Abstract
An electric fuse having a tubular casing, an arc-quenching filler, a pair of terminal plugs closing the ends of the casing and fusible elements conductively interconnecting said pair of terminal plugs. The thermal duty imposed upon said arc-quenching filler is equalized so that equal amounts of filler are caused to absorb approximately equal amounts of heat. This is achieved by immobilizing the positions of the fusible elements and by giving them such a shape that heat dissipation is substantially equalized. In other words, the position of the fusible elements relative to the casing must be in such a way that they are not displaced when the fuse is filled with pulverulent arc-quenching filler, and the arc path of one of the fusible elements must be separated as much as possible from the arc path of the other fusible element.
