Product Description

Product Description

 

Working Principle:

In the sophisticated operation of the Premium Quality MCCB Molded Case Circuit Breaker by Mingtuo, when an overloadoccurs, the bimetallic strip undergoes expansion as a result of heat generated by the excess current, and the variance in expansion coefficients among the metal layers induces bending.

Upon reaching a critical point, the bending forceengages the release rod, thereby releasing the stored spring energy, which forces the contacts apart, and initiates a mechanical trip;

In scenarios of a short circuit, an intense magnetic force from the falling wheel emerges at the base of the electromagnetic coil, drawing the armature to contact with the release rod.
