The Bussmann KLU-650 Limitron is a Class L time-delay bolt-on fuse rated for 650 A at 600 V AC, designed to protect industrial power circuits while tolerating brief startup surges. It uses a dual-element construction and a non-indicating bolt-on body that mounts securely to compatible fuse blocks, with an AC interrupt rating of 200 kA. The fuse body is fiberglass/melamine, and its dimensions measure about 2-1/2 in in diameter and 8-5/8 in in length. It is UL Listed under UL 248-10 (Guide JDDZ) and CSA Class 1422-02, and is manufactured in the USA as part of Eaton Bussmann’s Limitron line. The KLU-650 is compatible with Bussmann fuse blocks 51215 and 51235. This fuse is intended for general protection in power distribution where 600 VAC circuits may experience brief inrush or startup transients, providing reliable protection for high-current applications while remaining physically suited for bolt-on mounting in equipment racks and control panels.
