Frequently Asked Questions

What is the LITTELFUSE FLNR175ID fuse used for?

The LITTELFUSE FLNR175ID is a Class RK5 time-delay fuse rated 175 A at 250 V AC or 125 V DC. It is used for motor and transformer protection in industrial power distribution, providing overload and short-circuit protection with an indicating feature for blown fuse identification.

What are the specifications of the LITTELFUSE FLNR175ID?

The LITTELFUSE FLNR175ID is part of the FLNR-ID series, a Class RK5 time-delay blade fuse. It is rated 175 A, 250 V AC, and 125 V DC. The indicating function shows when the fuse has opened, simplifying maintenance in industrial control panels and switchgear.

Where to buy the LITTELFUSE FLNR175ID fuse worldwide?

You can source the LITTELFUSE FLNR175ID fuse worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this LITTELFUSE part.

How to select the correct LITTELFUSE FLNR175ID fuse for an application?

To select the LITTELFUSE FLNR175ID, verify your circuit voltage (250 V AC or 125 V DC max) and continuous current (175 A). This time-delay fuse handles motor inrush without nuisance tripping. Ensure the Class RK5 rejection base matches the fuse dimensions. Consult the FLNR-ID series datasheet for coordination.
