Littelfuse FLSR075 is a UL Class RK5 dual-element time-delay fuse designed for reliable circuit protection in industrial power distribution systems. It features a 600V AC voltage rating and 75A current rating with 200kA interrupting capacity at 600V for high-fault current protection. The fuse construction includes a 1.31-inch diameter body with 7-7/8-inch length and single-barrel design weighing 5.19 lb. It complies with UL 248-12 Class RK5 standards and carries CE, CSA, and QPL-W-F-1814 certifications for industrial safety requirements. Typical applications include motor branch circuit protection, transformer protection, and industrial control panel applications where time-delay characteristics prevent nuisance tripping during motor starting currents.
