The NV2-12 Permanent Magnet Actuator Vacuum Circuit Breaker developed by CHINT passed the national type test with 120 thousand times mechanical life of the CB, marking CHINT as the first company in the industry to pass this test in China.
The circuit breaker is a newly launched product aiming at middle and high-end market. By using the stable single coil modular magnetic actuator, it is featured with fewer components and high reliability, lowering the starting current effectively and reducing mechanical vibration of the CB so as to extend the electric life significantly.
After it hit the market, the product has acquired recognition from end users. Some of them have already been applied in mines and metallurgy plants.
