Claims

[Scope of utility model registration request]

(1) An operating handle for turning the circuit breaker ON and OFF, and an opening through which the operating handle is inserted with a margin, and the operating handle is turned on by the spring force of the closing spring.
an operating plate that is always pressed in the N operating direction; a handle holder that has an opening through which the operating handle is inserted with a margin and that is constantly pushed in the OFF operating direction of the operating handle by the spring force of an auxiliary spring; a cam driven by an electric motor to move the operating plate in the OFF operating direction of the operating handle against the spring force of the closing spring;
When the operating handle is in the ON position, one end surface of the opening of the operating plate is brought into contact with the operating handle, and when the operating handle is in the OFF position, the other end surface of the opening of the handle receiver is brought into contact with the operating handle. A circuit breaker operating device configured to be brought into contact with the circuit breaker.

(2) A long hole is bored in the handle holder along the moving direction of the operation plate, and a stepped pin is inserted into the long hole to slidably attach the handle holder to the operation plate. An operating device for a circuit breaker according to claim (1) of the utility model registration.

(3) The auxiliary spring is suspended between the handle holder and the operation plate.Claim (1) or (2) of the Utility Model Registration Claim
Operating device for the circuit breaker described in Section 1.
