A fuse assembly having an end cap that includes a recessed retention body. The recessed retention body can include first and second retention walls and an engagement surface. The first and second retention walls can extend at least in a generally outwardly direction from the retention surface to an outer surface of the end cap, and extend between first and second ends of the first end cap in a direction that is generally parallel to a central longitudinal axis of the fuse assembly. The engagement surface can have one or more walls that downwardly and outwardly extend in divergent directions from an apex of the engagement surface and toward a corresponding one of the first or second retention walls. The apex can be positioned at a central location between the first and second retention walls, and extends in a direction that is generally parallel to the central longitudinal axis.

The present invention relates to a high breaking capacity strip fuse, comprising an insulating housing and a fusing element. The fusing element includes a fusible part, a first connecting terminal and a second connecting terminal which are arranged at two ends of the fusible part and are integrally connected with the fusible part; the fusible part is fixed in the sealed cavity of the housing, and the sealed cavity is filled with insulating material. The present invention provides a fuse filling with insulating material, such as Silicone, quartz sand, resin, ceramic powder/ceramic sand, steatite powder/steatite sand, or saponite powder/saponite granules, in the sealed cavity, to solve the problem of causing the air to ionize and triggering arcing phenomenon of existing fuse during overload.
