Miniature Circuit Breakers & Supplementary Protectors

Uncompromising safety and comfort
Miniature circuit breakers (MCBs) ensure electrical safety in multiple applications. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.
