Product Description

The LITTELFUSE FLNR.250T is a Class RK5, time-delay cylindrical fuse from the FLNR Series, rated at 250 mA with 250 V AC and 125 V DC capacity. This non-indicating fuse is designed for overcurrent protection in industrial circuits, sourced and supported by 3G Electric across 14 industrial departments, with specialist expertise in electrical components.

Frequently Asked Questions

What is the LITTELFUSE FLNR.250T fuse used for?

The LITTELFUSE FLNR.250T is a Class RK5 time-delay cylindrical fuse used for overcurrent protection in industrial motor circuits, lighting panels, and control transformers. Its 250 mA rating and 250 V AC / 125 V DC capacity make it suitable for branch-circuit protection in equipment requiring low-current, high-interrupting capability.

What are the specifications of the LITTELFUSE FLNR.250T fuse?

The LITTELFUSE FLNR.250T is a Class RK5, time-delay, non-indicating fuse rated at 250 mA, 250 V AC, and 125 V DC. It belongs to the FLNR series and is designed for motor-start and transformer inrush applications. The manufacturer part number is FLNR.250T, and it is a cylindrical, non-renewable fuse.

Where to buy LITTELFUSE FLNR.250T fuses worldwide?

You can source the LITTELFUSE FLNR.250T 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 maintenance and OEM needs.

How to select the correct LITTELFUSE FLNR.250T fuse for a circuit?

To select the LITTELFUSE FLNR.250T, verify the circuit voltage (max 250 V AC or 125 V DC) and continuous current (250 mA). Use a Class RK5 time-delay fuse for motor or transformer circuits with high inrush. Ensure the interrupting rating meets system fault current. Consult the FLNR series datasheet for coordination with upstream breakers.
