Frequently Asked Questions

What is a BUSSMANN FRS-R-8 fuse used for?

The BUSSMANN FRS-R-8 is a Class RK5 time-delay fuse rated 8 A, 600 V AC / 300 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 FRS-R-8 fuse?

The BUSSMANN FRS-R-8 is a non-indicating, time-delay cylindrical fuse from the FRS-R Series. It is rated 8 A, 600 V AC and 300 V DC. The manufacturer part number is FRS-R-8. It is a Class RK5 fuse designed for branch-circuit protection.

Where to buy BUSSMANN FRS-R-8 fuses worldwide?

3G Electric supplies BUSSMANN FRS-R-8 fuses to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial solutions provider, we source genuine BUSSMANN components and support procurement teams across 14 industrial departments.

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

To select the correct BUSSMANN FRS-R fuse, match the voltage rating (600 V AC or 300 V DC) and ensure the amp rating (8 A) exceeds the motor full-load current. The time-delay feature handles startup inrush. Always consult the motor nameplate and local code for proper sizing.
