Littelfuse FLNR-25 - RK5 Time Delay Fuse 25A (600V, 0.56" Diameter)

Littelfuse FLNR-25 is a low-voltage current-limiting fuse from the Powr-Gard family designed to provide reliable overcurrent protection in industrial electrical systems. It features a 25A current rating and a time-delay (TD) characteristic, allowing it to withstand temporary inrush currents while providing fast clearing of sustained overloads and short circuits. The fuse has a compact 1-barrel construction with a 0.56-inch diameter and meets RK5 class requirements for high interrupting capacity. This fuse complies with industry standards for branch circuit protection and is commonly used in motor control centers, industrial control panels, and power distribution equipment where coordinated protection is essential.
