Features

 

VJ12 vacuum circuit breaker adopts optimized modular mechanism, with a long life of 30,000 times, simple and reliable. The primary circuit uses a solid sealed pole structure. The arc extinguishing chamber and conductive components are cast into a solid sealed pole and contact by AGP process. Low contact resistance, fast arc recovery speed, more environmentally friendly and safer. The insulation of the main conductive loop is stable and reliable. The product is easy to install and maintain, can basically meet the needs of industrial and mining enterprises, and basically achieves maintenance-free. The high prototype product is suitable for 4,000 meters high altitude, and the capacitor dedicated switch is suitable for frequent switching of capacitive loads.
