Littelfuse FLNR600 Time Delay Fuse 600 Amp 250V Class RK5

The Littelfuse FLNR600 is a 600-amp, 250-volt time delay fuse designed for reliable overcurrent protection in industrial and commercial electrical systems. This Class RK5 dual-element fuse provides superior protection for motor circuits, transformers, and other inductive loads where temporary inrush currents are common.

Key Features:

• 600 amp current rating at 250 volts AC
• Class RK5 time delay (dual-element) design for superior short-circuit and overload protection
• High interrupting rating of 200,000 amperes RMS symmetrical
• Designed to provide time delay on overloads and fast response to short circuits
• UL Listed and CSA certified for safety and reliability
• Ideal for motor circuits, welders, and high-inrush applications

The FLNR series features dual-element construction that allows temporary overloads and inrush currents without nuisance blowing, while providing fast fault protection when needed. This rejection-style fuse ensures proper fuse class installation and prevents the use of incorrect fuse types in RK5 fuseholders.
