Abstract
A modular asynchronous contactor assembly includes a contactor for each phase or pole of an electrical device. The contactor assembly is applicable as both a switching device and an isolation or load protection device. As such, each contactor is constructed so that each includes multiple contact assemblies. Moreover, the contactors within a single contactor assembly or housing can be independently controlled so that the contacts of one contactor can be opened without opening the contacts of the other contactors of the contactor assembly.
