Greegoo’s self-developed low and medium-voltage Fast Vacuum Contactors and Fast Vacuum Circuit Breakers (VCB) feature ultra-fast switching with a 5ms opening or closing time. Utilizing vacuum arc-extinguishing technology, these units are eco-friendly, safe, and offer superior insulation and voltage resistance.
The product line covers voltages of 2.5kV, 3.6KV, 12kV and currents from 400A to 2500A, with the VCB achieving a breaking capacity of 31.5kA. Designed for high mechanical and electrical endurance with low maintenance, we also support customized parameters for specific needs of high speed vacuum contactors. These fast vacuum switches are widely used in power distribution, renewable energy integration, industrial automation, rail transit, and flexible AC transmission systems (FACTS). They enable high-frequency switching and rapid short-circuit fault clearing, serving as critical components for MMC valves, high-power motors, and capacitor banks.
