Section 6 – Accessories Description

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 Castell, Ronis, Kirk and Profalux
for installation between related, separate circuit breakers (Table
6.10).
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
six single-pole changeover contacts for local or remote
electrical indication of the circuit breaker status:
CONNECTED, TEST and DISCONNECTED. The DISCONNECTED
position is indicated only when minimum isolating distances
between contacts on both the main and auxiliary circuits
have been achieved. 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 (Tables 6.11 and 6.12).

Mechanical Interlocks (Cable/Rod)

Available for fixed and drawout circuit breakers, these units
enable the direct interlocking of EntelliGuard G circuit
breakers, either mounted side-by-side or stacked. The
interlocking mechanisms are connected by a specially designed
cable or rod in a 1 from 2, 1 from 3, and 2 from 3
configuration, and any mix of current ratings/pole
configurations can be accommodated. Standard cable lengths
available: 1.0 m, 1.6 m, 2.0 m, 2.5 m, 3.0 m, 3.5 m and 4.0 m.
(Please contact our technical customer service department if
longer length is required.)
Mechanical interlocks can be fitted to electrical systems as
shown in Table 6.13 and can link 2 and/or 3 circuit
breakers. Any nominal rating, frame size, number of poles
Catalog Number
or type (fixed pattern or draw-out) can be interlocked
