Frequently Asked Questions

What is a Littelfuse FLSR090 fuse used for?

The Littelfuse FLSR090 is a Class RK5 time-delay fuse rated 90 A, 600 V AC / 300 V DC. It protects motor circuits, transformers, and other inductive loads from short circuits and sustained overloads, while allowing harmless inrush currents to pass without nuisance opening.

What are the specifications of the Littelfuse FLSR090 fuse?

The Littelfuse FLSR090 is a Class RK5, time-delay, non-indicating fuse rated 90 A, 600 V AC and 300 V DC. It belongs to the FLSR series and is designed for branch-circuit protection of motor loads and equipment with high inrush currents.

Where to buy Littelfuse FLSR090 fuses worldwide?

3G Electric supplies the Littelfuse FLSR090 fuse to customers worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time on this Class RK5 time-delay fuse.

How to select the right Littelfuse FLSR series fuse for a motor circuit?

To select the correct Littelfuse FLSR series fuse, match the voltage rating (600 V AC / 300 V DC) and current rating (90 A for the FLSR090) to your circuit. The time-delay characteristic accommodates motor starting inrush. Always verify the interrupting rating meets system fault current requirements.
