動機制御回路。 A limit switch that detects the completion of energy storage of a closing spring of a spring operation mechanism in a power circuit breaker, a field control electromagnetic contactor and an armature control electromagnetic contactor whose opening/closing operations are controlled by this limit switch, and these electric contactors. A dynamic braking circuit is connected in parallel to the limit switch through a contact point of the electromagnetic contactor for controlling the armature, and is configured by a contact point and is attached to the armature circuit and field circuit of the DC motor for closing spring energy storage. 1. A motor control circuit for a power circuit breaker, comprising a CR series circuit for absorbing surges.
