Working Principle of Vacuum Circuit Breaker. The Vacuum Circuit Breaker operates on the principle of utilizing a vacuum as the arc extinguishing medium. Unlike traditional circuit breakers that use air, oil, or SF6 gas, VCBs create a vacuum environment between the contacts. When the contacts are separated during a fault, an arc is initiated.
When the contacts of the circuit breaker are separated in the vacuum (Vacuum pressure in the vacuum bottle is 10-7 to 10-5), an arc is produced between the fixed and moving contacts by the ionisation of metal vapours of contacts.However, the arc is quickly extinguished because of the metallic vapours on the contacts surface, electrons …
