Abstract: An electronic trip unit having a number of trip unit settings includes: a first input member; a second input member; a multi-position selector configured to select one of plurality of positions corresponding to values of the trip unit settings; a plurality of indicators each corresponding to one of the plurality of trip unit settings; and a processor having a routine, wherein the routine of the processor is structured to, in response to actuation of the first input member, increment a ring counter value and selectively activate one of the indicators corresponding to the ring counter value; and wherein the routine of the processor is further structured to, in response to actuation of the second input member, set a value of the trip unit setting corresponding to the activated indicator based on the selected position of the multi-position selector.

Abstract: An electrical switching apparatus includes a transductor circuit that senses a direct current between an input terminal and an output terminal and outputs an alternating current proportional to the direct current. The electrical switching apparatus also includes a current sensor configured to sense an alternating current component of the direct current. The electrical switching apparatus further includes an alternating current electronic trip circuit including an arc fault detection circuit configured to detect an arc fault based on the sensed alternating current component. The alternating current electronic trip circuit is also configured to control pairs of separable contacts to trip open based on the alternating current output from the transductor circuit or the detected arc fault. The electrical switching apparatus also includes a power supply structured to provide direct current power to the alternating current electronic trip circuit.
