Product Description

The LITTELFUSE FLNR090 is a Class RK5, time-delay blade fuse from the FLNR Series, rated at 90 A with 250 V AC and 125 V DC capacity. This non-indicating fuse is designed for overcurrent protection in industrial electrical systems.

Frequently Asked Questions

What is the LITTELFUSE FLNR090 fuse used for?

The LITTELFUSE FLNR090 is a Class RK5 time-delay fuse rated 90 A, 250 V AC, and 125 V DC. It protects industrial motor circuits, transformers, and lighting panels from overloads and short circuits. Its time-delay characteristic handles inrush currents without nuisance opening, making it suitable for heavy-duty equipment in manufacturing and process plants.

What are the specifications of the LITTELFUSE FLNR090 fuse?

The LITTELFUSE FLNR090 is a Class RK5, time-delay, non-indicating fuse. It carries 90 A at 250 V AC and 125 V DC. The series is FLNR, and the manufacturer part number is FLNR090. It is designed for branch-circuit protection where high inrush currents occur, such as motor starters and control transformers.

Where to buy the LITTELFUSE FLNR090 fuse worldwide?

Contact us for availability and lead time. We source and deliver this Class RK5 time-delay fuse to support your maintenance and project needs anywhere.

How to select the correct LITTELFUSE FLNR090 fuse for a motor circuit?

To select the LITTELFUSE FLNR090, match the fuse amp rating (90 A) to the motor full-load current plus starting inrush. Verify voltage rating (250 V AC or 125 V DC) exceeds system voltage. Use the time-delay characteristic to avoid nuisance trips during startup. Consult the motor nameplate and NEC/CEC guidelines for proper sizing.
