Eaton Specification Sheet - ER1-1200N3PB
Enclosed, non-fused rotary disconnect design reduces arc flash risk while delivering clear mechanical isolation. This translates to safer maintenance windows and fewer unexpected shutdowns in live electrical rooms. Ideal for indoor distribution panels in manufacturing environments. 600 V and 1200 A rating enables reliable handling of high-demand loads without over-sizing switchgear. This improves panel footprint efficiency and lowers total cost of ownership. Suitable for motor control centers and large control panels. Pistol handle offers ergonomic operation and quick, lockable off positioning. Operators gain faster switch tasks and improved compliance with lockout/tagout procedures. Compatible with common control schemes in Eaton Bussmann series. NEMA 1 enclosure provides indoor moisture and dust protection suitable for standard plant environments. The rugged construction supports long service life in continuous duty applications. Minimal maintenance and straightforward replacement for aging installations. Used with RDF30J-_-COMP switches ensures plug-and-play compatibility within Eaton protection ecosystem. This simplifies retrofits and reduces field engineering time. Integrated lifecycle support reduces downtime and total cost. Non-fused configuration avoids unnecessary fusing components, cutting upfront costs and simplifying wiring. Engineering teams can standardize on a single family of protection devices. The result is improved reliability, faster commissioning, and a clearer path to regulatory compliance.
