Vacuum Circuit Breaker (VCB) – Principle, Construction and Working
When the contacts of the breaker are opened in the vacuum (10-7 to 10-5 torr), an arc is produced between the contacts by the ionization of metal vapors of contacts.. However, the arc is quickly extinguished because the metallic vapors, electrons, and ions produced during arc rapidly condense on the surfaces of the circuit breaker contacts, resulting in a quick …
