ABSTRACT:
A motor control circuit controls operation of a motor for making or breaking one or more pairs of contacts of a power switching device such as a circuit breaker. The motor control circuit includes a logic circuit responsive to a control input signal and an enable signal for producing an active signal state when both the control signal and the enable signal are present, and for producing an inactive logic signal state when either of the control signal and the enable signal is not present. A switching control signal producing circuit is responsive to said active state of the logic signal for producing a switching control signal for operating the motor for a predetermined time interval sufficient to perform one of opening and closing of the one or more pairs of contacts.
