Bussmann KTN-R-100 - RK1 Time-Delay Fuse 100A (200kA AIC @250V)

Bussmann KTN-R-100 is a Class RK1 low-voltage current-limiting fuse designed for circuit protection in industrial electrical systems. It features a 250V AC voltage rating and 100A current rating with a 200kA interrupting capacity at rated voltage, housed in a compact cylindrical body measuring 1.2" (30.5mm) in diameter and 5.85" (148.6mm) in length. The fuse's time-delay characteristic and RK1 classification ensure reliable protection against overloads and short circuits while meeting industry standards for electrical safety. Typical applications include motor control centers, panelboards, and switchgear requiring high-interrupting capacity protection.
