Frequently Asked Questions

What is the LITTELFUSE FLSR2.25 fuse used for?

The LITTELFUSE FLSR2.25 is a Class RK5 time-delay fuse rated 2.25 A, 600 V AC / 300 V DC. It protects motor circuits, transformers, and lighting systems from overcurrent and short circuits. Its time-delay characteristic handles inrush currents without nuisance opening, making it suitable for industrial and commercial power distribution.

What are the specifications of the LITTELFUSE FLSR2.25?

The LITTELFUSE FLSR2.25 is a Class RK5, time-delay, non-indicating fuse. It has a current rating of 2.25 A, voltage rating of 600 V AC and 300 V DC, and belongs to the FLSR series. The manufacturer part number is FLSR2.25. It is designed for overcurrent protection in branch circuits.

Where to buy the LITTELFUSE FLSR2.25 fuse worldwide?

You can source the LITTELFUSE FLSR2.25 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 FLSR2.25 fuse for a circuit?

To select the LITTELFUSE FLSR2.25, verify the circuit's continuous current does not exceed 2.25 A and the system voltage is within 600 V AC or 300 V DC. Ensure the fuse's Class RK5 time-delay characteristic matches the inrush profile of your load, such as motors or transformers. Consult a qualified engineer for coordination.
