Eaton FRS-R-8ID Fuse - Class RK5 protection, 600 Vac
Part Number: FRS-R-8ID
Quick Summary
The Eaton FRS-R-8ID fuse provides time-delay protection for industrial control panels and branch circuits. Users often wrestle with nuisance inrush trips and costly downtime, so this RK5 fuse balances selectivity and fast clearing. CE marked for global acceptance, its 600 Vac rating and 200 kAIC interrupt capability support modern safety and reliability standards. Designed for compatibility with ferrule-end wiring and standard packaging, it helps engineers meet tight project timelines while reducing total cost of ownership. Additionally, dual-element design improves short-circuit resilience; its 8 A rating matches common control-circuit loads, and the compact 5 in length supports dense panel layouts. The documentation and variant options streamline acceptance testing and field service.

Time-delay, dual-element design provides extended clearance for motor inrush and transformer surges. This reduces nuisance trips, improves equipment uptime, and supports safe startup sequences in control panels and machine centers. Current-limiting capability protects wiring and downstream devices by limiting fault energy to predictable levels, resulting in reduced arc flash risk and minimized collateral damage in branch circuits powering drives and sensors in industrial automation. High interrupt rating delivers robust protection for high-energy faults; 200 kAIC at 600 Vac ensures safe interruption in main feeders and critical circuits, enabling more resilient power distribution in manufacturing environments. Ferrule-end to ferrule-end connection and a standard 5 in length simplify panel mounting and field replacement, minimizing installation time and ensuring reliable terminations in compact enclosures. Fuse indicator options, including non-indicating and indicating variants, support faster fault location during service, while CE marking underpins global compliance across sites and supply chains. The overall solution aligns with long-term maintenance strategies and supports cost-of-ownership reduction through predictable lifecycle performance.

FAQs
The FRS-R-8ID uses ferrule-end terminations and a standard 5 in body length, enabling straightforward drop-in replacement in most RK5-class panel boards and modular enclosures. Ensure mounting clearance for the 0.81 in width and 0.81 in height, and verify compatibility with ferrule sizes used by your terminal blocks to avoid termination stress.
Key figures include an 8 A amperage rating, 600 Vac maximum voltage, and 200 kAIC interrupt rating at 600 Vac with a 10 s response at 500% overcurrent. These specs support rapid fault clearing while tolerating normal inrush in control circuits, reducing both downtime and downstream component stress.
Yes. The time-delay, dual-element design suits motor and drive protection by allowing inrush currents to pass without nuisance trips while still providing fast fault clearance for short-circuit events, protecting motor windings, starters, and contactors in automation platforms.
This fuse carries CE marking for global compliance. It belongs to the Class RK5 family, which defines its design and performance expectations for branch-circuit protection in electrical protection and control applications.
With its high interrupt rating and robust construction, the FRS-R-8ID reduces unplanned downtime and damage to downstream equipment. Its ferrule-end terminations, compact form factor, and clear datasheets streamline installation and field servicing, supporting lower maintenance costs and faster project commissioning.
