Claims

[Claims for Utility Model Registration] A clamp for operating the handle of a circuit breaker, a cam that operates the clamp, an operating handle connected to the cam and operating the handle of the circuit breaker;
A lock lever that engages with the cam when the door is opened to prevent the operation handle from being closed; and a lock lever that engages with the lock lever when the door is closed to lock the door in the closed position and prevent the operation handle from being closed when the door is closed. In the operating device for a circuit breaker, which is equipped with a lock fitting that acts on the lock lever, the lock lever is moved to the door lock release position after the release operation, regardless of whether the circuit breaker is in the open or closed state. and by operating the operating handle in the closing direction when the circuit breaker is in the open state, and by operating the operating handle in the opening direction when the circuit breaker is in the closed state. An operating device for a circuit breaker, comprising a holding mechanism that automatically releases the holding state.
