Frequently Asked Questions

What is the LITTELFUSE FLSR001 fuse used for?

The LITTELFUSE FLSR001 is a Class RK5 time-delay fuse rated 1 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 FLSR001 fuse?

The LITTELFUSE FLSR001 is a Class RK5, time-delay, non-indicating fuse rated 1 A, 600 V AC and 300 V DC. It belongs to the FLSR Series and has a cylindrical body. The manufacturer part number is FLSR001. It is designed for branch-circuit protection where high inrush tolerance is required.

Where to buy LITTELFUSE FLSR001 fuse in worldwide?
