Product Description

Product Description

 

Working Principle:

When the current experiences an overload situation, overloaded, the bimetallic strip within the system expands due to the heating effect caused by excessive current flow, and the distinct expansion coefficients between the various metal layers result in bending.

Once this bending achieves the critical threshold, it activates the release rod, therebyreleasing the stored spring energy, separating the contacts, and mechanically tripping the device;

In the event of a short circuit,a powerful magnetic force is generated by the falling wheel at the base of the electromagnetic coil, which pulls the armature to engage and collide with the release rod,thereby ensuring prompt and safe functionality.
