Product Description

The LITTELFUSE FLSR-ID Series FLSR100ID is a Class RK5, time-delay blade fuse rated 100 A at 600 V AC and 300 V DC. This indicating fuse provides visual open-fuse indication for faster troubleshooting in industrial power-distribution circuits.

Frequently Asked Questions

What is the LITTELFUSE FLSR100ID fuse used for?

The LITTELFUSE FLSR100ID is a Class RK5, time-delay, indicating fuse rated 100 A, 600 V AC, 300 V DC. It protects industrial motor circuits, transformers, and branch circuits where high inrush currents occur. The indicating feature provides a visual signal when the fuse opens, simplifying troubleshooting in control panels and switchgear.

What are the specifications of the LITTELFUSE FLSR100ID?

The LITTELFUSE FLSR100ID is a Class RK5, time-delay, indicating fuse from the FLSR-ID Series. It is rated 100 A, 600 V AC, 300 V DC. The manufacturer part number is FLSR100ID. It is designed for overcurrent protection with a visual open-fuse indicator.

Where to buy the LITTELFUSE FLSR100ID worldwide?

You can source the LITTELFUSE FLSR100ID through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine LITTELFUSE components for industrial applications.

How to select the correct LITTELFUSE FLSR-ID fuse for a circuit?

Select the LITTELFUSE FLSR-ID fuse based on the circuit's continuous current rating (e.g., 100 A for the FLSR100ID), voltage (600 V AC or 300 V DC), and inrush characteristics. Time-delay felses handle motor starts. Verify the Class RK5 rejection feature fits your fuse holder. Consult the manufacturer's data sheet for coordination.
