Eaton BP/FRN-R-35 Fuse - Class RK5, CE Marked
Part Number: BP/FRN-R-35
Quick Summary
Eaton BP/FRN-R-35 fuse provides time-delay current-limiting protection for industrial electrical distributions. Engineers often battle nuisance fuse blows during motor startup or transient events, driving unnecessary downtime. With CE Marking, RK5 class designation, and high interrupt ratings of 200 kAIC Vac / 20 kAIC Vdc, it meets European and North American standards for critical loads. Compact ferrule-end construction and blister packaging support faster installation and streamlined procurement in panel shops. The 3 in length and equal cross-section simplify mounting in tight control cabinets, while standard ferrule terminations ensure reliable connections with common lugs. This combination reduces maintenance costs and inventory complexity by aligning with a single, compatible FRN-R family portion.

Eaton Specification Sheet - BP/FRN-R-35
Time-delay current-limiting design provides selective protection that accommodates motor inrush and transient loads, reducing nuisance trips while maintaining circuit safety; this translates to fewer production interruptions and lower maintenance costs in motor control circuits and power distribution panels. Dual-element construction enhances protection accuracy and reliability in harsh industrial environments, supporting longer equipment life and improved uptime for processes that demand stable fault-clearing performance. RK5 class designation offers interchangeability with a wide range of Bussmann FRN-R fuses and panelboard inventories, simplifying procurement and service in switchgear and control cabinets. Ferrule-end terminations enable quick, secure connections with standard lugs and crimp tools, speeding installation and reducing field wiring time on assembly lines and retrofit projects. At 35 A with 200 kAIC Vac and 20 kAIC Vdc ratings, this fuse delivers robust short-circuit protection for feeders and motor starters in high-current drives, with reliable performance under fault conditions. Blister-pack packaging and a compact 3 in length support streamlined stocking and easy field handling, while non-indicating design minimizes maintenance for sealed enclosures in cleanroom or food-and-beverage environments. The rejection-style feature helps ensure correct fuse mounting only in compatible holders, reducing incorrect replacements in automated lines and service fleets.

FAQs
The BP/FRN-R-35 uses ferrule-end connections, simplifying mounting in compatible terminal blocks. Ensure ferrule size matches the lugs and tighten to the manufacturer’s torque specification. With a 3 in length and a 0.81 in cross-section, position the fuse to avoid interference with adjacent components. Use the blister-pack packaging to keep spares organized and readily accessible in standard panels.
A 35 A rating denotes the continuous operating current the fuse is designed to carry before tripping. The 200 kAIC Vac / 20 kAIC Vdc interrupt ratings indicate the maximum fault current the fuse can safely interrupt in AC and DC circuits. Together, they support protection of motors and feeders against short circuits while tolerating startup inrush, reducing downtime and equipment damage.
Yes. The BP/FRN-R-35 is a Class RK5 fuse designed for RK5-compatible holders and Bussmann FRN-R family installations. Its standardized RK5 form factor and ferrule-end terminations enable straightforward substitution within existing protection schemes, aiding maintenance teams in achieving quick replacements and consistent protection across panels and switchgear.
BP/FRN-R-35 carries CE marking, indicating compliance with relevant EU safety and performance requirements. This is crucial for installations in European markets and ensures alignment with regional electrical protection standards. CE marking, combined with RK5 classification, supports cross-border procurement and reduces compliance risk in multinational manufacturing environments.
The 35 A time-delay fuse reduces nuisance trips during motor start-up, cutting downtime and maintenance costs. Its robust interrupt ratings protect critical feeders from faults, lowering replacement expenses. Interchangeability with RK5 inventories simplifies stocking, while ferrule-end connections speed installation, reducing labor costs. Overall, expect improved uptime and lower total cost of ownership in panel-based protection schemes.
