High breaking capacity NS silver ornamental electrical Molded case circuit breaker

KNS MOULDED CASE CIRCUIT BREAKER
APPLICATIONS
KNS moulded case circuit breaker is one of the most advanced type breakers in the world,
which adopts 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.
