Littelfuse FLSR040 is a UL Class RK5 dual-element time-delay fuse designed for reliable circuit protection in industrial applications. It features a 600V AC voltage rating and 40A current rating with 200kA interrupting capacity at 600V for high-fault current protection. The fuse construction includes a single-barrel design measuring 1.06 inches in diameter with a 5-1/2 inch length and weighs 5.19 lb, built for durable performance. It complies with UL 248-12 Class RK5 standards and carries CE, CSA, and QPL-W-F-1814 certifications for quality assurance. Typical applications include motor branch circuit protection, transformer protection, and industrial control panel circuits where time-delay characteristics prevent nuisance tripping during temporary overload conditions.
