Auxiliary Power System Output contactor

The purpose of the Auxiliary Power System Output Contactor is to connect and isolate the auxiliary load, starting from APS. The operational conditions of the APS output contactor strongly depend on the type of connected load. Typically, AC loads require three or four pole contactors.

We offer a wide variety of designs to fit most installation requirements
