Littelfuse FLNR-350ID - Low Voltage Fuse 350A RK5 Time-Delay (600V AC)

Littelfuse FLNR-350ID is a low voltage current-limiting fuse designed for providing superior short-circuit and overload protection in industrial power distribution systems. This 350A rated fuse operates with a 600V AC voltage rating and features a time-delay (TD) characteristic that allows for temporary overloads without nuisance opening while maintaining rapid response to fault conditions. Constructed as a single-barrel RK5 class fuse with a 0.56-inch diameter, the unit features a durable ceramic body and silver-plated ferrules for reliable connectivity. The fuse complies with UL 248-12 standards and is CSA certified for industrial applications. Typical applications include motor branch circuit protection, feeder circuit protection, and service entrance equipment in commercial and industrial facilities.
