Product Description

Product Description

 

Working Principle:

In the sophisticated world of electrical protection, the overloaded circuitactivates a bimetallic strip which, with precision engineering, expands gracefully as heat builds up from excessive current. The meticulous design exploits the varying expansion rates of the composite metals, thereby inducing a controlled bending motionthat triggers a response.

Upon reaching a critical bending threshold,the system expertly engages the release rod, whichharnesses stored spring energyto smoothly separate the contactsand initiate a mechanical tripin a flawless sequence.

In the event of ashort circuit,a powerful magnetic force from the falling wheel emerges with precision, driven by the electromagnetic coil's dynamics,drawing the armature to engage, thus setting off a chain reaction with the release rodfor optimal safety control.
