Bussmann by Eaton KTN-R 300 Limitron fuse is a fast-acting, current-limiting RK1 cartridge fuse rated for 300 A at 250 V (AC/DC) and designed to interrupt faults quickly. It uses a rejection-style cartridge body with a 13/32 in diameter and a length that varies with the amp rating. The device provides an interrupting rating of 200 kA at 250 VAC and 100 kA at 250 VDC, making it suitable for high-current, 250 V systems in low-voltage protections. This Limitron fuse is intended for protection in control panels, power-distribution gear, and industrial equipment where rapid fault clearing is essential.
