WebThe rated voltage (U N) of a fuse link has to be at least equal or higher than the operating voltage of the device or assembly unit which is to be protected with the fuse link. If the operating voltage is very low, the fuse link's natural resistance (voltage drop) must possibly be taken into consideration. The voltage drop (U N) is measured ...
