The GVC20 series vacuum contactors are suitable for AC 50-60Hz power network systems with main circuit rated currents of 630A, 800A, and 1000A. They are designed for remote switching, frequent starting, and control of AC motors, transformers, and capacitor banks. This series of vacuum contactor features a fully enclosed design, a elegant appearance, stable and reliable performance, maintenance-free operation, and a long service life. They are the ideal replacement for old-fashioned vacuum contactor.
