Frequently Asked Questions

What is the LITTELFUSE FLSR020 fuse used for?

The LITTELFUSE FLSR020 is a Class RK5 time-delay fuse rated 20 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 HVAC equipment.

What are the specifications of the LITTELFUSE FLSR020 fuse?

The LITTELFUSE FLSR020 is a Class RK5, time-delay, non-indicating fuse. It is rated 20 A, 600 V AC, and 300 V DC. It belongs to the FLSR series and carries the manufacturer part number FLSR020. This cylindrical fuse is designed for branch-circuit protection where high inrush tolerance is required.
