Product Description

 

Product Description

 

working principle:


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, extinguishing the arc.
