Frequently Asked Questions

What is the LITTELFUSE FLSR500ID fuse used for?

The LITTELFUSE FLSR500ID is a Class RK5, time-delay indicating fuse rated 500 A, 600 V AC, 300 V DC. It protects industrial motor circuits, transformers, and other equipment against overloads and short circuits, with visual indication for blown fuse identification.

What are the specifications of the LITTELFUSE FLSR500ID?

The LITTELFUSE FLSR500ID is from the FLSR-ID Series, a Class RK5 time-delay blade fuse. It has a current rating of 500 A, voltage rating of 600 V AC and 300 V DC, and includes an indicating feature that shows when the fuse has opened.

Where to buy the LITTELFUSE FLSR500ID worldwide?

You can source the LITTELFUSE FLSR500ID through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring the fuse reaches your facility reliably.

How to select the correct LITTELFUSE FLSR500ID fuse for an application?

To select the correct LITTELFUSE FLSR500ID, verify your circuit's voltage (600 V AC or 300 V DC max) and continuous current (500 A). Ensure the Class RK5 time-delay characteristic matches your motor or transformer starting requirements. Consult the FLSR-ID series datasheet for coordination details.
