FAQs
The ER3R-16N6SR is designed for standard control panels and enclosures that accommodate a non-fused, selector rotary disconnect. Use termination methods that match 16 A conductors and 600 V insulation ratings, and ensure mounting inside a NEMA 3R-rated enclosure or better for outdoor installations. Refer to the Eaton specification sheet for dimension guidance and recommended wiring practices to maintain serviceability and safety margins.
Key ratings are 16 A at 600 V with a non-fused, selector operation. It carries a NEMA 3R enclosure rating for outdoor or harsh environments and CE marking for European compliance. This device provides electrical isolation without integrated fusing, which means external fuses or circuit breakers are managed separately within the protection scheme.
Yes. The NEMA 3R rating indicates outdoor or weather-protected indoor use, and CE marking confirms compliance with applicable safety standards. Its non-fused, selector design supports reliability in outdoor machines and equipment control where easy isolation and visibility are essential, while maintaining a compact footprint suitable for rugged installations.
The ER3R-16N6SR carries CE marking, aligning it with European safety and performance standards. Its NEMA 3R enclosure rating provides enclosure protection suitable for outdoor or exposed installations. These certifications matter because they ensure regulatory compliance, safer operation, and smoother cross-border integration for industrial automation projects.
Maintenance is minimized by the non-fused, selector design, which reduces the number of wear components and simplifies isolation procedures. The 600 V, 16 A rating supports compatibility with common motor circuits, improving reliability and reducing unplanned downtime. Over a typical project lifecycle, this leads to lower maintenance labor costs and faster, safer routine servicing of control panels.
