Abstract
A battery disconnect includes a housing, battery and load terminals, separable contacts electrically connected between the battery and load terminals, an operating mechanism structured to open and close the contacts, and a manual operator cooperating with the operating mechanism to open and close the contacts. A current sensor is structured to sense current flowing between the battery and load terminals. A circuit cooperates with the current sensor and the operating mechanism to trip open the contacts responsive to arc fault, overload and short circuit conditions associated with the sensed current. The circuit includes a first input structured to receive a remote on/off signal and a second input structured to receive an inhibit signal. The circuit cooperates with the operating mechanism to open and close the contacts responsive to the on/off signal, and to inhibit detection of the arc fault, overload and short circuit conditions responsive to the inhibit signal.
