Product Description

Product Description

 

Working Principle:

When the current is overloaded, the bimetallic strip begins to expand due to the heating effect induced by the current flow, and the differing expansion coefficients among the distinct metal layers result in bending.

When the bending achieves the critical threshold, it actuates the release rod, whichutilizes the stored spring energy toeffectively separate the contacts, thereby mechanically trippingthe breaker;

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