CNSX(NSX) Moulded Case Circuit Breaker (MCCB) is the one of the most advanced type Circuit Breakers in the world, which adopts international advanced design and manufacture technology. They are suitable for short circuit and overload protection for circuit of AC 690V 50/60Hz, rated current from 12. 5A to 1600A. It takes protecting effect when motors non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage. Fixed or withdrawable, front or rear connection, manual operating mechanism or motor mechanism is choice.
Electrical characteristics as per IEC60947-2 and EN60947-2
