Frequently Asked Questions

What is the BUSSMANN FRS-R-8ID fuse used for?

The BUSSMANN FRS-R-8ID is a Class RK5 time-delay indicating fuse rated 8 A, 600 V AC / 300 V DC. It protects motor circuits, transformers, and other inductive loads where temporary inrush currents occur. The indicating feature provides a visual signal when the fuse opens, simplifying troubleshooting in industrial control panels and distribution equipment.

What are the specifications of the BUSSMANN FRS-R-8ID fuse?

The BUSSMANN FRS-R-8ID is a Class RK5 time-delay cylindrical fuse from the FRS-R-ID series. It is rated 8 A, 600 V AC and 300 V DC. The indicating function shows a visual flag when the fuse has opened. The manufacturer part number is FRS-R-8ID. It is designed for overcurrent protection in industrial applications.

Where to buy the BUSSMANN FRS-R-8ID fuse worldwide?

3G Electric supplies the BUSSMANN FRS-R-8ID fuse worldwide. As a global industrial equipment distributor established in 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. We source and deliver genuine BUSSMANN components to industrial buyers globally.

How to select the correct BUSSMANN FRS-R-ID series fuse for my application?

Select the BUSSMANN FRS-R-ID fuse based on your circuit voltage (600 V AC or 300 V DC maximum) and continuous load current. The time-delay characteristic handles motor start-up surges. Choose an amp rating equal to or slightly above the full-load current. For indicating fuses, verify the visual flag is visible after installation. Consult BUSSMANN application notes for specific motor protection sizing.
