Overview
This unit frame type high-voltage vacuum contactor was developed in the early 1980s. It is widely used as an indoor device in power systems with AC 50Hz, rated working voltage of 12kV, and rated working current up to 630A. It is used to frequently open and close the load circuit of AC high-voltage motors and transformer electrical control equipment. After reducing the capacity, it can be used for capacitive load circuits.
