Product Description

Indoor Vacuum Circuit Breaker 12kv Vcb

Product Description

 
Indoor Vacuum Circuit Breaker 12kv Vcb

Working Principle:


When an overloaded circuit or short-circuit current occurs, the current sensor diligently transmits the collected current signals to the intelligent controller.

The intelligent controller promptly issues a
trip command to energize the tripping coil, seamlessly releasing the energy-stored spring in the operating mechanism.

This expertly causes the contacts to rapidly separate,
swiftly extinguishing the arc.
