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!
2010-06-07 S47183e rev.03 Design and specifications are subject to change without notice 5

2.2 Installation

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].
Fig. 2 Termination for grounding wire

2.3 Usage

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 auxiliary-
tripping 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

3.1 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 high-
power 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.

Fig. 4 Modular construction overview

3.2 Components and accessories

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;
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”, de-
clutches 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.
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,
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].

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.
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 19-
4c]. 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.
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. 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.

With a correctly designed interlock in an enclosure, FT
provides safety-tripping function. During withdrawal
operation of the trolley, the breaker is tripped BEFORE its
main terminals disconnect from the mains.
Fig. 10b Positioning of the forced tripping pin
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. 11a Closing operation by using hand lever
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
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.
Fig. 14 OCT trip target
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. 16 Solenoid closing drive and control box
After closing attempt, the switch-in mechanism is
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 signal-
processing 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.

3.2.13 Electronic control system
All the control PCBs are installed in control box [Fig. 18].
Starting from the left, these are:
Fig. 18 Control box with control units
(1) NEKO control unit [Fig. 19-1] (Code 12) – internal
control unit with capacitor bank. Releases firing signal for
ED coil (-X2 :10/:11) and provides indication of the
capacitors charging (-X3 :6/:7). NEKO control unit also
blocks the firing signal until C-bank is fully charged
(~15 sec).
WARNING: NEKO unit requires a high quality firing signal.
Be sure, that voltage level is between 6 V…24 V DC and
there are no short spikes on signal (<3 ms). This might
lead to major defect of the NEKO control unit!
Fig. 19-1 NEKO control unit
(2) Internal voltage converter (Code 8) - converts
external supply voltage (-X3 :4/:5) to the internal
24 V DC. Required by controls (except for the drive
supply).
Fig. 19-2 Voltage converter 110 V/24 V DC.

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.
