Product Description

Product Description

 

Working Principle: The inner workings of this state-of-the-art circuit breaker are a testament to its superior design and engineering.

When the current is overloaded, a critical process is triggered to ensure safety and prevent damage., the bimetallic strip expands gracefully due to the heating effect caused by the excessive current flow. The differential expansion coefficients between carefully selected metal layers result in a bending motion.

When this bending reaches a precise threshold, it triggers the release rod, which in turnunleashes stored spring energy, separating the contactsswiftly, and mechanically activating the trip mechanism; thus ensuring a swift response to electrical anomalies.

When the current is short-circuited, a remarkable and rapidreaction is set into motion. A magnetic force from the falling wheel is generated precisely at the base of the electromagnetic coil, compelling the armature to engage with the release rod. This sequence of actions effectively breaks the circuit, ensuring safety and preventing electrical mishaps.
