Abstract
When the short fault current is flowed into a fuse, the notch of element is melted, and burnbacked by arc plasma, which caused by the voltage of fuse at both ends. The cutoff ability of fuse is heavily influenced by the degree of burnback. In this paper, we investigated the amount of burnback to the applied voltage di/dt variation, As a result, we confirmed that the amount of burnback is proportional to the variation of the applied voltage.
