Auxiliary Power System Input contactor

The purpose of the Auxiliary Power System Input Contactor is to connect and isolate APS. The operational conditions of the APS input contactor are like those of the line contactor, but with reduced power load. Depending on the control logic, a disconnector can be used instead.

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

  • High breaking capability
  • Heavy duty mechanical operation
  • Wide variety of designs
