Littelfuse FLNR15 - Class RK5 Fuse 15A 600V (200kA Interrupt Rating)

Littelfuse FLNR15 is a low-voltage current-limiting fuse designed for circuit protection in industrial electrical systems. It features a 600V AC rating with a 15A current capacity, housed in a durable ceramic body with tin-plated copper end caps for reliable conductivity. The fuse meets UL/CSA standards for time-delay operation, providing overload protection while withstanding temporary inrush currents. Its compact 10.3mm x 38mm cylindrical design suits panelboards and disconnect switches. Typical applications include motor control centers, transformers, and power distribution equipment requiring Class RK5 protection.
