2500A Single Phase Vacuum Contactor - High Voltage Vacuum Contactor
Single Phase 2500A Vacuum Contactor - Single phase High Voltage Vacuum Contactor, rated voltage 7.2kV, 12kV, rated current 1600A~2500A
General Description:
Hai Bang Single Phase 2500A Vacuum Contactor – Type JCZ1-12D/D1600~2500 is suitable for AC 50~60Hz power systems, main circuit rated voltage 7.2kV, 12kV, rated current 1600A~2500A. This type of Single Phase Vacuum Contactor is mainly used as a grounding switch when a single-phase ground fault occurs. Haibang Single Phase 2500A Vacuum Contactor could be used in arc suppression cabinets and electrical occasions that require single-phase control. The altitude of the environment where the Single Phase Vacuum Contactor is used does not exceed 1000 meters above sea level (Type G does not exceed 2500 meters).
We have another type of 12kV(7.2kV) Single Phase Vacuum Contactor, whose rated current are 160A, 250A, 400A, 630A. Please refer to the categories for more information.
We also have Plateau type of 12kV(7.2kV) Single Phase Vacuum Contactor with patent design, which could operate safely and stably within an altitude of 5000m above sea level. Please refer to the categories for more information.
