Eaton EBR-3Z-2B0EA1-B Bus differential relay - Profibus-DP
Part Number: EBR-3Z-2B0EA1-B
Quick Summary
Bus differential relay from Eaton protects feeders in industrial power systems with fast, differential current detection. Engineers often face downtime and miscoordination when protection relays don’t integrate cleanly with PLC networks. This model supports 40-250 Vac and 19-300 Vdc supplies and offers Profibus-DP communication, with 8 digital inputs and 6 outputs for flexible control. Compliance specifics vary by region, so verify with the manufacturer for applicable CE/SIL/IP markings and documentation. Ideal for feeder protection in production lines and data centers alike, it reduces commissioning risk and improves maintenance workflows through a proven base relay (EBR-3000) and a panel-friendly form factor.

Wide power supply range and projection-panel mounting enable a single device to cover multiple regional mains and retrofit scenarios, reducing spare parts and accelerating installation; this translates to lower upfront costs and faster time-to-protect feeders in new builds or upgrades. The eight digital inputs, six digital outputs, and one current sensing input provide comprehensive local monitoring and interlocking capability, delivering precise protection decisions while minimizing external wiring and integration complexity. Profibus-DP (RS485 / D-SUB interface) ensures seamless PLC/SCADA communication and data logging, which improves fault analytics, troubleshooting speed, and network reliability in automated plants. The unit’s base compatibility with EBR-3000 allows scalable protection architecture, simplifying future expansions and maintenance planning while keeping panel space efficient. Projection-panel mounting and removable terminals support easy field installation and quick maintenance access, reducing downtime during battery checks or relay swaps. Operating from -20° to 60°C and a 5 A contact rating supports robust performance in typical industrial environments, with a manageable power burden of 10 W / 17 VA.

FAQs
How do I mount the Eaton EBR-3Z-2B0EA1-B and wire it for a standard feeder protection job? This relay uses projection-panel mounting with removable terminals for quick field wiring. It supports a base EBR-3000, 8 digital inputs, 6 outputs, and a 40-250 Vac / 19-300 Vdc power range. Plan your panel layout to minimize wire runs and allow easy access for maintenance.
The device monitors current differences between feeder conductors to detect faults and isolate them rapidly. It provides 5 A contact rating, 50/60 Hz operation, and a broad power supply window (40-250 Vac, 19-300 Vdc). With 8 inputs and 6 outputs, it supports robust interlocking and status signaling, reducing nuisance trips and improving system uptime.
Yes, the relay offers Profibus-DP via RS485 / D-SUB interface, facilitating integration with PLCs and automation networks. This enables seamless data exchange, remote monitoring, and centralized protection logic, which helps shorten fault diagnosis times and streamline commissioning in assembly lines and process facilities.
Compliance details are listed as 'Contact Manufacturer' for this product, so verify region-specific certifications with Eaton. In practice, confirm CE, SIL, IP ratings, or other local approvals required for your installation, and request documentation and test reports to ensure regulatory alignment and safe operation within your environment.
The Eaton EBR-3Z-2B0EA1-B carries a one-year warranty from installation or an 18-month window from shipment, whichever comes first. For maintenance, rely on the EBR-3000 base platform and modular design to simplify replacements and upgrades, reducing downtime and preserving system protection without replacing the entire assembly.
