NS Series Molded Case Circuit Breakers The company adopts international advanced technology developed by the new circuit breakers. Its design reflects the highest level of the limiting principle and manufacturing technology, there is a knot Schneider disconnect NS-100N NS-250N structure perfect, all modular, high breaking characteristics. AC 690V, frequency 50-60Hz, the use of the 12.5 ~ 630A rated current power lines with short circuit and overload protection. Rated insulation voltage of 690V, normal under conditions of frequent closed or disconnected use, also can be used for squirrel cage motors non-frequent start, operation interruption, overload, and to protect motors, short circuit and under voltage with. NS-100N, NS-160N, NS-250N, NS-400N, NS-630N, NS-800N, NS-1000N, NS-1250N, NS-1600N
