Coaches power supply contactor

Coaches Power Supply Contactors reside on locomotives and supply the power distribution line for HVAC, heaters, and auxiliary converters. These contactors operate at 3kV/1.5kV on DC systems and at 1kV (supplied by a secondary winding of the traction transformer) on AC systems.

In case of extreme environmental conditions, this application requires a frequent short-circuit making current. We offer a wide variety of designs to fit most installation requirements.

  • High making and breaking capability
  • Suitable for heavy-duty electrical and mechanical operating conditions
