Miniature Circuit Breakers (MCBs) ensure electrical safety in homes, offices and other buildings as well as for industrial applications by protecting electrical installations against overloads and short-circuits. Once a fault is detected, the MCB automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.

For 100 years, we have continued to innovate MCBs and expand our product line to meet the demands of various applications and markets. Our products are compliant with global product standards such as IEC, UL and CSA. This established and certified portfolio is designed to provide maximum safety for buildings, assets and infrastructure.
