Frequently Asked Questions

What is the LITTELFUSE FLNR030 fuse used for?

The LITTELFUSE FLNR030 is a Class RK5 time-delay fuse rated 30 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 FLNR030?

The LITTELFUSE FLNR030 is a Class RK5, FLNR Series, time-delay, non-indicating cylindrical fuse. It is rated 30 A at 250 V AC and 125 V DC. The manufacturer part number is FLNR030. It provides branch-circuit protection for motor circuits and other equipment requiring time-delay characteristics to handle inrush currents.

Where to buy LITTELFUSE FLNR030 worldwide?

Contact us for availability and lead time. We source and deliver genuine LITTELFUSE components to support maintenance and production needs anywhere.

How to select the correct LITTELFUSE FLNR series fuse for an application?

Select the FLNR series fuse based on continuous load current (typically 125% of motor full-load amps), available fault current (Class RK5 interrupting rating), and voltage (250 V AC or 125 V DC). The time-delay feature handles motor start-up surges. Always verify the fuse holder or disconnect switch is rated for Class RK5 fuses.
