Frequently Asked Questions

What is a BUSSMANN FRS-R-350 fuse used for?

The BUSSMANN FRS-R-350 is a Class RK5 time-delay fuse rated 350 A at 600 V AC or 300 V DC. It protects motors, transformers, and other inductive loads from short circuits and sustained overloads in industrial power distribution and control panels.

What are the specifications of the BUSSMANN FRS-R-350 fuse?

The BUSSMANN FRS-R-350 is a non-indicating, time-delay blade fuse from the FRS-R series. It is rated 350 A, 600 V AC, and 300 V DC. Its Class RK5 design provides high interrupting capacity for branch-circuit protection in industrial equipment.

Where to buy a BUSSMANN FRS-R-350 fuse worldwide?

3G Electric supplies the BUSSMANN FRS-R-350 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 right BUSSMANN FRS-R fuse for an application?

Select the BUSSMANN FRS-R fuse based on continuous load current (typically 125% of motor FLA), available fault current, and voltage rating. For 350 A circuits at 600 V AC or 300 V DC, the FRS-R-350 provides time-delay characteristics to handle inrush without nuisance opening.
