Description

1.14kV 800A Vacuum Contactor - low Voltage Vacuum Contactor, rated voltage 1.14kV, rated current 630-800A

General Description:

Hai Bang low Voltage Vacuum Contactor – Type CKJ3-1.14D/D-630~800 is applicable on AC 50-60Hz power systems, rated voltage 1140V, rated current 630-800A. This type of 1.14kV vacuum contactor is used to directly or remotely connect and disconnect the main circuit and frequently control AC motors, transformers and other electrical control occasions. Haibang 1.14kV 800A Vacuum Contactor is widely used in petroleum, coal mine explosion-proof equipment and other occasions. The altitude of the environment where the 1.14kV 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.
