Product Description

Product Description

 

Working Principle: A Masterpiece of Engineering and Safety

When the current is persistently drawing more than its designated capacity, overloaded,the bimetallic strip, ingeniously designed, expands due to the incremental heating, caused by the current's flow. This heating, coupled with the disparate expansion coefficients between the meticulously chosen metal layers, induces a precise bendingmovement.

When this bending reaches a critical threshold,it artfully propels the release rod, whichinstantly releases the stored spring energy,thus swiftly separating the contactsand mechanically tripping the breaker; providing unmatched safety.

When the current experiences a suddenshort circuit,a dynamic falling wheel magnetic force is instantaneously generated at the base of the electromagnetic coil,creating a powerful attraction to the armature, which forcefully collides with the release rod,ensuring rapid response and protection.
