63A100A225A400A630A800A 3P/4P To supply circuit breaker NS/NSX mould case circuit breaker

Product Overview

Description

           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 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.
