Frequently Asked Questions

What is the LITTELFUSE FLSR01.8ID fuse used for?

The LITTELFUSE FLSR01.8ID is a Class RK5 time-delay indicating fuse rated 1.8 A, 600 V AC, 300 V DC. It protects motor circuits, transformers, and general industrial equipment from overloads and short circuits. The built-in indicator visually shows when the fuse has opened, simplifying troubleshooting in control panels and machinery.

What are the specifications of the LITTELFUSE FLSR01.8ID?

The LITTELFUSE FLSR01.8ID is a Class RK5 time-delay indicating fuse from the FLSR-ID Series. It is rated 1.8 A, 600 V AC, and 300 V DC. The fuse features a time-delay characteristic for handling inrush currents and an integral indicator that signals a blown fuse. The manufacturer part number is FLSR01.8ID.

Where to buy the LITTELFUSE FLSR01.8ID fuse worldwide?
