Frequently Asked Questions

What is the BUSSMANN FRS-R-5 fuse used for?

The BUSSMANN FRS-R-5 is a Class RK5 time-delay cylindrical fuse rated 5 A, 600 V AC, 300 V DC. It protects motor circuits, transformers, and other inductive loads from overcurrent while tolerating harmless inrush currents. Common in industrial control panels, HVAC equipment, and distribution systems.

What are the specifications of the BUSSMANN FRS-R-5 fuse?

The BUSSMANN FRS-R-5 is a Class RK5 time-delay fuse from the FRS-R series. It is rated 5 A, 600 V AC, 300 V DC, non-indicating. The manufacturer part number is FRS-R-5. It provides branch-circuit protection for motor and transformer applications where time-delay is required to avoid nuisance opening.

Where to buy BUSSMANN FRS-R-5 fuses worldwide?

3G Electric supplies BUSSMANN FRS-R-5 fuses worldwide. As a global industrial distributor since 1990, 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 needs.

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

Select the FRS-R fuse based on motor full-load current and starting characteristics. The time-delay feature allows temporary inrush without opening. For a 5 A rating like the FRS-R-5, ensure the continuous load does not exceed 5 A at 600 V AC. Consult NEC Article 430 for sizing guidelines and verify voltage compatibility.
