Frequently Asked Questions

What is the LITTELFUSE FLSR2.25ID fuse used for?

The LITTELFUSE FLSR2.25ID is a Class RK5 time-delay indicating fuse rated 2.25 A, 600 V AC / 300 V DC. It protects motor circuits, transformers, and general industrial equipment from overcurrent and short circuits. The built-in indicator visually shows when the fuse has opened, simplifying troubleshooting in control panels and machinery.

What are the specifications of the LITTELFUSE FLSR2.25ID fuse?

The LITTELFUSE FLSR2.25ID is a Class RK5 time-delay indicating fuse from the FLSR-ID series. It is rated 2.25 A, 600 V AC, and 300 V DC. The manufacturer part number is FLSR2.25ID. It features a cylindrical body and an integral blown-fuse indicator for quick visual identification of an open circuit.

Where to buy the LITTELFUSE FLSR2.25ID fuse worldwide?

3G Electric supplies the LITTELFUSE FLSR2.25ID fuse to customers worldwide. As a global industrial equipment distributor established in 1990, we handle full logistics, customs clearance, and delivery to your location.
