御回路。[Claims for Utility Model Registration] It has a spring energy storage electric motor that is activated when an electromagnetic contactor for a motor is operated, and when the electric motor is driven, it stores energy in a closing spring via an operating mechanism and also uses a circuit breaker electrode. In the motor control circuit of a power circuit breaker that closes the circuit breaker, an operating mechanism for storing energy in the circuit closing spring,
rotated by the drive of the spring energy storage electric motor;
It is composed of an eccentric cam provided with a detection mark at a predetermined portion, and an operating rod having one end pivotally attached to the peripheral edge of the cam and the other end attached to the movable end of the circuit closing spring, Provided is an optical sensor device comprising a sensing portion provided at a position where the detection mark exists when the closing spring completes energy storage, and a switch that is turned off when the detection mark is detected, A motor control circuit for a power circuit breaker, characterized in that a switch of an optical sensor device and the electromagnetic contactor for the motor are connected in series between positive and negative terminals of a control power source.
