Eaton Specification Sheet - ER4-25N6SR
Feature → Business Impact → Application: The ER4-25N6SR provides a non-fused selector option, reducing fuse maintenance and replacing time while maintaining clear, deliberate operator control; this translates to lower maintenance costs and safer work procedures in automated lines. Application: Use in control panels and machine environments where rapid, safe isolation is required during servicing, with minimal downtime and reduced risk of accidental energization. Feature → Business Impact → Application: NEMA 4 enclosure protects against moisture, dust, and light splashing, increasing uptime in harsher factory settings; this supports compliance with industrial environmental standards and extends service intervals. Application: Suitable for outdoor or exposed indoor installations where weather or wash-down conditions are factors. Feature → Business Impact → Application: 600 V / 25 A rating provides robust compatibility with common industrial control circuits, enabling straightforward integration with existing electrical infrastructure and Bussmann series components. Application: Ideal for service entry disconnects and local isolation points in panel assemblies, where predictable performance and quick installation matter. Feature → Business Impact → Application: Enclosed design with visible red actuator improves fault identification and operator awareness, reducing misoperation and improving safety metrics in high-mix, high-volume production environments. Application: Great for aerospace, automotive, and general manufacturing facilities that require reliable, code-conscious disconnects. Feature → Business Impact → Application: CE marking and documented compliance support regulatory alignment for multiple markets, simplifying procurement and audit processes. Application: Procurement teams can standardize on a single, CE-certified solution for multinational projects, reducing vendor fragmentation and stocking costs.
