Vacuum Circuit Breaker (VCB) – Principle, Construction and …
VCB stands for Vacuum Circuit Breaker. In vacuum circuit breakers, the vacuum is used as the arc quenching medium. Vacuum offers the highest insulating strength. So it has far superior arc quenching properties than any other medium (oil in oil CB, SF6 in SF6 circuit breaker).
Vacuum Circuit Breaker (VCB) – Construction and Working
A vacuum circuit breaker (VCB) is a type of circuit breaker that uses a vacuum as the arc quenching medium to interrupt the flow of electrical current in a circuit. Vacuum is a superior dielectric and the best medium for arc extinction in circuit breakers.
VCB Rating Chart | Explanation and Example | Wira Electrical
The current rating for a Vacuum Circuit Breaker (VCB) can be up to 3 kA. A VCB works by interrupting the arc that exists in a vacuum bottle. The voltage rating for a VCB can be up to 35 kV.
