VCB Vacuum Circuit Breaker 630A 1250 A 11kV 12kV 24 KV 33KV

Vacuum Circuit Breaker (VCB) is an electrical switching device that uses a vacuum as the interrupting medium to extinguish the electric arc when a fault occurs in the electrical circuit. VCBs are typically used in medium-voltage applications (up to several thousand volts) and are often used in power generation, transmission, and distribution systems.
