| DNS series moulded case circuit
breaker is one of the most advanced type breakers in the world,
which adopt international advanced design and manufacture fechnology.
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. |
