Product Description

Product Description

 

Working Principle:

When the current flows beyond the required limits, overloading the circuit,the innovative bimetallic strip expands, thanks to the significant heat generated by the excessive current. The distinct thermal expansion coefficients of the layered metals result in a graceful bending action.

Once this bending crosses the critical threshold,it activates the release rod, harnessing the storedspring energy to swiftlyseparate the contacts, ensuring that thecircuit is disrupted and mechanically trippedto prevent further damage;

In the event of ashort circuit,a powerful magnetic force from the falling wheel emerges at the base of the electromagnetic coil,drawing the armature to dramatically collide with the sturdy release rod,ensuring immediate action.
