Molded Case Circuit Breaker

YEM1(CM1) Moulded Case Circuit BreakersMolded 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).
MCCB comply anu
