Frequently Asked Questions

What is a Littelfuse FLSR-ID time-delay fuse used for?

The Littelfuse FLSR-ID series time-delay fuse protects motor circuits and other inductive loads from overcurrent. Its 4.5 A rating and 600 V AC / 300 V DC capacity suit industrial control panels and power distribution. The indicating feature allows quick visual identification of a blown fuse, reducing downtime.

What are the specifications of the Littelfuse FLSR04.5ID fuse?

The Littelfuse FLSR04.5ID is a Class RK5, time-delay, indicating fuse rated 4.5 A, 600 V AC, and 300 V DC. It belongs to the FLSR-ID series and features a cylindrical body. The indicating function shows a blown fuse via a window or flag, aiding maintenance in industrial equipment.

Where to buy Littelfuse FLSR04.5ID fuses worldwide?

3G Electric supplies the Littelfuse FLSR04.5ID fuse to customers worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this Class RK5 time-delay indicating fuse.

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

Select a Littelfuse FLSR-ID fuse by matching its voltage (600 V AC / 300 V DC) and current rating (e.g., 4.5 A) to your motor's full-load amps. Time-delay fuses tolerate startup inrush without nuisance opening. Verify the interrupting rating meets system fault current. Consult a qualified engineer for branch-circuit protection.
