Detailed Product Description

MCCB(circuit breaker, residual current circuit breaker)NF-CS series (hereinafter called as NF-CS MCCB) is a new designed MCCB developed and manufactured adopting international advanced technology. MM1 MCCB rated insulating voltage AC 600V is suitable for using in the circuit of AC 50Hz /60Hz, rated voltage up to 690V, rated working current up to 630A to distribute electric power and to protect the line and the equipment from being damaged due to overload, short current and under-voltage. It can also be used for infrequently switch and starting of motor and for motor overload, short circuit and under-voltage protections. MM1 MCCB with the advantages of the small volume, high breaking capacity, short over-arcing (some of specification is zero arcing), strong anti-vibration and so on.
