Overview of VCB ZN63(VS1)-12 630A High Voltage Switchgear Indoor Vacuum Circuit Breaker 630A VCB

VCB ZN63(VS1)-12 630A High Voltage Switchgear Indoor Vacuum Circuit Breaker 630A VCB 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.
