Eaton Specification Sheet - ER54016UG
16 A amperage rating along with HP ratings of 3/5/10/10 hp (@208/240/480/600 V) ensures the ER54016UG can safely disconnect common motor loads. This alignment reduces overdesign, minimizes wiring complexity, and supports compact control schemes in conveyors and fans. The 600 V voltage rating and four-pole design guarantee complete isolation of all poles, preventing backfeed during maintenance and simplifying code compliance for motor circuits in metalworking and processing lines. The NEMA 1 painted steel enclosure offers indoor protection against dust and incidental contact, reducing enclosure corrosion risk and extending service life in typical workshop environments. Being part of Eaton’s R-Series, the unit offers standardization, faster procurement, and straightforward replacement in retrofit projects. CSA Certification and UL Listing reinforce safety compliance, lowering qualification time for projects in regulated environments while delivering predictable performance for downstream automation.
