providing IP43 and IK07 protections.

Mechanical durability

With respect to its resistance to mechanical wear, equipment is characterized by the number of no-load operating cycles which can be effected before it becomes necessary to service or replace any mechanical parts.

Glossary

Power loss / Pole resistance

The flow of current through the circuit breaker poles produces Joule-effect losses caused by the resistance of the poles.

Release (IEC 60947-1)

A device which is mechanically connected to a mechanical switching device (for example a circuit breaker), which releases the holding means and permits the opening or the closing of the switching device. For circuit breakers, releases are often integrated in a trip unit.

Safety clearances

When installing a circuit breaker, minimum distances (safety clearances) must be maintained between the device and panels, bars and other protection systems installed nearby. These distances, which depend on the ultimate breaking capacity, are defined by tests carried out in accordance with IEC 60947-2 standard.

SDTAM thermal fault module

Relay module with two static outputs specifically for the motor-protection MicroLogic 2 M trip units. An output, linked to the contactor coil, opens the contactor when an overload or other motor fault occurs, thus avoiding opening of the circuit breaker. The other output stores the opening event in memory.

Spreader

Set of three flat conducting parts made of aluminum. They are screwed to the circuit breaker terminals to increase the pitch between poles.

Starting current

Start-up of a three-phase, asynchronous motor is characterized by:

 A high inrush current, approximately 14 x In for 10 to 15 ms  A starting current, approximately 7.2 x In for 5 to 30 seconds  Return to the rated current after the starting time

Starting time

Time after which the motor ceases to draw the starting current and falls back to the operating current Ir ( ≤ In).

Static output

Output of a relay made up of a thyristor or triac electronic component. The low switching capability means that a power relay is required. This is the case for the SDTAM outputs.

Glossary

Thermal image of the rotor and stator

The thermal image models the thermal behavior of a motor rotor and stator, taking into account temperature rise caused by overloads or successive starts, and the cooling constants. For each motor power rating, the algorithm takes into account a theoretical amount of iron and copper which modifies the cooling constants.

Thermal protection

Protection against over currents following an inverse time curve I permissible temperature rise for the motor. Tripping occurs after a time delay that decreases with increasing current.

Trip class (IEC 60947-4-1)

The trip class determines the trip curve of the thermal protection device for a motor feeder. The standard defines trip classes 5, 10, 20, and 30. These classes are the maximum durations, in seconds, for motor starting with a starting current of 7.2 x Ir, where Ir is the thermal setting indicated on the motor rating plate.

Ue: Rated operational voltage

A value of voltage which, combined with a rated operational current, determines the application of the equipment and to which the relevant tests and the utilisation categories are referred. For multiple equipment, it is generally stated as the voltage between phases. This is the maximum continuous voltage at which the equipment may be used.

Ui: Rated insulation voltage

The rated insulation voltage of an equipment is the value of voltage to which dielectric tests and creepage distances are referred. In no case shall the maximum value of the rated operational voltage exceed that of the rated insulation voltage.

Uimp: Rated impulse withstand voltage

The peak value of an impulse voltage of prescribed form and polarity which the equipment is capable of withstanding without failure under specified conditions of test and to which the values of the clearances are referred. The rated impulse withstand voltage of an equipment shall be equal to or higher than the values stated for the transient over voltages occurring in the circuit in which the equipment is fitted.

t = constant, which defines the maximum
