Eaton generator relay EGR-5000-2A0BA1 - RS-485 Modbus/DNP3
Part Number: EGR-5000-2A0BA1
Quick Summary
Eaton generator relay protects generators by monitoring faults and triggering auto-start/stop in power systems. Engineers and procurement teams often struggle with miscoordination, nuisance trips, and downtime during generator transitions, making protection timing critical. Regional compliance may include CE marking and UL listings, plus IP-rated enclosures for rugged environments. This model supports RS-485 Modbus RTU and DNP3 RTU for seamless PLC integration, alongside differential, voltage, and current protection metering for precise coordination. With broad I/O, a robust protection suite, and practical installation options, it delivers measurable value by reducing mis-trips and accelerating fault isolation while simplifying field wiring and commissioning.
