Eaton EBR-3Z-2B0LB1-A Bus Differential Relay - 5.2kJ
Part Number: EBR-3Z-2B0LB1-A
Quick Summary
Eaton Bus differential relay protects medium and large electrical feeders by delivering fast differential fault detection. Coordinating protection settings across panels can lead to nuisance trips and unplanned downtime when interfaces and modules don’t align. Formal certifications such as CE, SIL, or IP ratings are not listed in this datasheet; please contact Eaton for current approvals and status. With MODBUS/DNP3 (FO LC), conformal coating, and projection-panel mounting, this unit enables seamless SCADA integration and rugged field performance, delivering reliability and reduced maintenance costs. Designed to withstand -20° to 60°C environments, it supports 50/60 Hz operation for global applications.

50/60 Hz operation and a 5 A contact rating are aligned with typical feeder protection schemes, delivering reliable sensing and control. This supports scalable protection for medium-to-large feeders, reducing nuisance trips in everyday operation. The device delivers 3000 High Impedance protection and a 5.2 kJ energy capacity, enabling fast, selective clearing while minimizing miscoordination across complex bus arrangements. MODBUS/DNP3 (FO LC) communications enable straightforward SCADA integration, improving visibility and control without adding wiring complexity. Conformal coating and rugged enclosure ensure reliable performance in harsh industrial environments, while projection-panel mounting simplifies installation and serviceability. The unit’s weight and dimensions (7.49 in deep, 8.62 in high, 13.64 in wide, 12.7 lb) support practical handling in crowded switchgear rooms. Its 10 W / 17 VA burden preserves feeder capacity and reduces overall system losses. Compatibility with the EBR-Z High Impedance Module in a common bezel provides modular scalability for future protection upgrades. The Eaton one-year warranty (or 18 months from shipment) helps protect your investment. This combination addresses common objections about integration time and maintenance costs with proven, field-ready reliability.
