Overview of Source Outdoor Vacuum Circuit Breaker Primary and Secondary Fuse Complete Set of Column Switches

Source Outdoor Vacuum Circuit Breaker Primary and Secondary Fuse Complete Set of Column Switches 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.
