Product Description

The LITTELFUSE FLNR Series FLNR175 is a Class RK5 time-delay blade fuse rated at 175 A, 250 V AC and 125 V DC. This non-indicating fuse is designed for overcurrent protection in industrial electrical systems, supporting motor and equipment branch circuits where time-delay characteristics are required.

Frequently Asked Questions

What is the LITTELFUSE FLNR175 fuse used for?

The LITTELFUSE FLNR175 is a Class RK5 time-delay fuse rated 175 A, 250 V AC, 125 V DC. It protects industrial motor circuits, transformers, and lighting panels from overloads and short circuits. Its time-delay characteristic allows it to withstand harmless inrush currents without nuisance opening.

What are the specifications of the LITTELFUSE FLNR175 fuse?

The LITTELFUSE FLNR175 is a Class RK5, time-delay, non-indicating fuse rated 175 A, 250 V AC, 125 V DC. It belongs to the FLNR series and carries manufacturer part number FLNR175. It is designed for branch-circuit protection in industrial power distribution systems.

Where to buy the LITTELFUSE FLNR175 fuse worldwide?

3G Electric supplies the LITTELFUSE FLNR175 fuse worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. We source and deliver this Class RK5 time-delay fuse to industrial facilities globally.

How to select the correct LITTELFUSE FLNR175 fuse for an application?

To select the LITTELFUSE FLNR175, verify your circuit voltage does not exceed 250 V AC or 125 V DC, and the continuous load current is below 175 A. Ensure the fuse holder or disconnect switch is rated for Class RK5 fuses. The time-delay feature suits motor or transformer circuits with high inrush.
