GE Industrial Solutions EntelliGuard E Network Interlock for 3200-5000 Ampere - Manual

Introduction
The Network Interlock provides a means of locking out a
circuit breaker to coordinate its operation with other
circuit breakers in the distribution network. When
activated by the EntelliGuard Messenger™, the Network
Interlock prevents the circuit breaker from closing. When
the EntelliGuard Messenger issues a reset signal, the
circuit breaker can be closed either remotely or locally.
The Network Interlock accessory includes a manual reset
lever to reset the device in the absence of a signal from the
EntelliGuard Messenger.
The Network Interlock contains a microswitch to remotely
indicate the state of the lockout and thus whether or not
the circuit breaker can be closed. The Network Interlock
kit (EGNTWKLFKIT) consists of the Network Interlock
module (EGNTWKLFRPLC), mounting bracket, trip
paddle, manual reset assembly, and hardware, as
illustrated in Figure 1. The catalog information for large
frame Network Interlock kit and replacement module is
listed in Table 1.
Note: The Network Interlock kit is for use with
EntelliGuard circuit breakers installed in Entellisys™ Low
Voltage Switchgear only.
Note: A Bell Alarm with Lockout and Network Interlock
cannot be installed concurrently in a circuit breaker.

Operation
The Network Interlock consists of a set solenoid, a reset
solenoid, and a status switch. The device connections to
the secondary disconnect are shown in Figure 2. When
voltage is applied across the set solenoid, the device locks
out the circuit breaker. Conversely, when voltage is applied
to the reset solenoid or when the manual reset knob is
pulled, the Network Interlock allows the circuit breaker to
re - close.
