Product Description

NS series CE MCCB
NS series moulded case circuit breaker/mccb is one of the most advanced type breakers in the world, which adopt international advanced design and manufacture fechnology. They are suitable for short circuit and overload protection for circuit of AC 690V 50/60Hz, rated current from 12.5A to 630A. It takes protect effect when mouse cage motors non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage.
