ABB Medium Voltage MV Vacuum Contactors

ABB VSC IEC Indoor Vacuum Contactors 7.2kV-12kV


ABB VSC medium voltage contactors are suitable for operating in AC and are normally used to control electrical equipment requiring a high number of hourly operations, up to 12 kV, 400 A.

ABB VSC IEC Indoor Vacuum Contactors     

The ABB contactors can operate in particularly difficult environments. They are suitable for control and protection of high voltage motors, transformers, power factor correction banks, switching systems.

Fitted with suitable fuses, ABB medium voltage vacuum contactors can be used in circuits with fault levels up to 1000 MVA.
