Eaton ER12-100N3PR Enclosed Rotary Disconnect - NEMA 12
Part Number: ER12-100N3PR
Quick Summary
The Eaton ER12-100N3PR enclosed rotary disconnect switch provides safe, quick isolation for 600V, 100A industrial circuits. Many plants struggle with reliable line isolation during maintenance, and non-fused designs can complicate safety procedures. It carries CE marking and a NEMA 12 enclosure rating, supporting European and indoor industrial environments. Designed for panel builders and OEMs, this non-fused disconnect streamlines installation, reduces downtime, and simplifies spare-part inventories, delivering predictable operation in harsh manufacturing settings. By pairing a pistol-style handle with durable construction, it minimizes operator fatigue and helps meet arc-flash safety goals. The combination of robust electrical rating and standard documentation supports compliant installations across multiple markets, while keeping field-support and procurement straightforward.

FAQs
For safe and compliant installation, ensure the device is used in an indoor environment consistent with a NEMA 12 enclosure. Verify the system voltage is within 600 V and the current within 100 A. Refer to the provided datasheet for wiring diagrams, torque specifications, and the correct mounting practice to maintain CE compliance and optimal isolation performance.
The switch is explicitly rated for 600 V and 100 A, which aligns with common industrial feeders and control circuits. Its non-fused design supports straightforward isolation in maintenance scenarios, while the NEMA 12 enclosure provides protection against dust and incidental moisture in indoor environments, improving reliability in typical factory settings.
Yes, the ER12-100N3PR is CE marked, indicating conformity with essential European health, safety, and environmental requirements. This facilitates regulatory acceptance across EU markets and simplifies cross-border procurement for panel builders and OEMs deploying multi-region projects.
Yes. Its non-fused, pistol-handle operation provides a clear, safe isolation point suitable for routine shutdowns and lockout/tagout procedures in machine control panels and safety-critical circuits. Ensure the application matches the 600 V / 100 A rating and that proper lockout devices are used for operator safety.
