Eaton Generator Relay EGR-5000-2A0LB1 - 50/60 Hz
Part Number: EGR-5000-2A0LB1
Quick Summary
Eaton generator relay is a protective device for generator sets, enabling fast protection and reliable monitoring in industrial power systems. Engineers often struggle with complex protection schemes, integration with SCADA, and coordinating start/stop signals during outages. While this relay delivers robust functionality, users should verify compliance details with Eaton to ensure site-specific certifications. Its broad voltage sensing (19–300 Vdc, 40–250 Vac) and 50/60 Hz operation support both new builds and retrofit projects, while M-Bus TCP or DNP3 TCP/UDP interfaces streamline remote monitoring. In addition, the unit's 16 digital inputs, 9 outputs, and 2 current sensing inputs provide flexible protection logic and metering, helping manufacturers, utilities, and data centers reduce downtime and optimize maintenance.

16 digital inputs and 9 programmable outputs enable complex interlocks and remote signaling. The business impact is faster fault isolation and more precise trip coordination, reducing outage duration in large generator banks and critical facilities. This configuration supports generator protection schemes across industrial plants and data centers. Two current sensing inputs and 5A/1A current transducers improve protection accuracy and metering. The business impact is reliable overcurrent and differential protection with clear event logging, enabling faster outages analysis. Applications include multi-generator sets or islanded microgrids where accurate fault detection matters. Power supply range of 19-300 Vdc and 40-250 Vac allows use from DC control buses to AC power rails. The business impact is easier integration with existing plant electrical systems and reduced wiring complexity. It’s especially beneficial for retrofit projects where new relays must plug into legacy controls. M-Bus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet enables remote monitoring and SCADA integration. The business impact is centralized visibility, faster diagnostics, and proactive maintenance. This supports critical facilities like hospitals, data centers, and manufacturing lines that demand uptime. I/O options such as URTD Interface, Trip Coil Monitor, and IRIG-B ensure precise trip signaling and time stamping. The business impact is improved testing, audit trails, and alignment with protection coordination study results. Coupled with removable terminals and projection mounting, installation and field service are streamlined. Conformal coating increases reliability in harsh environments; removable terminals and projection mounting simplify field swaps.

FAQs
Installation should begin with a careful assessment of your generator configuration to determine which digital inputs and outputs will be wired for protection zones. The device features removable terminals and projection mounting for straightforward mounting in control cabinets or on equipment racks. Use the 19–300 Vdc or 40–250 Vac power feeds to match your plant electrical system, and integrate M-Bus TCP or DNP3 TCP/UDP for SCADA communications to ensure proper fault reporting and remote monitoring.
Key specs include 16 digital inputs, 9 outputs, 2 current sensing inputs, and 5A/1A phase current sensing options. The unit supports 50/60 Hz operation and wide voltage sensing ranges (19–300 Vdc, 40–250 Vac), enabling precise protection coordinates, metering, and fast trip decisions essential for generator banks and critical applications.
Yes. The EGR-5000-2A0LB1 is designed for generator protection in mission-critical environments. Its Timed signaling options, IRIG-B time stamping, and SCADA-compatible communication (M-Bus TCP/DNP3 TCP/UDP) support stringent uptime requirements, auditing, and coordinated protection across multiple generators.
Compliance details are provided by the manufacturer. The product listing indicates ‘Compliances: Contact Manufacturer,’ so verify site-specific standards (CE/SIL/IP as applicable) directly with Eaton before deployment in regulated environments and ensure alignment with your facility’s protection coordination studies.
ROI is driven by reduced downtime, faster fault isolation, and better protection coordination. The relay’s remote monitoring via M-Bus/DNP3 and its flexible I/O simplify maintenance scheduling, while robust field installation features lower labor costs during retrofits and upgrades, delivering measurable reliability and efficiency gains.
