The Omega 25.1500.52 (ST522316) is a 5x20mm delayed-action glass fuse rated 15A at 250V, designed for general electronic and appliance circuit protection. Its delayed characteristic tolerates short inrush currents without nuisance tripping while still protecting against sustained faults.

The cylindrical glass body holds nickel-plated brass end caps that resist corrosion and maintain reliable contact in standard 5x20mm fuse holders. Supplied in a pack of 4 for spares and multi-circuit use.
