Product Description

The BUSSMANN FRN-R-1/10 is a Class RK5, time-delay cylindrical fuse from the FRN-R Series, rated at 100 mA with 250 V AC and 125 V DC capacity, and is non-indicating. This OEM fuse is designed for overcurrent protection in industrial circuits requiring time-delay characteristics.

Frequently Asked Questions

What is the BUSSMANN FRN-R-1/10 fuse used for?

The BUSSMANN FRN-R-1/10 is a Class RK5 time-delay fuse rated 100 mA at 250 V AC or 125 V DC. It protects motor circuits, transformers, and lighting systems from overloads and short circuits, allowing harmless inrush currents without nuisance opening.

What are the specifications of the BUSSMANN FRN-R-1/10 fuse?

The BUSSMANN FRN-R-1/10 is a non-indicating, time-delay cylindrical fuse from the FRN-R series. It is rated 100 mA, 250 V AC, and 125 V DC. Its Class RK5 design provides high interrupting capacity for industrial branch-circuit protection.

Where to buy the BUSSMANN FRN-R-1/10 fuse worldwide?

3G Electric supplies the BUSSMANN FRN-R-1/10 fuse to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this Class RK5 time-delay fuse.

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

Select a BUSSMANN FRN-R series fuse by matching its voltage rating (250 V AC or 125 V DC) to your system, and choose an amp rating 125–150% of motor full-load current. The time-delay feature prevents tripping on startup inrush. Always consult NEC guidelines.
