Littelfuse FLSR050 Time Delay Fuse Class Fuses - 50A 600VAC/300VDC RK5

The Littelfuse FLSR050 is a dual-element, time-delay Class RK5 fuse designed for reliable overcurrent protection in industrial and commercial electrical systems. Rated for 50 amperes, this fuse provides superior protection for circuits operating at 600 volts AC or 300 volts DC.

Key Features:

• Dual-element time-delay design allows temporary overloads while protecting against short circuits
• Class RK5 current-limiting construction reduces potential damage during fault conditions
• 600VAC/300VDC voltage rating for versatile application use
• 50 amp current rating for medium-duty circuit protection
• UL Listed and meets NEC requirements for branch circuit protection
• Interrupting rating of 200,000 amps RMS symmetrical

This time-delay fuse is ideal for motor circuits, transformer primaries, and other inductive loads where temporary inrush currents occur during normal operation. The dual-element construction provides excellent protection coordination and helps prevent nuisance tripping while delivering fast response to dangerous fault currents.
