Power Break® II Circuit Breaker Accessories
Shunt Trip and Shunt Trip with Lockout
Introduction
The Shunt Trip and Shunt Trip with Lockout accessories,
shown in Figures 1 and 2, can be installed in 800-4000
ampere frame Power Break®II circuit breakers. These
accessories allow the breaker to be tripped electrically from a
remote location.
In addition to providing a trip signal to the breaker, the
Shunt Trip accessories can be set up to interact with other
Power Break II accessories, when used with a MicroVersaTrip
PlusTM or MicroVersaTrip PM™ Trip Unit. DIP switches on
the rear of the breaker Trip Unit can configure the Shunt Trip
accessories to activate a Bell Alarm-Alarm Only accessory or
a Bell Alarm with Lockout accessory when a shunt trip
occurs. The Accessory
describes how this can be done. If the breaker is equipped
with a Power+™ Trip Unit, it is configured so that only
protection trips will activate a Bell Alarm­Alarm Only or Bell
Alarm with Lockout.

Operation
Apply control voltage to terminals 31 and 32 of the terminal
strip on the right side of the breaker to trip the circuit
breaker. The Shunt Trip will cause the circuit breaker to trip
when the control voltage is greater than 75% of the rated de
voltage or 55% of the rated ac voltage. Control power to the
Shunt Trip must be removed before the breaker can be
closed. Control power to the Shunt Trip with Lockout must
be removed for a minimum of 0.25 second before the breaker
can be closed.
