Frequently Asked Questions

What is the LITTELFUSE FLNR300ID fuse used for?

The LITTELFUSE FLNR300ID is a Class RK5, time-delay, indicating fuse rated 300 A, 250 V AC, 125 V DC. It protects industrial motor circuits, feeders, and branch circuits against overcurrents. The indicating feature provides a visual signal when the fuse opens, simplifying troubleshooting in panelboards and switchgear.

What are the specifications of the LITTELFUSE FLNR300ID fuse?

The LITTELFUSE FLNR300ID is a Class RK5, time-delay, indicating fuse from the FLNR-ID series. It is rated 300 A, 250 V AC, 125 V DC. The time-delay characteristic allows it to withstand temporary inrush currents without nuisance opening, making it suitable for motor and transformer protection.

Where to buy LITTELFUSE FLNR300ID worldwide?

You can source the LITTELFUSE FLNR300ID fuse through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine LITTELFUSE components for industrial applications.

How to select the correct LITTELFUSE FLNR300ID fuse for an application?

To select the LITTELFUSE FLNR300ID, verify your circuit voltage (250 V AC or 125 V DC max) and continuous current (300 A). Ensure the Class RK5 time-delay characteristic matches your load's inrush profile, such as motors or transformers. Always consult the manufacturer's data sheet for coordination and interrupting rating requirements.
