Product Description
NS circuit breaker is one of the most advance type breaker in the world, which adopts international advanced design and manufacture technology. They are suitable for thort circuit and overload protection for circuit of AC 690V 50/60Hz, rated current from 12.5A to 630A. It takes protact effect when mouse cage motors non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage.
