Bussmann LPN-RK-15SP - Class RK1 Time-Delay Fuse 15A 250V (300kA AIC Rating)

The Bussmann LPN-RK-15SP is a Class RK1 low-voltage time-delay fuse designed to provide reliable circuit protection for motor circuits and transformers while withstanding temporary overloads. It features a 15A current rating and 250V AC voltage rating with a high 300kA interrupting capacity at rated voltage. The fuse construction utilizes a single-barrel design with a 0.56-inch diameter and 2-inch length, manufactured with current-limiting technology to provide low peak let-through current and energy limitation. This fuse meets UL, CSA, and CE standards including UL File E4273 and CSA File 53787 for safety compliance. Typical applications include industrial control panels, motor branch circuits, and transformer protection where time-delay characteristics and high interrupting ratings are required.
