General Description:
Hai Bang High Voltage Vacuum Contactor is applicable on AC 50-60Hz power systems, rated voltage up to 7.2 kV, rated current 160A, 250A, 400A, 630A. This type of high voltage vacuum contactor is used to directly or remotely connect and disconnect the main circuit and frequently control capacitive loads, AC motors, transformers and other electrical equipment. This type of 7.2kV vacuum contator is widely used in power grid reactive power compensation, chemical industry, metallurgy, water supply and drainage treatment, underground coal mine equipment and other occasions. The altitude of the environment where the Vacuum Contactor is used does not exceed 1000 meters above sea level.
