The GVC40 series high-performance vacuum contactors are designed for AC 50-60Hz power network systems with main circuit voltages ranging from 1.14kV to 2.5kV and main circuit rated currents from 1000A to 2000A. They are suitable for applications that require remote switching, frequent starting, and control of AC motors, transformers, and capacitor banks.
This series of vacuum contactors features a fully enclosed structure, large capacity for heat dissipation, and a combination of high-performance components. They offer advantages such as stable and reliable mechanical characteristics, long service life, and maintenance-free operation. They are particularly suitable for use as main switches in high-power wind power and photovoltaic inverters. The GVC40 series provides excellent cost-effectiveness and is an ideal alternative to imported products.
