Eaton REN-3 Fuse - Time Lag, 3 A - 10 kAIC
Part Number: REN-3
Quick Summary
The Eaton REN-3 Fuse provides time-lag protection for electrical distribution in industrial and commercial facilities. Engineers often wrestle with nuisance trips caused by inrush currents or selecting fuses that tolerate startup surges without compromising protection. This REN-3 is RoHS compliant and designed for reliable 3 A protection at 250 V, with a robust 10 kAIC interrupt rating to safely interrupt faults. While precise CE/SIL/IP certifications aren’t listed in the datasheet, the device aligns with stringent industrial standards and Abb-standard Bussmann lineage for dependable field performance. For procurement and maintenance, this part offers predictable stocking (packaged as 10 per standard) and straightforward ferrule-end connections, delivering long-term value with measured risk reduction and easier asset management.

Eaton Specification Sheet - REN-3
Feature → Business Impact → Application: The REN-3 uses a time-lag, non current-limiting design which minimizes nuisance tripping on inrush, reducing unscheduled downtime and maintenance costs in control panels. This translates to higher line availability for critical processes in industrial facilities and commercial buildings. Application-wise, it is well-suited for electrical protection in distribution panels where inrush currents are common and precise trip curves are needed to protect downstream equipment without false trips. Feature → Business Impact → Application: Ferrule-end connections and standard packaging enable fast, error-free installation and simplified field replacements, lowering commissioning time and labor costs during panel upgrades. Application is practical for retrofit projects and new builds that demand reliable, easily serviceable fuses. Feature → Business Impact → Application: 3 A rating, 250 V, and 10 kAIC interrupt capability provide robust fault handling while maintaining selectivity with upstream protection devices in medium voltage DC/AC circuits, supporting safety, compliance, and uptime in data centers, manufacturing lines, and commercial operations. Feature → Business Impact → Application: RoHS compliance and Class H construction align with modern sustainability and safety protocols, delivering peace of mind for regulated environments and reducing lifecycle risk for OEMs and maintenance teams.

FAQs
Yes. The REN-3 uses ferrule-end connections compatible with standard fuse holders, simplifying replacement during maintenance and reducing the risk of wiring errors. Its standard packaging (10 per unit) supports stocking for panel builds or upgrades and helps minimize downtime when sourcing spares.
REN-3 provides a 3 A amperage rating, 250 V voltage rating, and a 10 kAIC interrupt rating. This combination supports reliable interruption of faults without nuisance trips during inrush events. It enables proper coordination with upstream protection devices, improving selectivity and safeguarding equipment in industrial and commercial panels.
Yes. The time-lag, non current-limiting design tolerates startup surges and inrush currents common in motors and power supplies, preventing unnecessary trips while maintaining protection for downstream devices. This makes it appropriate for distribution panels in manufacturing, processing, and commercial environments.
REN-3 is RoHS compliant, aligning with environmental and regulatory expectations for modern electrical components. The datasheet does not explicitly list CE, IP, or SIL ratings, so verification with the exact installation standard or regional compliance requirements may be necessary for highly regulated projects.
Plan for standard stocking of 10 per pack to support routine replacements and panel refurbishments. The fuse is non-indicating with a classic ferrule-end design, which simplifies visual inspection and quick swaps. Warranty is not applicable on this part, so consider aligning procurement with OEM service agreements for long-term asset reliability.
