Product Description

Product Description

 

Working Principle: Explore the intricate operation of this advanced device.

When the current is elevated beyond the safe limit, overloaded, the bimetallic strip inside the breaker expands due to the heating effect caused by the current, and the difference in expansion coefficients between different metal layers leads to bending.

When the bending reaches a critical threshold, it engages the release rod, therebyreleasing the stored spring energy,which in turn separates the contacts effectively,and mechanically trips the breaker,providing immediate interruption of current flow;

When the current isshort-circuited,, a powerful magnetic force from the falling wheel is generated at the base of the electromagnetic coil,attracting the armature to collide decisively with the release rod,ensuring safety and reliability.
