Abstract
A unitary housing structure is provided for an electrical switching device such as a three-phase contactor. The housing includes internal partitions for separating an operator section from contact sections, and for isolating phase sections from one another. The partitions are contiguous with one another and with side walls of the housing, inhibiting plasma flow within the housing cavities. The housing is made of a thermoplastic material which is molded as a single piece. The thermoplastic may be partially protected from plasma and arcs by shields within the phase sections, such as splitter plate supports.
