Abstract
A contactor safety combination includes two contactors and a mechanical interlocking module coupled between them. It is possible to use conventional contactors of any size, i.e., even high-capacity loads are switchable with the contactor safety combination of the present invention. At the same time, this design approach dispenses with a third contactor conventionally used for the interlocking.
