Frequently Asked Questions

What is the LITTELFUSE FLSR075 fuse used for?

The LITTELFUSE FLSR075 is a Class RK5 time-delay fuse rated 75 A, 600 V AC / 300 V DC. It protects motors, transformers, and other inductive loads from short circuits and sustained overloads. Its time-delay characteristic prevents nuisance opening during inrush currents, making it suitable for industrial control panels and power distribution.

What are the specifications of the LITTELFUSE FLSR075 fuse?

The LITTELFUSE FLSR075 is a Class RK5, time-delay, non-indicating fuse rated 75 A, 600 V AC and 300 V DC. It belongs to the FLSR series and is manufactured by LITTELFUSE. The part number is FLSR075. It is designed for branch-circuit protection in industrial equipment requiring high interrupting capacity.

Where to buy LITTELFUSE FLSR075 worldwide?

Contact us for availability and lead time. We source and deliver genuine LITTELFUSE components to support your maintenance and production needs.

How to select the correct LITTELFUSE FLSR series fuse for an application?

Select the FLSR series fuse based on continuous load current (75 A for FLSR075), system voltage (600 V AC or 300 V DC), and available fault current. The time-delay characteristic handles motor starting inrush. Verify the fuse class (RK5) matches your fuse holder. Consult LITTELFUSE application notes for coordination with upstream devices.
