Frequently Asked Questions

What is the LITTELFUSE FLNR050 fuse used for?

The LITTELFUSE FLNR050 is a Class RK5 time-delay cylindrical fuse rated 50 A, 250 V AC, and 125 V DC. It protects motors, transformers, and lighting circuits from overcurrent and short circuits. Its time-delay characteristic allows harmless inrush currents without nuisance opening, making it ideal for industrial and commercial power distribution.

What are the specifications of the LITTELFUSE FLNR050 fuse?

The LITTELFUSE FLNR050 is a Class RK5, time-delay, non-indicating fuse from the FLNR series. It has a current rating of 50 A, voltage rating of 250 V AC and 125 V DC. The manufacturer part number is FLNR050. It is designed for cylindrical fuse holders and provides reliable overcurrent protection in branch circuits.

Where to buy LITTELFUSE FLNR050 fuses worldwide?

You can source the LITTELFUSE FLNR050 fuse through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time. 3G Electric supplies genuine LITTELFUSE components for industrial maintenance and OEM applications.

How to select the correct LITTELFUSE FLNR050 fuse for an application?

To select the LITTELFUSE FLNR050, verify the circuit voltage does not exceed 250 V AC or 125 V DC and the continuous load current is below 50 A. Ensure the fuse holder accepts Class RK5 cylindrical fuses. For motor circuits, confirm the time-delay characteristic handles starting inrush. Always consult the manufacturer's data sheet for coordination.
