It all started back in 1924 when the German inventor Hugo Stotz received the patent for the first resettable Miniature Circuit Breaker (MCB). This revolutionized the way we protect our electrical systems. 

Following Hugo Stotz’s spirit of innovation worldwide

The production of modern MCBs and protection devices still follows Hugo Stotz's spirit of innovation and is carried out not only in Heidelberg, Germany but all over the world. Since the invention of the first modern MCB, the technology continuously evolved across residential, commercial, and industrial settings, standardization and modularity, compact and user-friendly design, and product circularity intersect with energy efficiency requirements, regulatory and policy considerations and changing consumer behavior. Today, complete line protection, including MCBs, RCDs, AFDDs and SPDs, is providing increasingly higher performance, lower carbon footprint, and greater connectivity to make buildings around the world safe, smart, and sustainable.
