Eaton Bussmann LPN-RK-250SP is a Low-Peak time-delay, Class RK1 fuse designed for branch circuit and feeder protection in industrial electrical systems. It features a 250A current rating and a 250V AC voltage rating, providing a high 300kA interrupting capacity at its rated voltage to safely clear severe short circuits. The fuse is constructed as a single-barrel device with a 2.36-inch diameter and an overall length of 8.63 inches, weighing 1.75 lb, and its current-limiting RK1 classification ensures efficient protection of downstream equipment by limiting let-through energy. It is engineered for reliable performance in demanding applications such as protecting motor circuits, transformers, and distribution panels where selective coordination and high fault current interruption are critical.
