Coaches power supply contactor

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
