Littelfuse FLNR20 - RK5 Time-Delay Fuse 20A@250V (200kA AIC)

Littelfuse FLNR20 is a time-delay low-voltage fuse designed for circuit protection in industrial power distribution systems. Rated for 250V AC/DC operation with a 20A current capacity, it features a ferrule rejection connection and RK5 class rating for high-performance fault interruption. The compact 0.56" diameter fuse body provides 200kA interrupting capacity at rated voltage while maintaining UL/CSA compliance. Its time-delay characteristic protects against inrush currents while responding quickly to short circuits, making it ideal for motor branch circuits, transformers, and power distribution panels.
