Bussmann LPN-RK-150SP - Low-Peak Time-Delay Fuse 150A (300kA AIC, Class RK1)

The Bussmann LPN-RK-150SP is a Low-Peak time-delay, current-limiting fuse from Eaton's LPN-RK family, designed to provide superior short-circuit and overload protection for industrial electrical systems. It features a 150A current rating and a 250V AC voltage rating, with an impressive 300kA interrupting rating at 250V AC to safely handle high fault currents. The fuse is constructed as a single-barrel, Class RK1 device with a 1.61-inch diameter and a 7-1/8 inch length, weighing 1 lb, and is manufactured in Mexico. It complies with major safety standards including UL and CSA certifications (UL File E4273, Guide JFHR/JDDZ; CSA File 53787, Class 1422-02, C22.2 No. 248.12), and carries the CE mark. This fuse is typically applied in motor branch circuits, feeder circuits, and transformer protection where its time-delay characteristic prevents nuisance openings from motor starting currents.
