Claims

[Scope of utility model registration request]

In a circuit breaker operating device provided on a door of the switchboard for opening and closing a circuit breaker mounted on a panel inside the switchboard from the outside of the switchboard, a base of the operating device fixed to the surface of the door of the switchboard is provided. A return spring is pivoted inwardly and cooperates with a portion of the operating handle of the operating device, and is pressed by the portion of the operating handle when the operating handle is rotated to a position where the circuit breaker is opened. The head of a screw pin for opening the switchboard is configured to rotate about the pivot shaft as a fulcrum against force, and is arranged at its free end inside the base so that the door of the switchboard can be opened by operating it from the outside. A circuit breaker operating device characterized in that a tongue-like body is provided so as to cover a through hole formed in the base so as to be visible to the outside.
