Capacitor 3 Phase Vacuum Contactor
Hai Bang High Voltage Vacuum Contactor – Type JCZ53 Phase vacuum contactor applicable on AC 50-60Hz power systems, rated voltage up to 7.2kV, rated current 160A, 250A, 400A, 630A. This type of Capacitor 3 phase 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 Capacitor 3 phase vacuum contactor is widely used in power grid reactive power compensation. The altitude of the environment where the vacuum contactor is used does not exceed 1000 meters above sea level.
