Eaton EBR-3000-2B0TA1 Bus Diff Relay - High Impedance
Part Number: EBR-3000-2B0TA1
Quick Summary
Eaton EBR-3000-2B0TA1 bus differential relay protects power buses in switchgear and substations. Engineers struggle with nuisance trips and slow fault isolation during bus faults. This device supports 61850, MDBS, and DNP3 over RS-485 RJ45 and uses a projection-panel mount for easy integration. Note that CE, SIL, and IP certifications should be confirmed with the manufacturer, as the data lists only 'Compliances: Contact Manufacturer.' The result is improved system reliability and faster fault clearance, reducing downtime and maintenance costs for ongoing protection schemes. This solution aligns with industrial protection relay requirements and supports scalable, field-proven protection strategies.

High Impedance protection with optimized selectivity → Reduces nuisance trips and improves fault isolation, delivering measurable uptime gains in large switchgear and substations. This is particularly valuable for utilities and data centers seeking reliable bus protection and lower maintenance costs. Projection panel mounting → Simplified installation, reduced field wiring, and better cabinet integration, enabling faster commissioning and more predictable performance in industrial environments. 61850, MDBS, DNP3 over RS485 RJ45 → Seamless integration with modern digital substations and SCADA systems, supporting remote diagnostics and accelerated fault analytics. Contact rating of 5 A AC/DC and a 50/60 Hz electrical footprint → Flexible interface options for alarm and trip circuits with broad compatibility across standard control architectures. Burden 10 W / 17 VA → Favorable power budget for protection schemes operating within tight electrical budgets. Operating temperature range -20° to 60°C → Reliable operation in harsh plant environments, minimizing the risk of performance degradation. Warranty terms (Eaton Selling Policy 25-000) → Short-term risk protection and a clear framework for service, aiding total cost of ownership calculations. This combination of protection accuracy, installation efficiency, and protocol compatibility makes the EBR-3000-2B0TA1 a robust choice for power-bus protection in industrial plants, substations, and critical infrastructure, while supporting scalable protection schemes and remote monitoring.

FAQs
Begin with confirming panel space and mounting provisions for a projection-panel relay. Install the chassis, secure the front panel, and route RS485 RJ45 wiring to the host 61850/MDBS/DNP3 network. Connect the 5 A AC/DC contacts as required for alarms or trips, observe proper creepage distances, and verify the 50/60 Hz power source compatibility. Finally, perform fabricante-recommended parametrization and a functional test to validate protective operation.
Yes. The EBR-3000-2B0TA1 supports 61850 and DNP3 communications via MDBS over RS485 RJ45. This enables interoperability with modern substation automation systems and allows for remote monitoring, event reporting, and centralized protection coordination within an industrial network.
Its high-impedance differential design provides selective fault detection on the protected bus, reducing misoperation risk during CT saturation or external disturbances. The RS485 interface with 61850/MDBS/DNP3 supports scalable networking, while projection mounting enables compact, vibration-resistant installations in demanding environments common to utilities and data centers.
Critical certifications such as CE, SIL, and IP ratings should be verified with the manufacturer, as the current data lists Compliances as 'Contact Manufacturer.' Before deployment, confirm applicable regulatory approvals, environmental ratings, and any site-specific standards to ensure full compliance and safe operation in your facility.
The unit carries Eaton’s warranty policy (25-000) with a one-year from installation or eighteen months from shipment window. Plan for periodic relay diagnostics, contact check, and enclosure inspection to maintain performance. The device’s robust operating range (-20°C to 60°C) supports long-term reliability in harsh environments, while remote monitoring capabilities aid proactive maintenance and quick fault diagnosis.
