We are one of the best manufacturers of MCCB. Air circuit breaker from 630A to 6300A. 1600a 3200a 4000a
Product executive standard IEC60947-2
Molded Case Circuit Breakers MM1 series (hereinafter called as MM1 MCCB) is a newdesigned MCCB
developed and manufactured adopting international advanced technology. MM1 MCCB rated insulating
voltage AC 800V 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
