Product Description

Product Description

 

Working Principle:

The sophisticated mechanism of the Mingtuo Moulded Case Circuit Breaker MCCB by Zhejiang Mingtuo Electric Technology Co., Ltd. ensures safety by effectively managing overloadedcurrents. When the bimetallic strip is exposed to excessive current, it heats up, causing it to expand. The unique expansion coefficients of the distinct metal layers cause a bending motion, providing a crucial role in circuit protection.

The bending action progressively reaches a predetermined thresholdwhere it activates the release rod, which in turnreleases stored spring energy, effectively disconnecting the contacts, and mechanically triggeringa trip; thus,

in the event of ashort circuit,an impressive falling wheel magnetic force is instantly generated at the base of the electromagnetic coil.This force swiftly draws the armature to initiate a decisive collision with the release rod,ensuring the utmost protection and reliability for each electrical circuit.
