An operator is provided for a molded-case circuit breaker of the type in a motor controller where the circuit breaker is removably mounted on a pan brace which is held in place by a pan latch. The operator mounts on the breaker for opening and closing the breaker and for providing three interlocks. One interlock prevents withdrawal or insertion of the breaker with the operator handle in the 'on' position. A second interlock prohibits closing or opening the control door except when the handle is off and a third interlock locks the operator handle in 'off' position.
