Description

General Description:

Hai Bang 7.2kV Vacuum Contactor-Fuse Combination Unit – Type HCR-7.2J(D)Y/D315-50T is applicable on AC 50-60Hz power systems and rated voltage 7.2kV, rated current 315A. The rated voltage of the typeHCR-12J(D)Y/D200-50T is 12kV, and its rated current is 200A. They can be installed in the switch cabinet to form an F-C circuit and used in conjunction with a comprehensive protector. The Vacuum Contactor Unit combines a high-voltage fuse capable of breaking a wide range of short-circuit fault currents with a vacuum contactor that can be frequently operated. The Vacuum Contactor-Fuse Combination unit can be used for frequent starting of motors and frequent switching of transformers and capacitors. Vacuum Contactor-Fuse Combination unit is widely used in power systems such as power plants, chemicals, coal mines, metallurgy, ports and wharfs. It can be used by power plants and industrial and mining enterprises to switch on and off AC high-voltage motors, transformers, induction furnaces and other loads, and has the function of short-circuit protection. The trolley at the bottom of the 7.2kV Vacuum Contactor-Fuse Combination unit can be easily moved out of the control cabinet. The altitude of the environment where the product is used does not exceed 1000 meters above sea level.
