Littelfuse FLNR003 Time Delay Fuse 3 Amp 250V Class RK5

The Littelfuse FLNR003 is a 3 amp, 250 volt time delay fuse designed for reliable overcurrent protection in electrical circuits. This Class RK5 fuse features dual-element, time-delay construction that provides excellent protection against both short circuits and overloads while allowing temporary surge currents during motor starting and transformer inrush.

Key Features:

• 3 amp current rating at 250 volts AC
• Class RK5 time delay fuse with 600,000 AIC interrupting rating
• Dual-element design withstands temporary overloads and inrush currents
• 13/32" x 1-1/2" dimension (standard ferrule contact design)
• UL Listed and CSA certified for safety compliance
• Rejection feature prevents replacement with lower interrupting capacity fuses

The FLNR series fuses are ideal for motor circuits, transformer primary protection, and other applications requiring time-delay characteristics. The rejection-style design ensures that only Class RK5 or higher rated fuses can be installed, maintaining proper circuit protection levels.
