DC/DC converter input contactor

The purpose of the DC/DC converter input contactor is to connect and isolate DC/DC converter from DC Link. 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
  • Suitable for heavy-duty mechanical operating conditions
