FAQs
The ER3R-80N6SR is designed for industrial control panels, motor control centers, and service disconnect points. Its enclosed, non-fused, selector configuration plus a NEMA 3R rating makes it suitable for both indoor and outdoor environments, including areas with exposure to weather, dust, or moisture. This supports safer maintenance and consistent shutdown procedures in complex line layouts.
CE marking indicates compliance with applicable European health, safety, and environmental requirements, enabling use across many international markets. For the ER3R-80N6SR, this means the product meets essential EU standards for electrical equipment, facilitating global deployment in regulated facilities and helping procurement teams meet import and safety regulations without additional local certification.
Yes. The unit is specified with a NEMA 3R enclosure, which provides protection against falling rain, sleet, and other weather conditions, making it suitable for outdoor installations and exposed indoor locations. This reduces concerns about enclosure integrity during routine maintenance and in exposed electrical cabinets.
The non-fused selector design simplifies the control circuit and reduces the number of spare fuse components required. This translates to lower inventory costs and faster maintenance cycles, as technicians can isolate, test, and re-energize circuits quickly without navigating fuse replacements or complex fuse configurations.
Yes. The ER3R-80N6SR is part of Eaton's Bussmann series integrated line, ensuring compatibility with standard Bussmann catalogs and installation practices. This promotes easier stocking, consistent wiring conventions, and straightforward retrofits in existing installations, helping distributors and panel shops reduce engineering effort and accelerate project timelines.
