The ABB S800 series high-performance automatic circuit breakers set a new standard of excellence, thanks to their high current rating, breaking capacity, selectivity and safety features. They are the ideal solution for protecting your systems. Compact design, excellent current limitation and circuit breaker position indicators are just some of the characteristics that make this series highly flexible and functional. In addition, customers can select between cage or ring terminals and can chose from a wide range of accessories. C-type characteristics guarantee a short circuit cut-off response of 3-10 with normal nominal current. Suited for use in circuits that normally produce surge currents, such as fluorescent lighting and female electrical connectors in commercial applications.
