Bussmann LPS-RK-100 - Class RK1 Fuse 100A 600V (300kA AIC)

The Bussmann LPS-RK-100 is a Class RK1 low-voltage current-limiting fuse designed for circuit protection in industrial power distribution systems. It features a 100A current rating and 600V AC voltage rating with a 300kA interrupting capacity at 600V for reliable short-circuit protection. The fuse construction utilizes a single-barrel design with a 1.11-inch diameter and weighs 7 lb, incorporating time-delay characteristics to prevent nuisance tripping from motor starting currents. This fuse meets industry standards for RK1 classification, providing current limitation to protect electrical equipment from damage. Typical applications include motor branch circuits, feeder circuits, and industrial control panels where high fault current interruption is required.
