BRM moulded case circuit breaker(MCCB)
BRM moulded case circuit breaker(MCCB) is one of the most advanced type breakers in the world, which adopts international advanced design and manufacture technology.They are suitable for short circuit and overload protection for circuit of AC 690V 50/60Hz, rated current from 12.5A to 630A. Its rated insulation voltage is 690V.It can make and break the non-frequently circuit in the nomal conditions. It takes protect effect when mouse cage motors non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage.It complies with IEC60947-2.
