1. Warnings

Warnings:
During operation, electrical equipment carries dangerous voltages. In addition, circuit breaker emits hot, ionized gases when switching currents, especially short circuit currents.
Installing, commissioning, maintaining, changing or refitting of this equipment must be carried out only by qualified and suitably trained personnel and under strict observation of national and international applicable safety regulations.
During their operation, circuit breakers must be equipped with appropriately fitted covers, e.g. in suitable enclosures or panel boards. Safety distances must be preserved. Suitably trained service personnel shall only carry out certain works.
Non-compliance with these warnings may result in death, and/or severe physical damage and extensive damage to equipment.
Prior to carrying out maintenance, inspection or checks, the circuit breaker must be open, the both terminals must be grounded, the circuit breaker must be switched off and the control plugs removed.
Manual activation of the breaker while energized is forbidden. Manual activation must only be used for maintenance and inspection purposes, when breaker power is off and grounded.
The circuit breaker consists of high energy moving components. Do not touch the circuit breaker while it is being switched ON (closing) or OFF (opening). There is a high risk of major injury.
The control circuits may include capacitor banks, which can be charged with dangerous voltages. Work on this section must be carried out carefully.

2. General usage conditions

2.1 Transportation and storing

The breaker is transported on wooden palette. It is fixed by shrunken plastic film. A cardboard box covers the breaker on the palette. Truck, railway, airplane and ship transport is possible. In case of sea transport, special protection against salty and humid environment is provided.
The circuit breaker must always be transported to the installation site vertically and fully packed. The packaging protects the device against damage and dust; it should only be removed prior to installation.
If the packaging is damaged, the breaker and the arc chute must be inspected for damage. Ensure that all packaging materials have been carefully removed prior to breaker installation.
For handling the unpacked breaker use canvas slings and
position them below the closing drive (a) and below the lower terminal (b) [Fig. 1].
Fig. 1 Handling the breaker
WARNING: Breaker and arc chute must be transported separately. Never handle the breaker with arc chute installed at!
Take care that the bottom isolation plate of the unpacked breaker is not damaged during handling. Do not push the breaker back and forth on any rough surface.
The breaker’s weight, including arc chute is listed in Table 1, page 13. Arc chute’s weight is ca. 30 kG (66 lb) for “1x_” type, and ca. 60 kG (132 lb) for “2x_” type
WARNING:
Store in original packaging!
Do not store outdoors!
Use protection against crush and blow!
Do not store the breaker in a damp area!
Storing temperature-range –25 °C…+55 °C!

2.2 Installation

2.3 Usage

2.2.1 Operational environment
The breaker, as delivered, is IP00 (NEMA 1) protected. It is intended to work in indoor applications, without pollutions, with non-conductive dust, protected against high humidity and condensation. Low conductivity dust deposit due to frequent condensation of humidity is acceptable. General environmental conditions refer to EN 50123-1 - annex B, and IEC 60947, class PD3.
The breaker can operate at rated current within ambient temperature range of –5 °C to +40 °C (23 to 104 °F). Maximum operating ambient temperature is +55 °C (130 °F) with continuous current derated by 10 %.
The breaker can operate at altitude up to 2000 m (~6500 ft) without derating.
The breaker shall not be subjected to strong vibrations. Maximum vibrations of 0.5 g per 30 sec in vertical and horizontal directions are allowed.
Air shall be clean and its relative humidity shall be not
more than 50 % r.h. at the maximum temperature of +40 °C (104 °F). Relative humidity may be higher if the temperatures are lower, for example, 90 %r.h. at +20 °C (68 °F). Slight condensation might occur during variations of temperature
2.2.2 Installation and interfaces
The lower and upper main terminals (Code 4) must be connected directly to the main cables or bus bars.
WARNING: The breaker must only be used in an upright operation position with the arc chute in place and fully secured.
After arc chute installation check for tightness both connections to the arc runners. See drawing 49, item 3.
The safety distances as listed in section 5.1 shall be maintained to grounded or insulated parts. Suitable measures must be taken to protect personnel from arcs.
Strong, external magnetic fields, caused by improperly located supply conductors or stray fields from other devices, can lead to a shift of the trip setting thresholds. This may result in premature tripping, or no tripping at all during low-level short circuit current events. This has to be accounted for when installing and operating the device with shielding added if appropriate.
The control wires must be connected to the control terminals (Code 19), as shown in the schematic circuit diagrams in section 4. The protective grounding wire must be connected at the marked contact [Fig. 2].
2.3.1 Supply and load
In accordance with its type, the breaker has been designed for the current and voltage listed in Table 1, section 3.3.
During continuous operation, breaker must only be loaded up to its maximum rated current. Load currents in excess of breaker nameplate rating are allowable for brief periods. Refer to the short time currents listed in Table 1.
Do not exceed the rated operating voltage shown on the breaker’s nameplate.
Supply voltage for the drive and the auxiliary-tripping devices (Code 8) shall be within the specified control voltage range. Maximum current values for the auxiliary­tripping devices are listed in Table 2a.
WARNING: Plugging in or unplugging of the auxiliary connectors (-X2 :1/:2) (-X3 :4/:5) is only allowed with disconnected primary (mains) and secondary voltages.
2.3.2 Adjusting the over current release
OCT is an over-current tripping release (Code 7), which trips and releases the breaker in case of overload or short circuit currents. This is an instantaneous and direct acting device.
If equipped with an adjustable OCT, the response threshold can be easily adjusted [Fig.3], by turning the adjustment nut 1 with a SW6 hexagon wrench 2.
The adjustment must only be carried out after the breaker has been disconnected from the main circuit. For fixed installations breaker’s main terminals shall be grounded.
Turning the adjustment screw clockwise increases the trip threshold, turning the screw counter-clockwise decreases the tripping threshold.
Align the arrow and the desired marking 3, to perform adjustment.

