Product Description

The BUSSMANN FRN-R-8 is a Class RK5, time-delay cylindrical fuse from the FRN-R Series, rated at 8 A with 250 V AC and 125 V DC capacity. It is a non-indicating fuse designed for overcurrent protection in industrial electrical systems.

Frequently Asked Questions

What is the BUSSMANN FRN-R-8 fuse used for?

The BUSSMANN FRN-R-8 is a Class RK5 time-delay cylindrical fuse rated 8 A, 250 V AC / 125 V DC. It protects motor circuits, transformers, and lighting panels from overloads and short circuits. Its time-delay characteristic allows it to withstand harmless inrush currents without nuisance opening.

What are the specifications of the BUSSMANN FRN-R-8 fuse?

The BUSSMANN FRN-R-8 is a Class RK5, time-delay, non-indicating fuse rated 8 A, 250 V AC and 125 V DC. It belongs to the FRN-R Series and is manufactured under part number FRN-R-8. It is designed for branch-circuit protection in industrial control panels and motor starters.

Where to buy the BUSSMANN FRN-R-8 fuse worldwide?

3G Electric supplies the BUSSMANN FRN-R-8 fuse worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time. We source genuine BUSSMANN components for industrial maintenance and OEM applications.

How to select the correct BUSSMANN FRN-R fuse for a motor circuit?

Select the BUSSMANN FRN-R fuse based on motor full-load current and starting characteristics. For a motor drawing 8 A, the FRN-R-8 provides time-delay to handle startup inrush. Always verify voltage rating (250 V AC / 125 V DC) and ensure the fuse is Class RK5 for branch-circuit protection. Consult NEC Article 430 for sizing.
