Miniature Circuit Breakers – MCBs

Small in size, high in performance

A hundred years ago, Hugo Stotz revolutionized the world of electrical installation by inventing the first-ever resettable Miniature Circuit Breaker (MCB). Since then, MCBs have become a vital component of modern electrical systems, providing peace of mind to users and safeguarding them and their belongings.

Today, as we tackle the challenges of energy transition, sustainability targets and labor shortages, MCBs are evolving with enhanced performance, more flexibility in installation, greater connectivity and a smaller size. These changes are aimed at meeting the changing needs of modern electrical systems and ensuring protection and safety for all.
