Description/ Specification of Vacuum Circuit Breaker / Vacuum Contactor

A vacuum circuit breaker (VCB) is an important device in electrical power systems that is meant to interrupt or close electrical circuits safely and effectively. VCBs are different from conventional circuit breakers that operate on air or other gases because they use a vacuum as the arc-quenching medium. This has several benefits. To start with, the lack of gas rules out the possibility of gas explosions or leaks, and hence VCBs are safe and ecologically friendly. VCBs are extremely effective in arc extinguishing, which are electric discharges occurring when a circuit is broken. The insulating nature of the vacuum helps in the quick extinguishing of the arc, causing little wear and tear to the circuit breaker and less need for maintenance. This efficiency also allows VCBs to support high current and voltage levels, which makes them suitable for medium- to high-voltage applications in power distribution systems.
