Wide power supply and frequency range enables direct integration with diverse generator configurations, from 19-300Vdc to 40-250Vac and 50/60 Hz. This reduces the need for separate power conditioning, lowers installation costs, and speeds commissioning, making it ideal for standby and prime power in industrial plants and data centers. The dense I/O set—8 digital inputs, 9 digital outputs, 2 analog inputs, 2 analog outputs, plus 2 current sensing inputs—delivers versatile protection and metering. The result is precise fault detection, coordinated start/stop sequencing, and improved asset management, enabling fewer nuisance trips and better overall system reliability in complex genset deployments. Modbus/DNP3 RTU over RS-485 and an optional IRIG-B interface with Ethernet provide seamless SCADA integration and time synchronization, supporting centralized monitoring and fast fault diagnosis. Conformal coating on circuit boards and removable terminals simplify maintenance and retrofit work in dusty or corrosive environments, while semi-flush mounting streamlines installation. Zone selective interlocking is available to accelerate fault isolation and improve crew safety in multi-generator configurations, delivering measurable reductions in downtime and outage duration. Overall, the Eaton EGR-5000-2B0IB0 combines robust protection with flexible communication and installation advantages to meet the demands of modern industrial power systems.

FAQs
The EGR-5000-2B0IB0 accepts a power supply range of 19-300 Vdc or 40-250 Vac and supports 50/60 Hz operation, enabling direct connection to a wide range of genset configurations. Installation benefits include semi-flush mounting, removable terminals for easier wiring, and a conformal-coated circuit board for improved durability in harsh environments. Plan for RS-485 communication and optional Ethernet integration to support SCADA connectivity.
Yes. The EGR-5000-2B0IB0 supports Modbus and DNP3 RTU over RS-485, enabling seamless integration with existing SCADA systems. It also offers an Ethernet option for broader network access and IRIG-B interfaces for precise time synchronization, which helps coordinate protection actions across multiple devices in complex power systems.
The relay includes comprehensive protection features such as current protection and metering, voltage protection and metering, and differential protection. It also supports a Trip Coil Monitor and Zone Selective Interlocking for faster, safer fault isolation. With 8 digital inputs, 9 digital outputs, and 2 analog channels, it enables multi-parameter protection and accurate fault diagnosis.
Eaton provides a standard warranty under policy 25-000, typically covering one year from installation or eighteen months from shipment, whichever occurs first. For detailed coverage, service options, and firmware updates, consult with Eaton or the authorized distributor, ensuring you align support with your installation timeline and maintenance plan.
Yes, the EGR-5000-2B0IB0 includes Zone Selective Interlocking functionality. This enables selective tripping with coordinated protection logic, which reduces the impact of a single fault on non-faulted zones. In practice, this accelerates fault isolation, minimizes unnecessary outages, and improves overall availability of multi-generator configurations in critical facilities.
