Motor Operator

The unique motor/gearbox unit is specially
designed to operate with the full range of
EntelliGuard G Circuit Breakers. It is easily fitted
with three heavy-duty bolts. After a breaker close
operation, the unit automatically recharges the
spring and makes it ready for immediate open
and re-close should the need arise. High speed
recharging ensures that the springs are fully
charged within approximately three seconds
following a release. All electrically operated (EO)
ANSI/UL breakers are equipped with “Spring
Charged, Power Rated” contacts for status
indication.
