The Omega 25.1500.54 (ST522320) is a 5x20mm glass cartridge fuse rated for 20A at 250V, supplied in a 5-piece pack. It uses a slow-blow (delayed) characteristic to tolerate brief inrush currents without nuisance tripping.

The fuse body is glass for clear visual inspection of the element, and the end caps are nickel-plated brass to maintain low contact resistance in standard fuse holders.
