Eaton FRN-R-40 Fuse - RK5 Class, 40A, 200 kAIC
Part Number: FRN-R-40
Quick Summary
The Eaton FRN-R-40 fuse provides time-delay overload protection for control circuits in industrial equipment. In many plants, nuisance trips during startup surges disrupt production and complicate maintenance; a robust fuse like FRN-R-40 reduces downtime and extends equipment life. CE marking confirms European safety compliance for this RK5-class fuse, and its dual-element, current-limiting design offers reliable operation across dynamic loads. This solution also aligns with industry expectations for finger-safe protection and easy field replacement, while supporting standard ferrule-end connections. For procurement, the 40 A rating delivers a balance of protection and cost, with a well-documented data sheet and compatibility with Bussmann-series catalogs.

FAQs
FRN-R-40 uses ferrule-end connections and follows the RK5 format, allowing seamless installation in standard RK5 fuse holders. The ferrule-end design supports quick, reliable replacement in control panels and enclosures, with a 3 inch overall length and a compact footprint that fits typical tray and panel layouts.
The fuse is rated at 40 A with interrupt ratings of 200 kAIC at 250 VAC and 20 kAIC at 125 VDC. It is a time-delay, dual-element, current-limiting device with a 10 second response at 500% overload, making it suitable for motors and circuits with short surges while protecting downstream components.
Yes. The time-delay, dual-element RK5 fuse provides reliable protection during startup surges while avoiding nuisance trips on normal inrush. Its 40 A rating and high interrupt capacity support motor circuits and drives in industrial panels, reducing downtime and extending equipment life.
The product is CE marked, indicating compliance with European safety standards. Other certifications are not listed in the provided data; for additional regulatory requirements, consult regional safety and compliance guidelines and the Bussmann catalogs.
Finger-safe construction, non-indicating operation, and ferrule-end connections simplify maintenance and field replacement, reducing service time. The robust interrupt ratings and time-delay performance improve uptime, while compatibility with standard RK5 holders and Bussmann catalogs streamlines procurement and inventory management.
