Product Description

Product Description

 

Working Principle:

In the sophisticated realm of electrical protection, the overloaded circuitactivates a bimetallic strip, a marvel of precision engineering, which elegantly expands as heat accumulates due to the excessive current. This meticulous design leverages the different expansion rates of the composite metals, prompting a controlled bending motionthat initiates a responsive action.

As it reaches a critical bending point,the system expertly engages the release rod, whichutilizes stored spring energyto effortlessly separate the contactsand commence a mechanical tripin a seamless sequence.

In the scenario of ashort circuit,an intense magnetic force from the falling wheel emerges with precision, propelled by the dynamics of the electromagnetic coil,pulling the armature to engage, thereby triggering a chain reaction with the release rodto ensure maximum safety control.
