Eaton Specification Sheet - ER54016UX
Feature → Business Impact → Application: The ER54016UX is a four-pole enclosed rotary disconnect with a non-fusible design that ensures safe, deliberate de-energization of motor circuits. This enhances personnel safety and reduces the risk of arc flash during maintenance, which translates to safer plant operations and improved compliance in electrical safety programs. In practice, it supports machine control cabinets and panel installations where reliable isolation is essential for servicing and startup sequences. Feature → Business Impact → Application: The NEMA 4X enclosure is non-metallic and weather-resistant, delivering protection in both indoor and exposed environments. This reduces enclosure corrosion and maintenance costs while extending service life in harsh locations, such as wash-down areas or dusty production lines. It is well-suited for food & beverage, chemical processing, and outdoor machinery control panels. Feature → Business Impact → Application: With 600 V voltage rating and HP ratings up to 10 hp at 208–600 V, the ER54016UX provides broad motor compatibility for typical industrial drives and equipment, improving installation flexibility and reducing part variety. It streamlines procurement for multiple line applications, including conveyors and packaging systems. Feature → Business Impact → Application: UL Listed and CSA Certified compliance assures customers and inspectors of meeting recognized safety and performance standards, simplifying audits and helping procurement teams justify the purchase as a compliant power-switching device. Feature → Business Impact → Application: The compact 10.4 in x 6.7 in x 7.8 in footprint and 5.5 lb weight enable easy mounting in compact control panels or retrofit projects, improving enclosure utilization and easing field installation for retrofits in aging systems. This is especially beneficial for OEMs integrating new control logic with existing mechanicals. Warranty and support from Eaton further reduce risk by providing standard coverage and access to spec sheets and documentation for installation and maintenance planning.
