Hai Bang Single Phase AC Vacuum Contactors –Type CKJ1-3.6D/D3200 is suitable for AC 50~60Hz power systems, main circuit rated voltage 1140V-3.6kV, rated current 3200A. This type of Single Phase Vacuum Contactor is mainly used as a grounding switch when a single-phase ground fault occurs. Single Phase Vacuum Contactors are used in electrical occasions that require single-phase control. The altitude of the environment where the 3.6kV Single Phase Vacuum Contactor is used does not exceed 1000 meters above sea level.
