GE GM01120A Circuit Breaker Motor Operator

Core Performance & Industrial Application

The GE GM01120A is a motorized operating mechanism (motor operator) designed for EG frame molded case circuit breakers.

It drives the breaker closing and opening action by motor power, enabling remote electrical operation instead of manual handle switching.

It runs on 110-130V AC control supply at 50/60 Hz and mounts directly on the EG frame breaker body.

It is used in automatic power distribution cabinets where breaker switching requires remote or automatic control.

It is a discontinued genuine GE spare part, widely kept as replacement for legacy Series G EG frame breaker installations.
