Eaton FRN-R-70 Fuse - Class RK5, 70 A, 200 kAIC
Part Number: FRN-R-70
Quick Summary
The Eaton FRN-R-70 fuse provides reliable time-delay protection for motor circuits and panel feeders. Engineers frequently battle nuisance trips during startup or surge conditions, which disrupt production and drive up costs. This device is CE marked and part of the RK5 family, offering a robust current-limiting rating up to 200 kAIC and a 70 A amperage rating. Designed for panel builders and machine integrators, it wires quickly via blade-end connections, and its non-indicating design supports compact, service-friendly installations. This combination reduces downtime and supports compliant, reliable electrical protection in industrial environments.

FAQs
The FRN-R-70 is designed for motor control circuits, control panels, and machine feeders where inrush currents occur. Its time-delay characteristic helps protect motors and power distribution equipment from nuisance trips while enabling smooth startup in conveyors, pumps, and automation panels.
The time-delay element allows brief overcurrents typical of motor startup to pass without tripping, reducing unnecessary shutdowns. This yields higher uptime, better process consistency, and less wear on contactors and wiring due to abrupt protections.
The FRN-R-70 is rated for 70 A and 250 Vac (with 125 Vdc support as listed). It provides an interrupt rating of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc, suitable for high-energy fault protection in industrial environments.
Yes, the FRN-R-70 is CE marked. It uses blade-end x blade-end connections for quick, secure installation in standard RK5 fuse holders and panels, enabling straightforward retrofit and panel design.
FRN-R RK5 fuses are non-indicating, so status monitoring should be implemented via remote indicators or panel monitoring. Regular inspection of fuse holders and blade contacts helps ensure reliable protection and minimizes unexpected outages.
