Bussmann KTN-R-70 - RK1 Class Fuse 70A (200kA AIC @250V)

Bussmann KTN-R-70 is a low-voltage current-limiting fuse from the LIMITRON family designed for circuit protection in industrial applications. It features a 70A current rating and 250V voltage rating with a high 200kA interrupting capacity at 250V for reliable short-circuit protection. The fuse construction utilizes a single-barrel RK1 class design with dimensions of 5.88 inches in length and 1.06 inches in diameter, weighing 1.3 lb. This current-limiting fuse meets industry standards for time-delay characteristics and provides coordinated protection in electrical distribution systems. Typical applications include motor branch circuits, feeder circuits, and industrial control panels where high-interrupting capacity and selective coordination are required.
