Vacuum Circuit Breaker (VCB)

VCB stands for Vacuum Circuit Breaker, a type of circuit breaker where the arc quenching takes place in a vacuum medium. VCBs are widely used in medium and high-voltage applications due to their reliable performance, durability, and low maintenance requirements. They are designed to protect electrical circuits and equipment from overcurrent, short circuits, and other faults by interrupting the flow of electricity. In VCBs, the contacts are enclosed in a vacuum chamber. When the contacts open, the arc formed is quickly extinguished as the vacuum provides high dielectric strength, effectively interrupting the circuit. This ensures minimal wear and tear on the contacts and enhances the breaker’s lifespan. VCBs are environmentally friendly, as they do not use harmful gases or oils for arc quenching.
