NS Case Moulded Circuit Breaker
NS series moulded case circuit breaker is one of the
most advanced type breakers in the world,which adopt international
advanced design and manufacture technolgy.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 rpotection overload,short
circuit and lacking voltage.
