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, transformers, and lighting panels from overloads and short circuits. Its 3.5 A rating and 600 V AC / 300 V DC capacity suit industrial control panels and power supplies. The indicating feature shows a blown fuse for faster troubleshooting.

What are the specifications of the Littelfuse FLSR03.5ID fuse?

The Littelfuse FLSR03.5ID is a Class RK5, time-delay, indicating fuse rated 3.5 A, 600 V AC, and 300 V DC. It belongs to the FLSR-ID series and features a cylindrical body. The indicating function provides visual confirmation when the fuse opens, aiding maintenance in industrial equipment.

Where to buy Littelfuse FLSR03.5ID fuses worldwide?

3G Electric supplies the Littelfuse FLSR03.5ID 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 on this Class RK5, time-delay, indicating fuse for your motor or transformer protection needs.

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

Select a Littelfuse FLSR-ID fuse by matching the motor full-load current and starting characteristics. For a 3.5 A motor, use the FLSR03.5ID for time-delay to handle inrush. Verify voltage rating (600 V AC / 300 V DC) and ensure the fuse is Class RK5 for branch-circuit protection. Consult a qualified engineer for coordination.
