Durable Mingtuo Vacuum Circuit Breaker 73*72*80 Made in China Vcb

Product Description

 
Durable Mingtuo Vacuum Circuit Breaker 73*72*80 Made in China Vcb

Working Principle: Discover the intricate operation behind the durability and efficiency of our circuit breaker.


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

The intelligent controller then issues a
trip command to energize the tripping coil, which releases the energy-stored spring in the operating mechanism.

This causes the contacts to rapidly separate, ensuring the swift and safe
extinguishment of the arc. Embrace the synergy of cutting-edge technology and superior safety with the Mingtuo Vacuum Circuit Breaker, engineered to safeguard your electrical infrastructure.
