Eaton ER3R-25N3PR Enclosed Rotary Disconnect - NEMA 3R
Part Number: ER3R-25N3PR
Quick Summary
ER3R-25N3PR is an enclosed rotary disconnect switch that safely isolates power in industrial control panels. A common pain point is achieving fast, lockable isolation without sacrificing reliability or increasing downtime. This unit carries CE certification and a NEMA 3R enclosure rating, suitable for outdoor or damp environments, and supports up to 600 V and 25 A. With a non-fused design and a pistol-style handle, it delivers predictable operation and straightforward maintenance. By simplifying isolation sequences, it reduces arc-flash exposure and helps meet safety protocols. For controls teams, this means better uptime, easier audits, and a clear path to compliant switchgear integration.

Eaton Specification Sheet - ER3R-25N3PR
Enclosed rotary design protects operators and components, reducing dust ingress and environmental exposure while enabling safe, lockable isolation in crowded panels. This directly improves reliability and reduces maintenance cycles for mission-critical equipment used in manufacturing and processing lines. The non-fused configuration with a pistol-style handle delivers intuitive operation and faster fault response, which translates into shorter downtime during routine maintenance and faster response during outages. The 600 V, 25 A rating paired with a NEMA 3R enclosure supports both indoor and outdoor or damp environments, expanding installation options from single-bay control desks to outdoor substations. CE marking ensures regulatory compliance for European and global projects, streamlining cross-border procurement and audit readiness. A compact, rugged form factor supports tight panel layouts and retrofits, reducing the total cost of ownership across multiple assemblies. These characteristics collectively deliver improved safety, operational efficiency, and long-term reliability for industrial protection and control applications.

FAQs
The ER3R-25N3PR is designed for up to 600 V and 25 A circuits, suitable for motor control centers and control panels. It uses a non-fused design with a pistol-style handle and is CE marked, with a NEMA 3R enclosure for indoor or outdoor/damp applications. It integrates into standard panel architectures using common mounting and wiring practices, reducing integration time in new builds or retrofits.
Install the ER3R-25N3PR within an appropriate enclosure that meets its NEMA 3R rating. Ensure the operating handle is accessible for normal operation and lockout/tagout procedures. Follow standard electrical installation practices for non-fused disconnects, verify voltage and current ratings, and route wiring to maintain clearances and safe isolation paths during maintenance.
Yes. The device carries a NEMA 3R enclosure rating, which is designed for outdoor and damp environments. Combined with CE marking, it provides reliable protection for disconnection operations in harsher conditions, helping maintain safety and uptime in outdoor control panels and exposed installations.
The ER3R-25N3PR is CE marked and rated NEMA 3R, indicating compliance with European regulatory requirements and suitability for protected outdoor or damp environments. The non-fused design and pistol handle support safe operation, while the 600 V/25 A ratings align with common industrial control applications.
The non-fused design reduces fuse-related maintenance and stock requirements, while the pistol handle enables quicker, safer operation during lockout/tagout. Its rugged enclosure protects against dust and moisture, lowering unexpected outages and extending service life of downstream equipment, which translates to shorter downtime, fewer spare parts, and improved maintenance efficiency.
