Eaton ER1-100N3PR Enclosed Rotary Disconnect - 600V NEMA 1
Part Number: ER1-100N3PR
Quick Summary
The Eaton ER1-100N3PR is an enclosed rotary disconnect switch used to safely isolate 100 A circuits in electrical enclosures. When panel space is tight or downtime is costly, operators struggle with bulky, unfused disconnects; this unit provides a compact, non-fused solution with a pistol handle. Key ratings include a NEMA 1 enclosure, 600 V maximum and 100 A capacity, enabling reliable isolation in industrial control cabinets. Designed to integrate with RDF30CC switches, it simplifies maintenance scheduling, supports code-compliant installations, and reduces spare parts through a non-fused design. As part of the Eaton Bussmann series, it delivers durable electrical protection for automation systems, while keeping installation straightforward for technicians.
