GE Industrial Solutions GERAPID 2607, 4207, 6007, 8007 with arc chutes 1X2, 1X4, 2X2, 2X3, 2X4 - Manual (Page 10)

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

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

•
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.

• 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].

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.

• 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.
