GE Industrial Solutions Power Break II Motor Operator User Manual
Power break, Introduction, Remote operation
Introduction
The Motor Operator Mechanism, shown in Figure 1, can
be installed in 800–4000 A frame Power Break® II circuit
breakers. It provides a means of remotely or
automatically charging the springs that close the breaker.
Table 1 lists the catalog numbers and corresponding
electrical data for the available models. Note that the
Remote Close and Shunt Trip accessories are not
included with the Motor Operator Mechanism; they must
be ordered separately.
Figure 1. Motor Operator Mechanism.
Remote Operation
The circuit breaker closing springs can be charged
remotely by shorting terminals 17 and 35 on the terminal
block on the right side of the breaker, with a push button
or similar device, for a minimum of five seconds. Power
for the Motor Operator must also be applied to terminals
18 and 36, as shown in the wiring diagram in Figure 6.
Automatic Operation
Connect terminals 17 and 35 on the terminal block on
the right side of the breaker with a jumper wire. The
Motor Operator will automatically recharge the breaker
closing springs whenever the breaker closes.
