Q5. Vccb work principle an
Ans. 
Vccb stands for Vacuum Circuit Breaker. It works on the principle of extinguishing the arc in a vacuum environment.
• VCCB uses a vacuum as the arc quenching medium instead of air or oil.

• When the contacts of the breaker open, the arc is drawn into the vacuum and extinguished.

• This method ensures faster arc extinction and reduces the risk of fire hazards.

• VCCBs are commonly used in high voltage applications where quick and r
