Molded Case CircuitBreakers MM1 series (hereinafter called as MM1 MCCB) is anewdesigned MCCB
developed and manufactured adopting international advancedtechnology. 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 toprotect the line and the equipment from being
damaged due to overload, short current and under-voltage. It canalso be used for infrequently switch and
starting of motor and for motor overload, short circuit andunder-voltage protections. MM1 MCCB with the
advantages of the small volume, high breaking capacity, shortover-arcing (some of specification is zero
arcing), strong anti-vibration and so on.
In accordance with the ultimate short circuit breaking capacityclassified into four types: Type C (basic),
Type L (standard), Type M (middle), Type H (high).
