Description
The Littelfuse FLNR050 is a 50 amp, 250 V time-delay Class RK5 fuse engineered to provide dependable overcurrent protection in commercial and industrial electrical systems. Its dual-element, slow-blow design allows temporary inrush currents—commonly generated by motors, transformers, and other inductive loads—to pass without nuisance fuse openings, while still delivering strong protection against sustained overloads and short circuits. With high interrupting capacity and consistent response performance, the FLNR050 helps safeguard sensitive equipment and improve overall system reliability. Its durable cartridge construction makes it ideal for use in power distribution panels, motor control centers, and industrial machinery applications.
