ABSTRACT:
A rotary control device for a circuit breaker having a front plate having an opening through which a crank pin extends, the crank pin being pivotal between first and second positions, the rotary control device including a housing and a rotary handle mounted on the housing, the rotary handle being rotatable between first and second positions corresponding to the first and second positions of the crank pin. A coupling mechanism is provided for mechanically coupling the rotary handle to the crank pin when the housing is mounted on the front plate of the circuit breaker, the connecting device preventing mounting of the rotary control device on the circuit breaker when the rotary handle and the crank pin are not in the same position, that is, are not both in the first position or both in the second position. The first and second positions may correspond to open and closed positions of the circuit breaker, for example.
