Bussmann KTS-R-50 - RK1 Class Time-Delay Fuse 50A 600V (200kA AIC)

The Bussmann KTS-R-50 is a current-limiting, time-delay fuse from the LIMITRON family designed to provide reliable circuit protection in industrial electrical systems. It features a 50A current rating and 600V AC voltage rating with a high 200kA interrupting capacity at rated voltage. Constructed with a single-barrel design measuring 1.06 inches in diameter and 5-1/2 inches in length, this RK1 class fuse weighs 1 lb and incorporates current-limiting technology to protect against short-circuits and overload conditions. The fuse meets multiple certification standards including UL 248-12, CSA C22.2 No. 248.12, and CE markings for industrial compliance. Typical applications include motor branch circuits, transformers, and feeder circuits where time-delay characteristics and high interrupting ratings are required.
