ABSTRACT:
A contactor of the high-voltage type utilizing an arc chute and aligned magnetic pole pieces for urging an arc into the chute for quenching. A pair of rigid bus bars extend upon either side of the arc chute assembly, and are projected along the edges of the pole piece to supplement the arc displacement capability of the pole pieces, particularly at higher current values.
