An 11kV vacuum circuit breaker (VCB) is a type of electrical switchgear designed for medium voltage (MV) applications, primarily operating at 11,000 volts. It uses a vacuum as the arc-extinguishing medium, which allows it to interrupt high fault currents with exceptional reliability and minimal maintenance. The vacuum offers superior dielectric strength, ensuring rapid arc quenching, reduced contact erosion, and long service life. Unlike traditional air or oil circuit breakers, vacuum circuit breakers encapsulate contacts in a vacuum interrupter. When the breaker trips, the arc is formed inside this vacuum, where it is swiftly extinguished due to the lack of ionized particles. Application Areas [&hellip;]"}
