Detailed Product Description

Moulded Case Circuit Breakers YEM1(CM1) 

Molded Case Circuit Breakers YEM1 series (hereinafter called as Cm1 MCCB) is a new
designed MCCB developed and manufactured adopting international advanced technology.
CM1 MCCB rated insulating voltage AC 690V 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. CM1 MCCB with the advantages of the small volume, high breaking capacity, short over-arcing (some of specification is zero arcing), 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).
