Bussmannn LPS-RK-20SPI - RK1 Time-Delay Fuse 20A 600V (300kA AIC)

Bussmannn LPS-RK-20SPI is a low-voltage time-delay fuse designed for circuit protection in industrial electrical systems. It features a 600V AC/DC voltage rating and 20A current rating with a 300kA interrupting capacity at 600V, housed in a compact 1.06-inch diameter, 5-inch long RK1-class barrel construction. The fuse meets CE, UL (JFHR/JDDZ), and CSA (C22.2 No. 248.12) standards for reliable performance in motor control centers, switchgear, and panelboards. Its time-delay characteristics provide optimal protection against overloads while resisting nuisance tripping during temporary inrush currents.
