This series of vacuum contactor is a new product develop according to market demand, this series of high-quality vacuum switch select military factories, structural metal frame insulated bracket structure, have the advantage of solid and strong, stable and reliable performance, the main circuit center distance of 190mm, stroke distraction ability for 12kv below, altitudes greater than 2000-3000 m below the plateau and Hyperion for remote making and analysis and frequent start and control of AC motors, transformers and capacitors, and other occasions. We have two kinds: electromagnetic institutions and permanent magnet institutions
