Description:
Vacuum circuit breaker has 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.
