Overview of Indoor ZN63 Series Withdrawable Vacuum Circuit Breaker For Various Metal Armored Center Cabinets

Indoor ZN63 Series Withdrawable Vacuum Circuit Breaker For Various Metal Armored Center Cabinets 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.
