Product Description

Product Description

 

Working Principle:

The Efficient Mingtuo Circuit Breaker Switch is ingeniously designed to intervene when overloaded. The bimetallic strip cleverly expands due to the generated heat from the excess current. The distinct expansion coefficients of the metals involved cause a precise and reliable bending.

Upon reaching a critical bending point, the movement activates the release rod, which thenharnesses the spring energy toeffectivelyseparate the electrical contacts,and mechanically trips the breaker; thus ensuring safety.

In the event of a short circuit,an impressive magnetic force from the falling wheel emerges at the base of the electromagnetic coil,swiftly pulling the armature to engage the release rod. This dual-action protection ensures the utmost reliability of your electrical systems.
