Product Description

The LITTELFUSE FLSR-ID Series Fuse is a Class RK5, time-delay blade fuse rated at 350 A, 600 V AC and 300 V DC, with an indicating feature. This FLSR350ID component provides overcurrent protection with time-delay characteristics for industrial circuits.

Frequently Asked Questions

What is the LITTELFUSE FLSR350ID fuse used for?

The LITTELFUSE FLSR350ID is a Class RK5, time-delay indicating fuse rated 350 A, 600 V AC / 300 V DC. It protects industrial motor circuits, transformers, and other equipment against overloads and short circuits. The built-in indicator shows when the fuse has opened, simplifying troubleshooting in panel and switchgear applications.

What are the specifications of the LITTELFUSE FLSR350ID?

The LITTELFUSE FLSR350ID is a Class RK5 time-delay fuse from the FLSR-ID series. It is rated 350 A, 600 V AC, and 300 V DC. The indicating feature provides visual confirmation of an open fuse. The manufacturer part number is FLSR350ID, and it is designed for branch-circuit protection in industrial environments.

Where to buy the LITTELFUSE FLSR350ID worldwide?

Contact us for availability and lead time. We source and deliver genuine LITTELFUSE components to support your operations anywhere in the world.

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

To select the correct LITTELFUSE FLSR-ID fuse, match the voltage rating (600 V AC / 300 V DC) and current rating (350 A for the FLSR350ID) to your circuit requirements. Consider the time-delay characteristic for motor-starting applications. Always verify the Class RK5 rejection feature prevents substitution with lower-rated fuses. Consult a qualified engineer for specific coordination studies.
