Eaton Generator Relay EGR-5000-2A1KA0 - 50/60 Hz
Part Number: EGR-5000-2A1KA0
Quick Summary
The Eaton generator relay is a robust protection device that safeguards generators and ensures reliable operation in critical power systems. In practice, engineers often face nuisance trips, miscoordination, and extended downtime when protection schemes aren’t aligned with generator dynamics. This model supports differential protection, trip coil monitoring, and a sensitive ground input, with an IRIG-B interface and zone selective interlocking for precise, coordinated protection. By delivering flexible I/O, wide supply ranges, and proven Eaton engineering, it helps improve site reliability, reduce unplanned outages, and simplify integration with existing control architectures in industrial and utility environments.
