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 produced by motors, transformers, and inductive loads—to pass without nuisance fuse openings, while still delivering reliable protection against sustained overloads and short circuits. Built with a cartridge-style construction and high interrupting capacity, the FLNR050 enhances equipment protection and system safety in demanding environments such as motor control centers, distribution panels, and industrial machinery.
Key Features:
- 50 amp current rating for heavy-duty circuit protection
- 250 V voltage rating for commercial and industrial systems
- Time delay (slow blow) dual-element design handles inrush currents
- Class RK5 fuse for strong current-limiting performance
- High interrupting capacity for enhanced safety
- Cartridge-style construction for secure installation
- Ideal for motors, transformers, and power distribution applications
