Product Description

Product Description

 

Working Principle:

When the current is excessively heavy,the ingenious bimetallic strip undergoes expansion due to the intense heating induced by the current. The distinct expansion coefficients of the metal layers result in a precise bending action.

Once this bending achieves the pre-set threshold,it triggers the release rod, which relegantly releases stored spring energy, promptly separating the contactsand inducing a mechanical trip;

In the event of a short circuit,a powerful magnetic force from the falling wheel is generated at the base of the dynamic electromagnetic coil, swiftly drawing the armature to engage with the release rod,ensuring optimal protection.
