Cooper Bussmann LPS-RK-20 - Low-Peak Time-Delay Fuse 20A (300kA AIC, 600V)

Cooper Bussmann LPS-RK-20 is a Low-Peak time-delay fuse designed for providing superior circuit protection in low voltage electrical systems. This 20A rated fuse operates at 600V AC with a high interrupting rating of 300kA, featuring a single-barrel RK1 class construction with a 0.81-inch diameter for reliable performance. Engineered to meet industry standards for time-delay characteristics, it prevents nuisance tripping from motor starting currents and other temporary overloads. The fuse is commonly applied in industrial control circuits, motor branch circuits, and transformer protection where durable, time-delay protection is essential.
