FAQs
The EGR-5000-2A0GA0 supports Modbus RTU and DNP3 RTU over RS-485, enabling straightforward integration with PLCs, SCADA, and EMS. Its 16 digital inputs, 9 outputs, and two current-sensing inputs provide ample I/O for coordinated protection, annunciation, and control. This compatibility reduces commissioning time and simplifies the architecture for multi-generator plants.
The relay operates on a power range of 19-300 Vdc and 40-250 Vac with a 50/60 Hz rating. It features two current-sensing inputs, a single voltage-sensing input, and 16 digital inputs with 9 digital outputs. Sensing and protection cover differential, current, voltage, and power metering so you can tailor protection to your generator and system topology.
This generator protection relay is ideal for industrial environments such as manufacturing plants, data centers, and utility-backed facilities with multiple generators. Its zone selective interlocking enables coordinated protection across parallel units, while Modbus/DNP3 communication supports centralized monitoring and alarms. It’s well-suited for retrofit projects where existing control networks must be retained.
Compliances are region-specific and listed as 'Contact Manufacturer' in the data. For global deployments, verify CE marking for Europe, UL/CSA recognition for North America, and appropriate IP enclosure ratings. Eaton’s documentation and regional representatives can confirm the exact certifications applicable to your installation, ensuring safe and compliant integration.
With removable terminals and semi-flush mounting, installation and field wiring are streamlined, reducing commissioning time. The device integrates multiple protection functions and metering in a single relay, lowering panel costs and inventory. Zone selective interlocking minimizes unnecessary trips, improving generator availability and reducing unplanned downtime across critical facilities.
