Circuit Breaker - Key Interlock Facility

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. Circuit breakers accept ready-to-fit
interlocking device kits such as Kirk for installation between
related, separate circuit breakers (Table 6.7).

NOTE: Locks and keys are not supplied by GE. Please order
separately from your local supplier.

Carriage Position Switch (TOC)
Available as an option for mounting within the base of the
cassette/substructure, the carriage position switch provides
changeover contacts for electrical indication of the circuit
breaker status: CONNECTED & TEST. This option is in addition
to the mechanical indicators, which are fitted as standard.
When installed, the carriage switch is IP2X protected and
includes wiring to a terminal block located on the left side of
the cassette (Table 6.8).

Bell Alarm with Lockout
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 (Table 6.9).

Charging Spring Status Indicator
Factory-installed on the motor, this auxiliary switch indicates
that the circuit breaker is charged and is standard with the
spring-charging motor.

Secondary Disconnects (Factory-installed/Field
Installable)
Inputs and outputs to the circuit breaker are wired through
secondary disconnects located on the top 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 39 points are available so
that all breaker accessories can be wired to dedicated
disconnect points. See Table 6.10 for block location and
Table 6.11 for secondary disconnect parts.
