Features of vacuum Circuit  breaker: Small contact stroke, small size, light weight, low operating power, quick, short arcing time. Isolation performance of the contacts is good after arc-extinguishing, failure capability is better around breaking area; slight combustion loss when breaking the current of contactors, long life, low noise;Used in high frequency operation.

Features of permanent magnet vacuum  Circuit breakers: This breaker adopts bistable permanent magnet mechanism, the integrated design of mechanical manual closing mechanism and mechanical manual opening mechanism. Permanent magnet mechanism opening is combined with spring opening, the distribution of opening speed is more ideal. Compared with spring operating breaker, movable units are less, significantly improving reliability and life, they are ideal replacement for spring operating breaker.
