What is a Vacuum circuit breaker?

A Vacuum Circuit Breaker (VCB) is a type of switchgear used to interrupt electrical current in high-voltage power systems. It extinguishes arcs within a vacuum chamber, offering superior arc extinguishing performance, low maintenance, and long lifespan. Utilizing vacuum insulation allows for compact designs, making it widely applicable in industrial facilities, substations, and railway systems. Its eco-friendly nature, as it does not use oil or gas, is another key advantage.

Application of Vacuum circuit breaker

✅Power Transmission and Distribution
Used in substations to protect against short circuits and overloads.
✅Railway Power Systems
Ensures safe current interruption during train operations, preventing overcurrents.
✅Industrial Equipment Protection
Safeguards high-voltage equipment and motors in factories.
✅Renewable Energy Systems
Stabilizes power supply in wind and solar energy installations.
