1. INTRODUCTION
General Information
The shunt trip (Fig.
provides remote controlled elec-
trical tripping for the circuit breaker. It consists of an inter-
mittent rated solenoid with a tripping plunger and a cutoff
switch attached to a plug-in module. The plug-in module
is mounted in slots in the accessory mounting deck in the
right pole of the circuit breaker. When the solenoid is
energized, the plunger extends and presses against the
trip bar. As the circuit breaker trips, the molded trip bar
rotates and allows the cutoff switch to open, disconnect-
ing power to the solenoid and preventing coil burn out.
Table 1-1 lists application and electrical operating ratings
data for the shunt trip.

The standard wiring configuration for the shunt trip is pig-
tail leads exiting the right side of the cover. An optional
terminal block (Cat No. TBRD) may be mounted to the
right side of the circuit breaker to terminate attachment
ieads. The 18-inch (457.2 mm) long pigtail leads are color
identification; numbered identification labels are
provided for pigtail leads.
This instruction leaflet (IL) gives detailed procedures for
installing the shunt trip.
Note:The shunt trip can be
field installed in
RD
and RDC circuit breakers under UL File E64983.

Before attempting to install the shunt
trip, check that
the catalog number is correct as ordered and that the
rating of the accessory satisfies job requirements.
The shunt trip, shown in kit form in Fig. 2-1, is installed in
the right pole
of
a 3- or 4-pole circuit breaker. To install
the shunt trip, perform the following procedures:
