Littelfuse FLSR-100 - RK5 Class Time-Delay Fuse 100A 600V (200kA AIC)

Littelfuse FLSR-100 is a low voltage fuse designed for providing high-interrupting capacity circuit protection in industrial power distribution systems. This 100A rated fuse operates at 600V AC/DC and features a 200kA interrupting rating to safely clear high-level fault currents. Constructed as a single-barrel, plug-in type fuse with a 1.31-inch diameter, it utilizes RK5 class time-delay characteristics to prevent nuisance tripping from motor starting currents. The fuse meets industry standards for reliable performance in demanding environments and is commonly applied in panelboards, switchboards, and industrial control equipment where robust circuit protection is required.
