Bussmann KTK-R-15 is a low-voltage current-limiting fuse designed for branch circuit protection in industrial control panels and motor circuits. It features a 15A current rating and a 600V AC voltage rating, with a compact 1-1/2 inch body length and 0.41-inch diameter for space-efficient installation. Constructed as a single-barrel, fast-acting fuse, it provides a 200kA interrupting rating at 600V to safely clear high fault currents and is certified to UL 248-4 and CSA Class 1422-02 standards. This Class CC fuse is typically applied in the protection of control transformers, solenoids, and small motor loads.
