Abstract
A fuse housing for safe outgassing of a fuse is disclosed. The fuse housing features labyrinth walls disposed at opposing sides of the fuse housing. The labyrinth walls feature serpentine paths for the flow of outgassing material. At an end of the serpentine paths which is farthest away from a fuse element are vent channels. The vent channels are narrower in depth than that of the serpentine paths of the labyrinth walls, facilitating a suctioning effect during outgassing. Conductive material deposits along the serpentine paths so that the fuse maintains a high OSR rating. By directing and controlling the outflow of gases, the fuse housing is able to reduce the temperature of the gases produced. The fuse housing is also able to reduce the physical and observable effects of outgassing.
