Bussmann LPN-RK-150 - Class RK1 Time-Delay Fuse 150A 250V (300kA AIC Rating)

The Bussmann LPN-RK-150 is a Class RK1 low-voltage time-delay fuse engineered to provide reliable branch circuit and feeder protection against overcurrents and short circuits in industrial electrical systems. It features a 150A current rating and a 250V AC voltage rating, with an impressive 300,000A interrupting rating at 250V AC to safely handle high fault currents. Constructed as a single-barrel fuse with knife blade terminals, it measures 1.61 inches in diameter and weighs 5.19 lb, featuring a current-limiting design that reduces let-through energy during fault conditions. This fuse meets industry standards for RK1 classification and is UL listed for safety compliance. Typical applications include motor branch circuit protection, transformer protection, and industrial control panel applications where time-delay characteristics prevent nuisance tripping during temporary overloads.
