Littelfuse FLSR175ID is a UL Class RK5 dual-element time-delay fuse designed for circuit protection in industrial electrical systems. It features a 600V AC rating and 175A current capacity with a 200kA interrupting rating at 600V for high-fault protection. The fuse measures 1.84" in diameter with a 9-5/8" length and 1 lb weight, constructed with visible indication for blown fuse detection. It meets CSA, cUL, and UL standards for safety compliance in North American applications. Typical uses include motor branch circuits, transformers, and feeder protection where time-delay characteristics prevent nuisance tripping during inrush currents.
