Littelfuse FLSR012 - RK5 Time-Delay Fuse 12A 600V (200kA AIC)

Littelfuse FLSR012 is a UL Class RK5 dual-element time-delay fuse designed for overcurrent protection in industrial electrical systems. It features a 600V AC/DC voltage rating and 12A current rating with a 200kA interrupting capacity at 600V for robust short-circuit protection. The fuse measures 5 inches in length with a 0.81-inch diameter barrel construction, meeting UL 248-12 Class RK5, CSA, and QPL-W-F-1814 standards for safety and reliability. Certified for CE compliance, this fuse is commonly used in motor branch circuits, transformers, and power distribution panels where time-delay characteristics prevent nuisance tripping during temporary inrush currents.
