ELECTRICAL SWITCHING APPARATUS INCLUDING TRANSDUCTOR CIRCUIT AND ALTERNATING CURRENT ELECTRONIC TRIP CIRCUIT

摘要

An electrical switching apparatus (1) includes a transductor circuit (100) 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 (200) 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 (202), an interface circuit (208), and a processor (216) structured to output a control signal to control a trip actuator (416) to cause an operating mechanism (414) to separate the plurality of pairs of separable contacts.
