Littelfuse FLNR005 UL Class RK5 Time Delay Fuse 5 Amp 250V

The Littelfuse FLNR005 is a UL Class RK5 dual-element time-delay fuse designed for reliable overcurrent protection in industrial and commercial electrical systems. This 5-amp fuse is rated for 250VAC/125VDC operation and provides superior short-circuit interrupting capacity.

Key Features:

• Dual-element construction provides time-delay characteristics to handle motor starting currents and temporary overloads
• UL Class RK5 rating ensures high interrupting capacity up to 200,000 amps at 250VAC
• Dimensionally compatible with Class H fuses for easy retrofitting without additional modifications
• 13/32" x 1-1/2" dimensions fit standard fuse blocks and holders
• Current-limiting design minimizes let-through energy during short circuits
• Rejection feature prevents installation of higher-rated fuses in the same holder

Class RK5 time-delay fuses are ideal for motor circuits, transformers, and other inductive loads where temporary inrush currents occur. The dual-element design withstands harmless overloads while providing fast clearing on sustained overloads and short circuits.
