VI For Circuit Breaker
Vacuum Interrupters for Circuit Breakers are used in circuit breakers to shut down, carry and open the current under normal circuit conditions and to shut down, carry and open the current under abnormal circuit conditions within a specified period of time. Hongfa vacuum interrupter chamber adopts one time sealing and arranging process, which is characterized by high vacuum degree, good insulation strength, strong opening and breaking ability, low circuit resistance, high level of voltage resistance and long service life.
