Littelfuse LLSRK-3ID - RK1 Time-Delay Fuse 3A 600V (300kA AIC)

Littelfuse LLSRK-3ID is a time-delay, current-limiting fuse from the Powr-Gard family designed to provide superior short-circuit and overload protection in low voltage industrial power distribution systems. It features a 600V AC voltage rating with a 3A current rating, capable of interrupting up to 300kA at 600V AC. The fuse is constructed as a single-barrel unit with a 0.81-inch diameter and ferrule connections, weighing 5 lb, and is built with a sand-filled design for current limitation and time-delay characteristics. This RK1 class fuse complies with industry standards for high-performance circuit protection. It is typically applied in motor branch circuits, transformers, and other equipment where withstanding temporary inrush currents is critical.
