Frequently Asked Questions

What is the BUSSMANN FRS-R-6-1/4ID fuse used for?

The BUSSMANN FRS-R-6-1/4ID is a Class RK5 time-delay indicating fuse used for overcurrent protection in industrial motor circuits, transformers, and lighting panels. Its time-delay characteristic handles inrush currents without nuisance opening, while the indicating feature shows a blown fuse for faster troubleshooting.

What are the specifications of the BUSSMANN FRS-R-6-1/4ID fuse?

The BUSSMANN FRS-R-6-1/4ID is a Class RK5 time-delay cylindrical fuse rated 6.5 A, 600 V AC, and 300 V DC. It belongs to the FRS-R-ID series with an indicating function. The manufacturer part number is FRS-R-6-1/4ID, and it is designed for branch-circuit protection in industrial applications.

Where to buy BUSSMANN FRS-R-6-1/4ID fuses worldwide?

You can source the BUSSMANN FRS-R-6-1/4ID fuse 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 needs.

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

To select the correct BUSSMANN FRS-R-ID fuse, match the voltage rating (600 V AC or 300 V DC) and ensure the amp rating exceeds the motor full-load current by 125-150% per NEC guidelines. The time-delay feature accommodates startup surges. Verify the Class RK5 rejection clip fits your fuse holder for proper installation.
