| 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. |
