Frequently Asked Questions

What is the BUSSMANN FRN-R-1 fuse used for?

The BUSSMANN FRN-R-1 is a Class RK5 time-delay fuse rated 1 A at 250 V AC or 125 V DC. It protects motor circuits, transformers, and lighting systems from overloads and short circuits, allowing harmless temporary inrush currents without nuisance opening.

What are the specifications of the BUSSMANN FRN-R-1 fuse?

The BUSSMANN FRN-R-1 is a non-indicating, time-delay cylindrical fuse from the FRN-R series. It is rated 1 A, 250 V AC and 125 V DC. Its Class RK5 design provides high interrupting capacity for branch-circuit protection in industrial control panels and distribution equipment.

Where to buy BUSSMANN FRN-R-1 fuses worldwide?

3G Electric supplies the BUSSMANN FRN-R-1 fuse to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time — we source genuine BUSSMANN components for industrial maintenance and OEM applications globally.

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

Select a BUSSMANN FRN-R series fuse with an amp rating 125–150% of the motor full-load current for time-delay coordination. Verify the voltage rating (250 V AC or 125 V DC) matches your system. The FRN-R-1 at 1 A suits small motors or control transformers. Always consult NEC guidelines for branch-circuit protection.
