Frequently Asked Questions

What is the LITTELFUSE FLNR045 fuse used for?

The LITTELFUSE FLNR045 is a Class RK5 time-delay fuse rated 45 A, 250 V AC / 125 V DC. It protects motors, transformers, and other inductive loads from short circuits and sustained overloads. Its non-indicating design suits industrial control panels and distribution equipment where visual blown-fuse indication is not required.

What are the specifications of the LITTELFUSE FLNR045?

The FLNR045 is a Class RK5, time-delay, non-indicating fuse from the FLNR Series. It carries 45 A continuous current at 250 V AC or 125 V DC. The manufacturer part number is FLNR045. Time-delay characteristics allow it to withstand temporary inrush currents common in motor-starting applications.

Where to buy LITTELFUSE FLNR045 worldwide?

3G Electric supplies the LITTELFUSE FLNR045 fuse worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time. We source genuine LITTELFUSE components for industrial maintenance and OEM requirements.

How to select the correct LITTELFUSE FLNR045 fuse?

Select the FLNR045 when your circuit requires a 45 A, 250 V AC or 125 V DC Class RK5 time-delay fuse. Verify that the available fault current does not exceed the interrupting rating of the RK5 class. Always match the fuse holder or disconnect switch to the same Class RK5 rejection-style mounting for proper fit and safety.
