General Description:
Hai Bang High Voltage Horizontal Vacuum Contactor is applicable on AC 50-60Hz power systems, rated voltage 7.2kV and 12kV, 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. The Horizontal 7.2kV Vacuum Contactor is used in power grid reactive power compensation, chemical industry, metallurgy, water supply and drainage treatment, coal mine equipment and other occasions. The altitude of the environment where the horizontal Vacuum Contactor Unit is used does not exceed 1000 meters above sea level.