3. Technical information

3.2 Components and accessories

3.1 Introduction

Gerapid is a high-speed DC circuit breaker. This is a single-pole DC breaker, primarily designed for use in railway power distribution systems with operating currents up to 8000 A (Code 1) and operating voltages up to 3600 V (Code 2). Additional applications are special industrial plants such as electrolysis, mining or steel mills.
Gerapid breaker has a very high interruption capacity combined with a current limiting characteristic. The arc chute works on the basis of an asbestos-free arc splitting principle.
A wide variety of accessories and spares are available for maintenance, repair, or as a possible enhancement.
Use the catalogue coding system described in section 7.1 to configure the breaker. Each rating, option or accessory has own code.
Closing of the circuit breaker is performed through a high­power solenoid drive (Code 3).
During inspections, opening and closing may be carried out by means of a hand lever (Code 16), which is mounted onto the armature of the closing drive.
Overload tripping and release is obtained directly by means of the OCT release (Code 7), or optionally by ED impulse release (Code 12). Indirect remote tripping can be achieved by means of a shunt trip, or optionally by a zero voltage release (Code 11).
Gerapid breakers have a compact and enclosed construction [Fig. 4]. Gerapid is IP 00 protected. All parts are mounted on thick-walled, non-breakable and fireproof insulation panels.
3.2.1 Contact system
All Gerapid breakers are equipped with a two-stage contact system [Fig. 5], consisting of a main contact and an arcing contact. With this proven design, the main contact is not subjected to any appreciable wear or tear.
The main contact is made of a silver composite material. The arcing contact and link braid are made of copper and can be easily replaced.
The flexible bend is linked to the arcing contact by means of very tight braid.
Fig. 5 Two types of the contact system
3.2.2 Arc chute (Code 2)
Compact and modular design of the arc system requires no additional magnetic support and allows small safety distances with high breaking capacity.
Because of the compact dimensions, these breakers can be installed in extremely small enclosures (from 500 mm;

Fig. 4 Modular construction overview

6 Design and specifications are subject to change without notice S47183e rev.03 2010-06-07
1.65 ft) and offers a cost-effective solution for replacements.
An adaptor [Fig.43] is used to mount the various arc chutes for different operating voltages on the breakers.
The arc chutes consist of a highly durable, arc-proof material, in which the arc plates have been integrated.
The arc plates split the arc into partial arcs and increase the arcing voltage by multiplying the anode and cathode voltage drop. Because of their high heat capacity, the plates and arc chute walls absorb a large amount of the arc’s energy.
3.2.3 Mechanism
The Gerapid is equipped with a modular designed mechanism, which is wear-resistant and nearly maintenance-free. This mechanism ensures an extended electrical and mechanical endurance of the breaker as well as a high level of safety under all operation conditions.
Breaker can operate 20 000 cycles when opened by the shunt trip or zero voltage release, and 1 000 operations by means of ED impulse coil or OCT releases.
This mechanism is mechanically latched in the CLOSED position. The principle of a mechanically latched mechanism offers a big advantage compared to often used electro magnet holding system. No auxiliary control power source is required to keep breaker closed.
The mechanism is provided with two tripping latches [Fig. 6]. First latch, called “slow latch”, is used for opening under normal conditions, like actuation of shunt trip or zero-voltage release. The second one, “quick latch”, de­clutches the main contact arm from the mechanism and opens the contacts with an extremely short delay. This is used when interrupting short-circuit or overloads. All safety releases operate onto “quick latch” latch.
Different main springs are used in mechanisms for different breaker frames. Therefore mechanisms cannot be exchange between breakers of different frame.
which releases the quick latch in the mechanism. The latch and contacts are opened immediately.
The response threshold can be easily adjusted by turning the adjustment nut with a SW6 hexagon wrench. The available ranges are described in the table below. Other ranges might be possible on request.
When supplied with the optional transparent side protection covers (Code 15), a fixed mounted insulated knob is provided to enable OCT adjustment [Fig. 16].

