Technical Examples

The present invention provides an electrical isolation apparatus having independently controllable contactors. The isolation apparatus includes a contactor for each phase or pole of an electrical device as well as each phase or pole of a load. Each contactor is constructed so that each includes multiple contact assemblies that may be independently controlled to open and close. 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 in the contactor assembly. Additionally, the contactors are constructed and controlled such that a single line side contactor and a single load contactor open simultaneously when an open circuit condition is desired.
