Frequently Asked Questions

What is the BUSSMANN FRN-R-2 fuse used for?

The BUSSMANN FRN-R-2 is a Class RK5 time-delay fuse rated 2 A, 250 V AC / 125 V DC. It protects motor circuits, lighting, and control transformers against short circuits and sustained overloads. Its time-delay characteristic prevents nuisance opening during inrush currents, making it suitable for industrial and commercial power distribution.

What are the specifications of the BUSSMANN FRN-R-2 fuse?

The BUSSMANN FRN-R-2 is a Class RK5, time-delay, non-indicating cylindrical fuse. It is rated 2 A, 250 V AC and 125 V DC. It belongs to the FRN-R series and is manufactured under part number FRN-R-2. This fuse provides branch-circuit protection with a compact, rejection-style design for safe replacement.

Where to buy BUSSMANN FRN-R-2 fuses worldwide?

3G Electric supplies the BUSSMANN FRN-R-2 fuse to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site.
