Introduction
Shunt Trip (Extended Range):
A device designed to switch the Power Circuit
Breaker OFF remotely. When energized a Shunt
Release instantaneously activates the circuit
breaker mechanism ensuring a rapid
disconnection of the main contacts. Shunt trips
are suitable for a continuous power supply and
are designed to be used as a closure prevention
device when energized. Two Shunt trips can be
mounted in each Power Circuit Breaker. The
device is available as factory mounted
component or as a field mountable device. It is an
easy-to-fit, clip-on unit, with simple plug-in
connectors to the Secondary Disconnect Block.
