1.14kV 160A Vacuum Contactor - low Voltage Vacuum Contactor, rated voltage 1.14kV, rated current 80A, 125A, 160A
General Description:
Hai Bang 1.14kV 160A Vacuum Contactor is applicable on AC 50-60Hz power systems, rated voltage 1140V, rated current 80A, 125A, 160A. This type of 1140V vacuum contactor is used to directly or remotely connect and disconnect the circuit and frequently control the AC motor, and is suitable for various protection devices (JDB electronic integrated protector, JR9 overcurrent protection device, resistance melting absorption device) to form an electromagnetic starter or explosion-proof magnetic starter. Hai Bang 1.14kV 160A Vacuum Contactor is widely used in metallurgy, underground coal mines, docks and other occasions. The altitude of the environment where the 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.
