Vacuum Contactor-Fuse Combination 7.2kV / 12kV
General Description:
Hai Bang Vacuum Contactor-Fuse Combination – Type
HCR-7.2J(D)Y/D315-50T and HCR-12J(D)Y/D200-50T are applicable on AC
50-60Hz power systems, rated voltage 7.2kV and 12kV, rated current
315A, 200A. It 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. It can be used for
frequent starting of motors and frequent switching of transformers
and capacitors. Vacuum Contactor-Fuse Combination 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 Vacuum Contactor-Fuse Combination 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.
