Abstract: An electromagnetic operator includes first and second coils wound coaxially. An armature partially surrounds the coils for channeling flux during energization of the coils. The armature may be formed of a bent plate and secured to a ferromagnetic support. A control circuit applies energizing signals to the coils during operation. Both coils are energized during an initial phase of operation. One of the coils is subsequently released or de-energized automatically. A timing circuit removes current from the second coil after a variable time period. The time period may be a function of the configuration of the timing circuit, such as an RC time constant, and of the energizing signal.

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.
