Eaton Specification Sheet - ER3R-200N3PB
Non-fused operation reduces component wear and simplifies spare parts management, delivering lower maintenance costs and faster replacement cycles in high‑demand environments. Feature → Business Impact → Application: A non-fused design minimizes fuse management and potential nuisance tripping, which translates to reduced downtime during routine maintenance and quicker return to service in continuous‑operation facilities such as packaging lines or conveyors. Application: Fast, reliable isolation in production lines where uptime is critical. Feature → Business Impact → Application: 200 A amperage rating with a 600 V voltage rating provides broad compatibility with medium‑sized drives and motor circuits, enabling safe isolation without oversizing switchgear. Application: Control panels for process equipment and OEM machinery that require robust protection without excessive enclosure size. Feature → Business Impact → Application: NEMA 3R enclosure offers weather resistance and outdoor suitability, improving asset protection in outdoor substations and exterior control cabinets. Application: Outdoor installations where moisture, dust, and incidental exposure are concerns. Feature → Business Impact → Application: Pistol handle design enhances ergonomics and reduces operator error, contributing to safer hand‑off and quicker switch operation. Application: Field service and maintenance tasks where control reliability and operator confidence matter. Feature → Business Impact → Application: CE marking and documented compliance streamline procurement and cross‑site approvals, helping maintenance teams meet regulatory expectations. Application: Auditable installations across distributed facilities with standardized safety practices.

FAQs
Install the ER3R-200N3PB by mounting it to a compatible panel frame with standard mounting provisions, wiring the incoming and outgoing conductors to the appropriate terminals, and securing the pistol handle in the OFF position during final checks. Verify 600 V insulation clearances and confirm enclosure integrity for NEMA 3R exposure. Always follow manufacturer torque specs and local electrical codes.
The device is rated for 200 A and 600 V, non-fused, with a NEMA 3R enclosure. This makes it suitable for mid‑scale motor circuits and control panels that require safe isolation under outdoor or high‑dust conditions, while remaining compact enough for standard switchgear footprints.
Yes. The enclosure is designed to meet NEMA 3R protection, providing weather resistance for outdoor or semi‑outdoor control cabinets. Ensure mounting provisions and cable entries are sealed to maintain enclosure integrity and comply with CE marking requirements.
This unit carries CE marking, indicating conformity with relevant European safety and performance standards. It is also specified as a NEMA 3R enclosure, suitable for weather‑resistant service. For additional compliance needs, verify any site‑specific approval requirements before deployment.
Because the ER3R-200N3PB is non‑fused, consumption of spare fuses is reduced and maintenance cycles can be shorter due to simpler operation. The pistol handle design supports safer, faster switching, which lowers field error rates and downtime, while CE marking and durable enclosure help extend service intervals in harsh environments.
