7.2kV MKVC Vacuum Contactor for High Voltage Motor Protection with 300,000 Mechanical Life

View Product Details

Product Overview

The MKVC vacuum contactor represents a new-generation medium-voltage vacuum switch element series developed using advanced domestic and international technology. Engineered with identical dimensions to A-B-B's VC contactor, this product enables installation in minimum 650mm mid-mounted switchgear configurations.

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.

Protection and control of high-voltage motors, transformers, and capacitor banks
Induction furnace control systems
Industrial applications in thermal power plants, metallurgy, petrochemicals, and mining plants
Marine and shipping industry electrical systems

Configuration Options

The GPVC vacuum contactor offers three distinct holding configurations to meet various operational requirements:

Electrical holding mechanism
Mechanical self-holding system
Permanent magnet holding technology

Control electromagnets facilitate closing operations through the operating mechanism, while opening operations are achieved via reliable opening springs.

Technical Specifications

MKVC vacuum contactors are available in two voltage grades with corresponding fuse compatibility:

MKVC 7 - Rated voltage 3.6~7.2kV, current range 6A to 315A
MKVC 12 - Rated voltage 12kV, current range 6A to 160A
