Vacuum circuit breakers (VCBs) act as essential safety and control switches in electrical power networks, rapidly extinguishing electrical arcs inside a hermetically sealed vacuum chamber to protect equipment from overloads and system faults.
Vacuum Circuit Breaker (VCB)
A Vacuum Circuit Breaker is a medium-voltage switching and protection device that uses a vacuum to extinguish electrical arcs. It provides fast, reliable circuit interruption and helps protect electrical equipment from faults.
