ABSTRACT:
An electrical switching apparatus comprises: a first terminal; a second terminal; separable contacts electrically connected between the first terminal and the second terminal; an operating mechanism structured to open and close the separable contacts; and an arc fault trip circuit cooperating with the operating mechanism and structured to trip open the separable contacts responsive to an arc fault condition. An inductor is electrically connected in series between the first terminal and the second terminal. A capacitor includes a first lead electrically connected between the inductor and the second terminal, and a second lead electrically connected to a ground or neutral conductor. The inductor and the capacitor are structured to cooperate with a power circuit impedance downstream of the second terminal to form a filter trap circuit.
