1.14kV 2500A Vacuum Contactor - low Voltage Vacuum Contactor, rated voltage 1140V, rated current 1600-2500A
General Description:
Hai Bang 1.14kV 2500A Vacuum Contactor – Type CKJ3-1.14J(D)/D-1600~2500 is applicable on AC 50-60Hz power systems, rated voltage 1140V, rated current 1600-2500A. This type of 1.14kV Vacuum Contactor is used to Directly or remotely connect and disconnect the rotor circuit of the winding motor. Hai Bang 1.14kV 2500A Vacuum Contactor is suitable for electrical control occasions requiring high current control under AC-2 usage category, and is widely used in phase advancers, soft-start cabinets, and high-frequency electric furnaces. The altitude of the environment where this type of low voltage Vacuum Contactor is used does not exceed 1000 meters above sea level.
Please refer to the categories for other types of 1.14kV Vacuum Contactors with other values of rated current.
