Bussmann NON250 One Time Fuse 250A 250V High Current

BUSSMANN NON-250 is a one-time, non-current-limiting fuse designed for general protection in 250 V AC circuits, rated for 250 A with a 10 kA interrupt rating at 250 VAC to quickly clear fault currents in equipment. This high-current, non-resettable fuse belongs to Eaton’s Bussmann NON series (Class K5/H) and is specified as a general‑purpose, non‑current‑limiting device intended for single-use protection. The fuse features a cartridge blade body with a melamine housing, and typical physical dimensions are about 8-5/8 inches in length and roughly 2-3/8 inches in diameter, accommodating blade-end terminations. Compliance notes include CSA 1421-01 in some markets, and distributors consistently catalog it as NON-250 under the Bussmann/Eaton line.
