Eaton ER1-80N3PB Enclosed Rotary Disconnect - NEMA 1
Part Number: ER1-80N3PB
Quick Summary
The Eaton ER1-80N3PB is an enclosed rotary disconnect switch used for safe electrical isolation in distribution panels. Engineers often struggle with space constraints and the complexity of sourcing reliable non-fused disconnects. This unit is CE marked and rated for NEMA 1 enclosures, delivering safety and compatibility in indoor installations. With a 600 V rating and 80 A capacity, it provides scalable control isolation while minimizing spare parts and downtime. The pistol-style handle supports ergonomic operation in control panels, and the non-fused design reduces maintenance complexity by eliminating fusing components where not required. This combination is particularly valuable in machine building and panel-building agencies seeking reliable isolation, CE compliance, and fast, error-free installation.

FAQs
Yes. The ER1-80N3PB is CE marked and designed for NEMA 1 indoor enclosures, providing compliant protection for general purpose control panels and equipment in indoor industrial environments.
Installers should mount the unit in a suitable control panel with adequate clearance for the pistol-style handle, ensure proper wiring separation from high-energy conductors, and verify alignment with the non-fused, non-simultaneous disconnect operation to maintain safe isolation during maintenance.
ER1-80N3PB is a non-fused disconnect, which simplifies maintenance, reduces spare parts stock, and lowers the risk of fuse-related nuisance trips. It provides reliable isolation while avoiding fuse management where not required, ideal for streamlined panel installations.
Typical applications include control panels for machines, switchgear in manufacturing lines, and process automation enclosures where safe, indoor isolation is required and 600 V/80 A capabilities cover the circuit needs.
Operating without fuses reduces component counts and spare parts inventory, lowers downtime during maintenance, and delivers predictable disconnect action with ergonomic pistol-handle design, contributing to shorter maintenance windows and improved overall equipment availability.
