In the event of overload or a short-circuit, miniature circuit breakers (MCBs) safely cut the connected circuit and thus reliably protect electrical systems and devices against damage. MCBs in the BTB Electric portfolio are also easy to assemble and install. The devices feature a uniform design, and can be expanded to include many more functions thanks to an extensive range of accessories. For industries, buildings or infrastructure – our extensive portfolio has the right MCB for every application
