Eaton FRN-R-17-1/2 Fuse - RK5 Class, CE Marked
Part Number: FRN-R-17-1/2
Quick Summary
The Eaton Bussmann FRN-R-17-1/2 fuse provides time-delay protection for electrical circuits in industrial equipment. Many systems experience nuisance trips during motor starts or inrush events, driving up maintenance costs and downtime. This device is CE marked and belongs to the RK5 fuse family, offering robust interrupting ratings (200 kAIC at 250 Vac and 20 kAIC at 125 Vdc) for demanding loads. It is a dual-element, time-delay fuse with non-indicating status and ferrule-end connections, designed for easy replacement in standard Bussmann RK5 holders. The combination of reliable protection, straightforward installation, and compatible form factor supports streamlined procurement, improved asset protection, and reduced spare-part inventory in manufacturing and automation environments.

Feature → Business Impact → Application: The FRN-R-17-1/2 is a time-delay, dual-element, current-limiting fuse that withstands inrush without nuisance triggering, reducing unplanned downtime and extending equipment life in motor drives and conveyors. This translates to measurable uptime gains and safer startup sequences in automation panels and machine control enclosures. Feature → Business Impact → Application: With a 17.5 A rating and 250 Vac / 125 Vdc compatibility, it delivers precise, predictable protection for mixed-supply systems, enabling engineers to design flexible power distribution and avoid overspecifying components in electrical panels. Feature → Business Impact → Application: The RK5 class and ferrule-end connections ensure quick, reliable installation in standard Bussmann RK5 holders, lowering labor time during panel refits and spares stocking for field service. Feature → Business Impact → Application: A non-indicating fuse minimizes indicator wear and panel clutter while CE marking confirms compliance for European installations, streamlining procurement and reducing compliance risk in industrial environments. Feature → Business Impact → Application: The 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc interrupt ratings protect feeders and control circuits against short circuits, enabling safer Heretofore costly fault restoration and improved overall system resilience in manufacturing and process automation.

FAQs
Install FRN-R-17-1/2 using standard ferrule-end contacts into an RK5 fuse holder. Verify the enclosure has adequate clearance, then align the ferrule ends with the holder slots and press firmly until seated. Ensure the panel is de-energized during replacement and check tightness after installation to maintain reliable contact and thermal performance.
The FRN-R-17-1/2 provides 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc. It is rated for 250 Vac and 125 Vdc, making it suitable for mixed-voltage environments in industrial controls, motor circuits, and power distribution panels.
Yes. As a time-delay, dual-element fuse, FRN-R-17-1/2 accommodates inrush currents typical of motor starts, reducing nuisance trips while preserving effective overcurrent protection in automated machinery and conveyors.
FRN-R-17-1/2 is CE Marked, indicating conformity with European safety directives for electrical equipment. It belongs to the Class RK5 family, which is a recognized industry standard for Bussmann RK5 fuses used in control and power circuits.
Yes. Its non-indicating design minimizes indicator wear and simplifies panel layout, while the time-delay, current-limiting protection reduces fault propagation and downtime, contributing to lower maintenance costs and improved ROI in automated manufacturing lines.
