MCBs (miniature circuit breakers) work as part of the distribution system of an electrical installation; their specific role is to cut current if an overload or short circuit is detected. ABB electrical products provide products and services from substation to socket; their circuit breakers are known to be one of the best solutions available for both breaking the current when there is an issue and restoring it once the fault is remedied. The miniature circuit breakers of the System pro M compact® series S 200 and S 200 M provide state-of-the-art safety and comfort. They stand out due to their high performance and the wide range of accessories and approvals.
