Eaton EBR-3Z-2B0BA0-B Bus differential relay - Modbus RTU

Power supply range and voltage flexibility: The device operates from 19-300 Vdc or 40-250 Vac, eliminating the need for multiple supply rails and simplifying cabinet wiring. In practice this reduces installation time and stocking costs while expanding compatibility across feeders that mix AC and DC sources. It’s ideal for industrial plants, data centers, and utility feeders where supply conditions vary. I/O capabilities with status signaling and local control: 8 digital inputs, 6 digital outputs, and 1 current sensing input enable precise feeder coordination and robust local control. This reduces external wiring and accelerates fault-response workflows, making it well-suited for automated distribution schemes and interlocking in complex panel layouts. Communication for modern plants: Modbus RTU + DNP3.0 RTU (RS485) provides seamless SCADA integration and remote diagnostics. Operators gain centralized visibility and faster fault isolation, helping to meet uptime commitments in manufacturing and data centers. Low power burden and efficiency: With a burden of 10 W / 17 VA, the relay minimizes heat in switchgear cabinets and supports energy-conscious design practices in large assemblies and underground or space-constrained installations. Rugged installation and adaptability: -20° to 60°C operation, standard mounting, and removable terminals simplify field wiring and cabinet integration. This enables quick upgrades in retrofit projects and reliable performance in harsh environments. Protection features and compatibility: The unit plugs into the EBR-3000 base relay with 5 A contact rating, 50/60 Hz compatibility, and a complete set of digital I/O for feeder protection applications, delivering a scalable solution for growing automation needs.
