Frequently Asked Questions

What is the BUSSMANN FRS-R-8/10 fuse used for?

The BUSSMANN FRS-R-8/10 is a Class RK5 time-delay fuse rated 800 mA, 600 V AC, 300 V DC. It protects motor circuits, transformers, and lighting systems from overloads and short circuits. Its time-delay characteristic handles inrush currents without nuisance opening, making it suitable for industrial and commercial applications where equipment startup surges occur.

What are the specifications of the BUSSMANN FRS-R-8/10 fuse?

The BUSSMANN FRS-R-8/10 is a Class RK5, time-delay, non-indicating cylindrical fuse. It has an 800 mA current rating, 600 V AC and 300 V DC voltage ratings. It belongs to the FRS-R series and carries the manufacturer part number FRS-R-8/10. This fuse is designed for branch circuit protection in industrial equipment.

Where to buy BUSSMANN FRS-R-8/10 fuses worldwide?

You can source BUSSMANN FRS-R-8/10 fuses 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 BUSSMANN components for industrial maintenance and OEM applications.

How to select the correct BUSSMANN FRS-R fuse for an application?

To select the correct BUSSMANN FRS-R fuse, match the voltage rating (600 V AC or 300 V DC) and current rating (800 mA for FRS-R-8/10) to your circuit requirements. Ensure the time-delay characteristic suits motor or transformer inrush. Verify the Class RK5 rejection feature fits your fuse holder. Consult the BUSSMANN application guide for specific load types.
