Littelfuse FLNR001 Class Time Delay Fuse - 1A 250V RK5

The Littelfuse FLNR001 is a Class RK5 time delay fuse designed to provide reliable overcurrent protection in electrical circuits. This dual-rated fuse is rated for 1 amp at 250 volts AC or 125 volts DC, making it suitable for a wide range of industrial, commercial, and OEM applications.

Key Features:

• 1 amp current rating with 250VAC/125VDC dual voltage capability
• Class RK5 time delay design allows temporary overloads while protecting against short circuits
• Rejection-type construction prevents replacement with lower interrupting capacity fuses
• 200,000 amp interrupting rating (AC) provides high short-circuit protection
• Standard 13/32" x 1-1/2" dimensions fit Class R fuse clips and holders
• UL Listed and CSA Certified for safety compliance

The time delay characteristic makes this fuse ideal for motor circuits, transformers, and other inductive loads where inrush currents occur during startup. The FLNR series features a current-limiting design that helps protect downstream components from damaging fault currents.
