33 KV VACUUM CIRCUIT BREAKER
A 33 kV Vacuum Circuit Breaker (VCB) is an electrical switching device used in medium-voltage power distribution networks to safely control, monitor, and interrupt electrical currents under normal and fault conditions. It is the industry standard for systems operating between 11 kV and 33 kV due to its rapid arc extinction, environmental safety, and virtually maintenance-free operational life
