Product Description

Product Description

 

Working Principle:

When the current is overloaded, the bimetallic strip expands due to the heating caused by the current, and the difference in expansion coefficients between different metal layers leads to bending.

When the bending reaches the threshold, it pushes the release rod, whichreleases the spring energy, separates the contacts, and mechanically trips the circuit;

When the current isshort-circuited, a magnetic force from the falling wheel is generated at the base of the electromagnetic coil, attracting the armature to collide with the release rod.
