Eaton EGR-5000-2B0GB1 Generator Relay - RS-485
Part Number: EGR-5000-2B0GB1
Quick Summary
The Eaton generator relay protects generator sets by monitoring voltage, current, and phase conditions to trigger timely protective actions. This helps prevent unscheduled outages and costly equipment damage in critical facilities. Compliance details vary by region, and formal approvals should be confirmed with Eaton. Designed for generator protection, the EGR-5000-2B0GB1 offers Modbus RTU or DNP3 RTU communication over RS-485, plus flexible input/output, and a rugged, conformal-coated design. With projection mounting and removable terminals, it simplifies installation and enables reliable integration with modern automation systems across industrial, data-center, and utility applications.

FAQs
Install with projection mounting and removable terminals for straightforward mounting. Connect the RS-485 Modbus or DNP3 RTU wiring, map the 8 inputs and 9 outputs to your control logic, and configure sensing channels (voltage, current, and power metering) to align with your protective scheme. This minimizes downtime and simplifies future upgrades.
The relay supports Modbus RTU or DNP3 RTU over RS-485 via a D-Sub interface. This enables seamless integration with common SCADA, EMS, and protection schemes, reducing integration time and enabling centralized monitoring of generator health and protection events.
Yes. It is rated for 50/60 Hz operation and accepts a dual power supply range of 19-300 VDC or 40-250 VAC, making it compatible with diverse genset configurations and electrical environments without requiring extensive power conversion hardware.
The EGR-5000-2B0GB1 provides voltage protection and metering, current protection and metering, power protection and metering, and differential protection. With Zone Selective Interlocking, it enhances protection coordination, reducing the risk of widespread outages during faults.
Warranty is one year from installation or 18 months from shipment, whichever occurs first. For detailed certification status and regional approvals, contact Eaton support to confirm current compliance documentation and any region-specific requirements.
