Circuit Breaker>>Mould Case Circuit Breaker>>NF Series
1.Description
NF series moulded case circuit breaker(below for short MCCB,ELCB) is applicable circuit of AC 50Hz(or 60Hz), rated insulation voltage 690V, rated operating voltage up to 660V(690V), rated operating voltage up to 250V(DC). The rated operating current 3A-800A, for distribute energy of electricity and infrequent making and breaking circuit, and infrequent starting of motor(rated operating current up to 400A).At normal condition, they are provided with the function of the protection against overload adn short-circuit and undervoltage.Our MCCB comply with standard of IEC947-2,GB14048.2 and so on.
