The VHCR series composite apparatus is an indoor high-voltage switchgear that consists of a model VHC vacuum contactor and high-voltage current limiting fuse.Used in electrical systems with rated voltage of 12kV, this model features low cost, long life, and high frequency of operation.This composite apparatus has been used widely in control motors, transformers, capacitors, load circuits for power plants, industrial and mining facilities, and general power lines. It is especially suitable for locations where frequent operation is requiredWith a module superposed layout, VHC vacuum contactors may be used separately or in combination with other components. Additionally, these products may be used in fixed type, movable type and non-fuse type (shorted conductive rod) constructions.Meeting the requirements of GB1808 and IEC60470 standards, this product also complies with GB16926 stipulations. The outline and installation dimensions are consistent with those of the VH4 model vacuum breaker produced by our company, and mounts conveniently in model GZS1 switch cabinets.Specifications:1) Module type construction, can be easily combined2) Current of fused mass: 6.3 - 200A (optional)3) Suitable for both frequent and high frequency operation4) With mechanical and electric interlocking guarantee5) Long life, maintenance free6) Extremely low operating over-voltage
