Littelfuse FLNR-225ID - Low Voltage Time-Delay Fuse 225A (RK5 Class, 250V/600V)

Littelfuse FLNR-225ID is a low-voltage time-delay fuse designed for circuit protection in industrial electrical systems. It features a 250V AC/600V DC voltage rating with a 225A current capacity, housed in a compact 0.56-inch diameter cylindrical body with a single-barrel RK5 class construction. The fuse meets UL/CSA standards and employs a time-delay (TD) characteristic for reliable overload protection while withstanding temporary inrush currents. Typical applications include motor branch circuits, transformers, and power distribution panels where coordinated protection is required.
