The ABB S800 series of high-performance automatic differential circuit breakers has set a new standard of excellence, thanks to its high rated current, breaking capacity, selectivity and safety features. They are the ideal solution for protecting your systems.

Their compact design, excellent current limitation and circuit breaker position indicators are just some of the features that make this series particularly flexible and functional. In addition, customers can choose between cage or round terminals and select from a wide range of accessories.
