Bussmann KTS-R-400 - RK1 Time-Delay Fuse 400A (200kA AIC @600V)

The Bussmann KTS-R-400 is a current-limiting, time-delay fuse from the LIMITRON family designed to provide reliable overcurrent protection for industrial power circuits. It features a 600V AC voltage rating and a 400A current rating, engineered to safely interrupt high fault currents. The fuse is constructed as a single-barrel RK1 class device with compact physical dimensions of 11.63 inches in length and 2 inches in diameter, weighing 5 lb for robust industrial use. This fuse meets industry standards for current-limiting protection and carries a 200,000A interrupting rating at 600V AC. Typical applications include motor branch circuits, feeder circuits, and industrial control panels where time-delay characteristics and high interrupting capacity are required.
