Abstract (en)

[origin: WO9921201A1] A hermetically sealed contactor (10) of the magnetic blowout type is provided utilizing a novel arc chute design (14). The fins (60) of the arc chute (14) include an angled leading edge (67) and a tapered body (38) for slowing and confining the arc in the chute (14) until extinction. The housing (16) is back pressurized with a highly thermally conductive gas to assist in removing heat from the arc, permitting the use of a smaller and simpler contactor (10) arrangement, while maintaining the performance realized in larger devices.
