Power Break® II Circuit Breaker Accessories
Shunt Trip and Shunt Trip with Lockout 480& 600Vac
Introduction
The Shunt Trip and Shunt Trip with Lockout accessories,
shown in Figure1, 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 Plus or
MicroVersaTripPM 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 Lock out accessory when a shunt trip occurs. The
Accessory Configuration section below 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
Alarm ­ Alarm Only or Bell Alarm with Lockout.
The catalog numbers for the Shunt Trip and Shunt Trip with
Lockout for 480 and 600Vac are listed in Table 1. Voltage and
current ratings in Table1 are given at the input of the
transformer. The voltage and current ratings of the input to
the accessory are equal to that of the 120Vac version of the
accessory. Table 2 Iists these ratings.
Operation
Apply control voltage to the primary of the supplied step-
down transformer. The secondary of the transformer is
connected to terminals 31 and 32 of the terminal strip on the
right side of the breaker.
WARNING: 480 Vac and 600 Vac Shunt Trip accessories
must be used with the supplied step-down transformer
AVERTISSEMENT: Les modules de déclenchement shunt
480 Vac et 600 Vac doivent être utilisés avec le
transformateur abaisseur de tension qui est fourni.
The Shunt Trip or Shunt Trip with Lockout will cause the
circuit breaker to trip when the control voltage is greater
than 55% of the rated ac value. 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.
