Description

7.2kV Vacuum Contactor And Fuse Combination Apparatus Medium Voltage MV&HV Contactors Vacuum Circuit Breakers

MKVC vacuum contactor is a new-generation medium-voltage vacuum switch element series product developed with advanced domestic and international technology. The MKVC product shares identical dimensions with A-B-B's VC contactor, enabling installation in minimum 650mm mid-mounted switchgear.
Applications
The MKVC vacuum contactor operates in conjunction with high-voltage fuses capable of breaking wide-range short-circuit fault currents. Designed for AC systems with voltages of 3.6~12kV and frequencies of 50Hz/60Hz requiring extensive opening and closing operation cycles, it is particularly suitable for frequent switching applications. Widely used for protection and control of electrical equipment including high-voltage motors, transformers, capacitor banks, induction furnaces, and more in thermal power plants, metallurgy, petrochemicals, mining plants, and shipping industries.
Configuration Options
The GPVC vacuum contactor offers three configurations: electrical holding, mechanical self-holding, and permanent magnet holding. Control electromagnets facilitate closing operations through the operating mechanism, while opening operations are achieved via opening springs.
Technical Specifications
MKVC vacuum contactors are available in two voltage grades with corresponding fuse compatibility:
