1. Application 

MM1E series intelligent moulded case circuit breakers is a new designed MCCB, developed and manufactured adopting international advanced
technology. MM1E MCCB rated insulating voltage AC 800V is suitable for using in the circuit of AC 50Hz, rated voltage 400V, rated working current up to
800A 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.
Circuit breaker can vertically installed, also can horizontal installed
Circuit breaker can not invert the coming line, just 1,3,5 connect the power line and 2,4,6 connect the loading line.
MM1E 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.
