Littelfuse FLSR-015ID is a low-voltage current-limiting fuse designed for branch circuit protection in industrial power distribution systems. It features a 600V AC rating and a 15A current rating to safeguard against overcurrents and short circuits. The fuse is constructed with a single-barrel, ferrule-connected design, has a diameter of 0.81 inches, and carries an RK5 class rating for time-delay performance. It complies with industry standards for high interrupting capacity, rated for 200kA at 600V. Typical applications include the protection of motor circuits, transformers, and other electrical equipment where reliable, time-delay overcurrent protection is required.
