NS Series Mould Case Circuit Breakers

Product Description

NS Series Mould Case Circuit Breakers NS series moulded case circuit breaker is one of the most advanced type breakers in the world, which adopt international advanced design and manufacture technology. They are suitable for short circuit and overload protection for circuit of AC **0V *0/*0Hz, rated current from *2.5A to **0A. It takes protect effect when mouse cage motors non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage.
