Abstract: An electrical switching apparatus includes a transductor circuit that senses a direct current between at least one input terminal and at least one output terminal and outputs an alternating current proportional to the direct current between the input terminal and the output terminal. The electrical switching apparatus also includes an alternating current electronic trip circuit configured to control pairs of separable contacts to separate based on the alternating current output from the transductor circuit. The alternating current electronic trip circuit includes a rectifier circuit, an interface circuit, and a processor structured to output a control signal to control a trip actuator to cause an operating mechanism to separate the plurality of pairs of separable contacts.
