Eaton EBR-3Z-2B0LA0-A Bus differential relay - High Impedance
Part Number: EBR-3Z-2B0LA0-A
Quick Summary
The Eaton Bus differential relay is a high-impedance protection device designed to safeguard busbars in power distribution systems. For engineers tasked with rapid fault isolation, nuisance trips and integration challenges are common pains the EBR-3Z helps mitigate. Certification details vary by region; consult Eaton for current CE, SIL, and IP ratings and any jurisdictional approvals. The unit supports MODBUS/DNP3 communications and standard mounting, delivering reliable bus protection while enabling scalable SCADA integration. In business terms, it reduces downtime, supports modular upgrades with the EBR-Z High Impedance Module, and aligns with a 50/60 Hz electrical protection strategy across medium and large switchgear. This combination supports lifecycle cost reduction through fewer trips and easier maintenance.

FAQs
Install the relay on a compatible panel using the standard mounting method and common bezel. Plan for a 13.64 in width, 8.62 in height, and 7.49 in depth footprint, with the unit weighing 12.7 lb. Wire the 5 A contact rating and connect the MODBUS/DNP3 interface for control and monitoring. Verify clearance for heat dissipation and access for maintenance.
Key specs include 50/60 Hz operation, 5 A AC/DC contact rating, burden of 10 W / 17 VA, energy storage of 5.2 kJ, and operating temperature from -20°C to 60°C. The device is designed for robust bus differential protection in mid-to-large switchgear, enabling fast, selective tripping under fault conditions.
Yes, the EBR-3Z-2B0LA0-A includes MODBUS/DNP3 communications via a common bezel configuration. This enables remote monitoring, control, and data collection from SCADA systems, reducing on-site maintenance trips and providing real-time visibility for protection schemes across multiple feeders.
Compliances are designated as Contact Manufacturer, and Eaton provides region-specific certifications. For CE, SIL, and IP ratings, verify current approvals with Eaton to ensure alignment with your local regulatory requirements and installation environment before procurement.
The relay’s modular upgrade path (EBR-Z High Impedance Module), reliable 50/60 Hz protection, and scalable integration contribute to reduced downtime and easier maintenance. A one-year warranty (or 18 months from shipment) supports asset protection, while the 5 A contacts and 5.2 kJ energy rating help minimize downtime during fault events, improving total cost of ownership.
