A gauge for determining the operational viability of a device that requires that a consumable or otherwise erodible material for safe and/or efficient operation reside along or near an inside wall of a cavity, for example, a fuse tube containing an ablative arc-extinguishing material as found in a fused cutout, is provided, which gauge measures whether a sufficient quantity of the material to be consumed remains.

A pressure-compensated fuse assembly may include a first chamber housing a first fluid and a plurality of solid particles. Additionally, the fuse assembly may include a second chamber housing a second fluid. Further, the fuse assembly may include a pressure compensator disposed between the first chamber and the second chamber. The pressure compensator may be configured to transfer pressure from the second fluid in the second chamber to the plurality of solid particles in the first chamber.

A fuse includes a body, a first conductive terminal coupled with a first end of the body, and a second conductive terminal coupled with a second end of the body. The body, the first conductive terminal, and the second conductive terminal define an exterior of the fuse. The fuse also includes an interruption assembly including a fusible element. The fusible element includes carbon fiber, is disposed on a conductive path between the first conductive terminal and the second conductive terminal, and is configured to break when a current through the fusible element exceeds a predetermined current.
