ABSTRACT:
A receptacle having a pocket accommodating the insertion of an insulative printed circuit card is equipped with one set of contacts disposed to one side of the pocket and individually electrically connected to a breaker static trip unit. Two additional sets of contacts, disposed to the other side of the pocket, are respectively connected to different secondary winding taps of each of a plurality of phase current transformers. Plural pairs of electrically interconnected conductive strips are printed on opposite sides of the card in positions to connect the contacts of the one set individually to the contacts of either one of the two additional sets, depending upon the orientation of the card when inserted in the pocket.
