Overview of VD4 VCB Drawer Type Indoor 15KV 17.5KV Vacuum Circuit Breaker Used for High Voltage Distribution Line KYN 28

VD4 VCB Drawer Type Indoor 15KV 17.5KV Vacuum Circuit Breaker Used for High Voltage Distribution Line KYN 28 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.
