Reliable Mingtuo Vacuum Circuit Breaker 73*72*80 for Electrical Safety Vcb

Product Description

 
Reliable Mingtuo Vacuum Circuit Breaker 73*72*80 for Electrical Safety Vcb

Working Principle:


When an electrical anomaly such as an overloaded circuit or a short-circuit current occurs, this sophisticated system comes into action. The current sensor swiftly transmits the collected current signals directly to the high-tech intelligent controller, ensuring real-time monitoring.

The intelligent controller then promptly issues a
trip command to energize the tripping coil, which in turn releases the stored power of the energy-stored spring within the operating mechanism, ensuring maximum efficiency.

This carefully orchestrated sequence causes the contacts to rapidly separate,
swiftly extinguishing the arc, thus protecting your electrical systems with precision and reliability.
