Secondary Disconnect (Field installable kit available)
Inputs and outputs to the circuit breaker are wired through
secondary disconnects located
on the top of the breaker. The
plug-style secondary discon-
nects engage mating discon-
nects in the breaker cubicle
when the breaker is in the
TEST or CONNECT position.
Up to 72 dedicated points are
available so that all breaker
accessories can be wired to dedicated disconnect points.
Refer to the breaker wiring diagrams shown on pages 30
and 31 for breaker accessory wiring.

Shunt Trip (Field installable kit
available)
The shunt trip allows remote
electrical tripping of the circuit
breaker. It is usually controlled by
a switch or push button and may
also be used in conjunction with
protective relays for automatic
tripping (the breaker trip units do

not require the use of a shunt trip). The shunt trip coil is rated
for intermittent duty and is supplied with an auxiliary switch
contact that automatically removes control power following a
breaker trip. A shunt trip is always supplied on electrically
operated breakers. A redundant or 2nd shunt trip is available
on all frame size breakers for special control applications. The
second shunt trip occupies the same space as the undervoltage
device. See Table 10.4 for shunt trip operating characteristics.

Spring Charging Motor
The spring charging motor is supplied on all electrically
operated breakers. The breaker closing springs are charged
automatically when control voltage is applied to the breaker.
When the springs are fully charged, a cutoff switch de-ener-
gizes the motor. The closing springs will recharge automati-
cally after the breaker closes unless an external switch con-
