Overview of VS1(ZN63) 12kv /24kv 630a/1250a Vacuum Circuit Breaker High Voltage Vcb for Switchgear

VS1(ZN63) 12kv /24kv 630a/1250a Vacuum Circuit Breaker High Voltage Vcb for Switchgear is a type of circuit breaker where the arc quenching medium is a high vacuum. Unlike older breakers that used air, oil, or SF6 gas to extinguish the electrical arc, a VCB utilizes the superior dielectric properties of a vacuum to rapidly extinguish the arc when the contacts separate, thereby interrupting the current flow and protecting the electrical system.
