ABSTRACT:
A power contactor device includes at least one power relay contained within an electrically insulating plastic housing. Electrical busses carrying current to the relay contacts also serve as a means for removing the heat generated by those contacts and other electrical components within the housing. On the exterior of the housing, the busses have a large surface area and transfer heat through electrically insulating but thermal conducting material, such as alumina or beryllium filled epoxy, to a heat sink. The core of the relay is in metal-to-metal contact with the heat sink.
