NOM1 series plastic outer covering type circuit breaker, Shell current can be customized. White cover MCCB Max current:800A
Application
Molded Case Circuit Breakers NOM1 series (hereinafter called as NOM1 MCCB) is a newdesigned MCCBdeveloped and manufactured adopting international advanced technology. MM1 MCCB rated insulatingvoltage AC 800V is suitable for using in the circuit of AC 50Hz /60Hz, rated voltage up to 690V, ratedworking current up to 630A to distribute electric power and to protect the line and the equipment from beingdamaged due to overload, short current and under-voltage. It can also be used for infrequently switch andstarting of motor and for motor overload, short circuit and under-voltage protections. MM1 MCCB with theadvantages of the small volume, high breaking capacity, short over-arcing (some of specification is zeroarcing), strong anti-vibration and so on.In accordance with the ultimate short circuit breaking capacity classified into four types: Type C (basic),Type L (standard), Type M (middle), Type H (high).
NOM1-63 has nine grades: (6), 10, 16, 20, 25, 32, 40, 50, 63ANOM-100 has ten grades: (10), 16, 20, 25, 32, 40, 50, 63, 80, 100ANOM1-160 has four grades: 100, 120, 140, 160ANOM1-225 has seven grades: 100, 125, 140, 160, 180, 200, 225ANOM1-400 has five grades: 225, 250, 315, 350, 400ANOM1-630 has three grades: 400, 500, 630ANOM1-800 has three grades: 630, 700, 800ANOM1-1250 has three grades: 800, 1000, 1250A
MCCB comply with the following standards:IEC 60947-1 and GB/T 14048.1 General IEC 60947-2 and GB/T 14048.2 Low voltage breakers.IEC 60947-4 and GB/T 14048.4 Contactors and motor starters.IEC 60947-5.1 and GB/T 14048.5 Electrical equipment of electromechanical control circuit.