Fig. 6 Latching and tripping system
3.2.4 Over current release (Code 7)
The OCT release is a magnet with two magnetic circuits, optimizing the twin magnetic field principle [Fig. 7]. This technology ensures equally fast tripping in both current directions. This system does not require an auxiliary control voltage to operate. It is a direct acting and instantaneous tripping device.
The OCT consists of the holding circuit [6], the movable armature [3] and the tripping circuit [7]. The holding and the tripping magnetic circuits are both excited by load current [1]. Until the static overload release’s response threshold has been reached, the armature [3] is held in position by the holding flux (ΦH) [2] and the counter spring’s force [4]. Once the load current exceeds the set static response threshold, the attraction flux (ΦA) [2] takes over and rapidly pulls down the flexible armature [3]. During this operation, the armature hits the seesaw,

3.2.5 ED impulse coil release (Code 12)
ED impulse release requires an external protective relay for monitoring a current increase. This relay must be provided and installed by the customer.
If a fault occurs, an external relay signal wired into the capacitors’ control unit (internal NEKO or external C-bank), causes NEKO unit to discharge its energy into ED coil [Fig. 8]. The coil trips the breaker’s quick latch and opens breaker’s contacts in less 3ms.
ED impulse release is an optional accessory. Complete set consists of ED coil and electronic control unit with C-bank called NEKO. The external release signal shall be 6 V to 24 V DC, and shall be connected at terminals (-X2 :10 / :11) in standard wiring scheme.
Customer supplied capacitor trip unit may be used. Rated voltage of 300 V and capacity of 2 000 µF is required. In this case only ED coil will be installed in the breaker.
WARNING: Firing signal voltage level is between 6 V and 24 V. There should be no spikes on the signal of duration less 3 ms. This can lead to defect of the NEKO board!
WARNING: Maximum duration of the firing signal must not exceed ~1 sec. Longer signal can lead to NEKO overheat! It is recommended to use an auxiliary contact in serial connection with firing circuit (-X2 :10/:11). It will automatically cut off the firing circuit after breaker opening.
The UVR [Fig. 9] is used for remote actuation and, in combination with an internal electronic control, for voltage control.
The UVR releases at voltage interruption or supply voltage drop below 20 V. In these cases UVR trips the breaker. It is therefore possible to use this device in combination with the electronic trip unit for voltage monitoring, where an unintended re-start of machines after a temporary voltage breakdown is to be prevented.
The UVR is intended for continuous operation. Its rated power is 10 W.
Due to its operational mode, the UVR is a self-monitoring device, i.e. when the breaker is tripped upon a break of the pilot wire (EMERGENCY-OFF principle).
NOTE: Manual closing of the breaker with ST installed, while pushbutton OPEN is pressed and control power applied, might lead to ST coil’s overheating and damage.
Fig. 8 ED impulse coil with seesaw interface
3.2.6 Auxiliary tripping devices (Code 11)
The breaker can be equipped with either a shunt trip (ST) or a zero voltage release (UVR). It is not possible to have both devices installed in the same breaker. Both devices are interchangeable.
In standard configuration, internal voltage converter (Code 8) transforms external voltage into 24 V DC, which is required by ST or UVR. Both devices are tripped by a potential free contact connected as shown in section 4.2.
Optionally, ST can be connected directly to external voltage. In this case extinguish capacitors and diode is used to improve switching of the shunt trip’s coil [Fig 19­4c]. Double winding shunt trip is available with this option for 110/125/220 V DC external control supply.
Optionally, it’s possible to supply both devices directly to external 24 V DC ( ± 5%). In this case the release signal for ST shall not be longer 100 ms.
The ST is used for remote actuation. It is designed for short time operation with max. duty cycle of 9 %. ST’s supply is connected through auxiliary contacts, which cut off supply voltage after opening. This protects ST against overheating.
Fig. 9 Zero voltage release
3.2.7 Forced tripping release (Code 13)
Optionally, the forced tripping release (FT) can be installed in the breaker [Fig. 10a]. This unit mechanically trips the breaker, by pressing the pin against the bottom plate. Force required to trip the breaker is about 30 N (~7 ft-lb). The tripping pin position is as on Fig. 10b.

