Frequently Asked Questions

What is a Littelfuse FLSR02.5 fuse used for?

The Littelfuse FLSR02.5 is a Class RK5 time-delay cylindrical fuse rated 2.5 A, 600 V AC / 300 V DC. It protects motor circuits, transformers, and other inductive loads from overcurrent while tolerating harmless inrush surges. Common in industrial control panels and power distribution.

What are the specifications of the Littelfuse FLSR02.5 fuse?

The Littelfuse FLSR02.5 is a Class RK5, time-delay, non-indicating fuse. It is rated 2.5 A, 600 V AC and 300 V DC. It belongs to the FLSR series and is designed for branch-circuit protection where high inrush currents occur. The manufacturer part number is FLSR02.5.

Where to buy Littelfuse FLSR02.5 fuses worldwide?

3G Electric supplies the Littelfuse FLSR02.5 fuse to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this Class RK5 time-delay fuse.

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

Select a Littelfuse FLSR series fuse by matching the voltage (600 V AC / 300 V DC) and ensuring the amp rating exceeds the motor full-load current by 125–150% for time-delay characteristics. The FLSR02.5 at 2.5 A suits small motors. Always consult the Littelfuse application guide for coordination.
