Description

1.14kV 400A Vacuum Contactor - low Voltage Vacuum Contactor, rated voltage 1140V, rated current 400A

General Description:

Hai Bang low Voltage Vacuum Contactor, 1.14kV 400A Vacuum Contactor – Type CKJ5-400A/1140V is applicable on AC 50-60Hz power systems, rated voltage 1140V, rated current 400A. This type of low voltage 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. 1.14kV 400A Vacuum Contactor is widely used in metallurgy, underground coal mines, docks and other occasions. The altitude of the environment where the 1.14kV Vacuum contactor is used does not exceed 2000 meters above sea level.

Please refer to the categories for other types of 1.14kV Vacuum Contactors with other values of rated current.