3.2.8 Lever for manual operating (Code 16)
Optionally, a hand lever for manual closing and opening operation during maintenance is available. This tool must not be use while breaker is energized!
To close the contacts, install hand lever on the drive’s rod, and pull it out smoothly until latches snap [Fig. 11a].
To open the contacts, install the tool into the ring and push it hard against the drive’s rod until breaker opens [Fig. 11b].
WARNING: Manual closing and opening – only during maintenance!
Fig. 11b Opening operation by using hand lever
Alternative manual closing and opening operation is possible by rotating the main shaft of the breaker mechanism, which is accessible from the side. Use 10 mm hexagon-socket wrench to OPEN/CLOSE [Fig. 11c].
WARNING: Pay attention to control rotation speed of the shaft during manual opening. Impede the wrench to avoid hitting it to the ground, which may lead to a hand injury.

3.2.9 Auxiliary switch (Code 9)
Standard breaker can be equipped with 3, 5 or 10 isolated, form C, invertible auxiliary contacts (1 NO/NC each). The movable main arm activates the contacts.
The contacts are wired to 15-pin control terminals: -X4 and -X5, with 5 switches to each terminal [Fig. 21].
Conventional thermal current Ith=10 A. Maximum electrical ratings for switches are 1 A/230 V for AC15. For DC13 are 0.5 A/110 V and 0.3 A/220 V.
Fig. 12 Auxiliary contacts layout in control box
3.2.10 Indicators
Optionally, the circuit breaker can be equipped with following indicators:
POSITION INDICATOR (Code 14) - mounted at the front of the closing drive. Mechanically switched by means of drive’s rod. Indicates position of the main contacts. “O” – means contacts are open “I” – means contacts are closed
ARC CHUTE INDICATOR (Code 17) – a potential free, NO contact mounted on the sidewall. Locks electrically the closing drive when arc chute is not installed on [Fig. 15].
Fig. 15 Arc chute indicator
3.2.11 Solenoid closing drive (Code 3)
A high power solenoid is used to perform fast closing operation. This drive is mounted at the front of the breaker and is encased in a grounded casing [Fig. 16].
Closing drive is supplied independently from other controls (-X2 :1/:2), directly from external power source. Voltage level must be defined at order placement. Rated power, depends on breaker type, but is between 1.8 kW and 2.6 kW.
CLOSING command is enable by external potential free contact at (-X2 :4/:5). Signal duration shall be ~300 ms.
The closing drive system always includes a self-interrupt control circuit (SU PCB). This circuit enables short activation with a time of ~150 ms. SU switches power to the solenoid and automatically disconnects it after ~400 ms.
The SU unit also prevents repeated drive closing, due to an existing and continuous short circuit conditions and provides an “anti-pumping” safety feature.
Fig. 13 Position indicator
OC TRIP TARGET (Code 10) – a potential free, NO contact mounted at the top of the OCT [Fig. 14]. Provides a signal when OCT trips.

electrically blocked for approximately 8 sec. Lock time increases to 14 sec, if internal C-bank (NEKO) is present. This prevents premature closing following a short circuit.
3.2.12 Current measurement system (Code 6)
The SEL current measurement system consists of the sensing component (1) and signal-processing unit (2) [Fig.17]. SEL sensor is integrated into a specially shaped upper terminal of the breaker and is connected by a shielded cable to the signal-processing unit. SEL control unit is placed in the control-box [Fig. 18].
Fig. 17 SEL current measurement system
SEL may be used for recording DC currents in selected measurement ranges of 6 kA or 12 kA. Measurement of rated current values and of the current rise may now be made directly at the breaker.
The sensor includes Hall-probes and delivers a proportional signal-output to the SEL control. The signal­processing unit transforms input signal, into standard output signals shown in the table below.
The outputs are insulated from the main voltage. The insulation withstands voltages up to 4 kV RMS and up to 40 kV in peak.
Two versions are available. Standard model (T35) for ambient temperature –5 °C…+35 °C and the model for higher temperature (T55) –5 °C…+55 °C.
More details can be found in separate instruction for SEL usage.

1) These relays are part of internal closing stop circuit. It is a 24 V DC closed circuit, through all PCBs in the box, except SEL. Serial connection of all relays is realized through connections ( :5/:6) in each PCB. This circuit provides priority of a tripping signal over a closing signal. Additionally it prevents from closing the internal supply 24 V DC lost at UVR PCB or NEKO PCB.
