Eaton ER12-800N3PR Rotary Disconnect - Enclosed NEMA 12
Part Number: ER12-800N3PR
Quick Summary
Rotary disconnect switches safely isolate power in industrial electrical panels and motor circuits. The Eaton ER12-800N3PR delivers a robust, enclosed solution for demanding environments, helping prevent accidental energization during maintenance. End users often struggle with inadequate isolation or bulky equipment that slows serviceability; this model addresses that with a pistol-style handle for quick, secure operation and a compact, non-fused design. CE marking and a NEMA 12 enclosure provide confidence in reliability and protection against dust and moisture. Pairing this switch with compatible Bussmann protection devices offers enhanced compliance, streamlined maintenance, and meaningful uptime gains for high-demand applications. The result is safer work practices, faster fault isolation, and measurable total cost of ownership improvements for industrial facilities.

FAQs
The ER12-800N3PR is rated for 600 V and 800 A and features a NEMA 12 enclosure. This combination offers solid protection against dust and moisture in industrial environments while delivering reliable, predictable isolation during maintenance or shutdowns. For compliance, CE marking is included, supporting cross-border installations.
Installation uses a non-fused, enclosed rotary disconnect with a pistol handle designed for quick, secure operation. This reduces lockout times and minimizes the risk of accidental energization, leading to faster maintenance cycles and improved uptime in automated lines. Always verify upstream protection requirements according to your system design.
Yes. The unit is CE marked, indicating conformity with applicable European safety standards. Its 600 V/800 A rating and NEMA 12 enclosure enable reliable operation in diverse climates and installations, from European panels to global switchgear assemblies, provided the integration follows local electrical codes and the upstream protection scheme.
The ER12-800N3PR is a non-fused design, meaning isolation is provided by the switch itself rather than built-in fusing. For complete protection, use appropriate upstream fusing or protective devices within your electrical system. The device is designed to integrate with Eaton Bussmann protection products and is compatible with standard mounting and control wiring practices used in industrial panels.
With its robust 600 V 800 A capability, CE conformity, and NEMA 12 enclosure, the ER12-800N3PR delivers safer maintenance, faster isolation, and reduced downtime. Its non-fused design simplifies spare parts and service workflows, while clear, ergonomic operation lowers operator effort. When paired with compatible protection devices, facilities see improved reliability, easier regulatory compliance, and a lower total cost of ownership over time.
