Abstract: A fuse cutout assembly (21) including a containment housing (22), a fuse (23), amounting assembly (24) mounting the fuse (23) in the housing (22) for electrical connection to an electrical circuit. A plunger assembly (29) is movably mounted at least partially inside the housing (22) and preferably surrounding the fuse (23). An electrical conductor (28) is electrically connected to the fuse (23) and mechanically connected to the plunger assembly (29). The plunger assembly (29) is supported in the housing (22) in a first position and is formed to be propelled inside the housing (22) away from the first position to a second position by the hot gases generated upon rapid melting of the fuse (23). Movement of the plunger assembly (29) is preferably yieldably resisted by the air trapped between the plunger assembly (29) and the housing (22), which may be vented during plunger movement. Additional venting (94) for excessive pressure buildup can be provided in the housing (22), and a method of containing the hot gases and metals generated during fuse melting and retaining the components of the cutout assembly (21) is also provided.
