Vacuum Circuit Breaker (VCB) is a specialized type of circuit breaker that utilizes a vacuum or empty space to quench the arc or interrupt the circuit. Due to their low maintenance requirements, VCBs
are ideal for medium voltage applications, and are commonly utilized in voltage ranges from 11 KV to 33 KV.
