Circuit - breakers
Low voltage moulded-case circuit-breakers series KN are remarkably compact and have a high breaking capacity. Owning to their design characteristics they ensure great reliability and require minimum mainteance, for rated currents from 20 up to 1600A.
Air Circuit-Breakers series KA for rated current from 200 up to 6300A are remarkably compact and have a high breaking capacity. Owning to their design characteristics (the world's first ACB with two breaking contacts per phase) they ensure great reliability.
Circuit-Breakers with residual current protection are the special version of circuit-breakers type KN they combine function of circuit-breaker and device with residual current protection, for rated currents from 20 up to 250A.
