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. | |||||
