Eaton EBR-3Z-2B0CA0-A Bus differential relay - High Z
Part Number: EBR-3Z-2B0CA0-A
Quick Summary
Eaton Bus differential relay provides fast fault isolation for bus protection in switchgear. When protection coordination fails or trips lag, outages can escalate into costly downtime and equipment damage. Certification details are not readily listed in the data; consult Eaton for verified CE, UL, IP ratings and regional approvals. With MODBUS/DNP3 (RJ45) communication, standard mounting, and a 50/60 Hz design, this relay is ready for scalable protection in modern distribution systems, while the 5 A contact rating and 10 W / 17 VA burden support reliable signaling without overloading circuits. This combination translates to quicker fault clearance, reduced maintenance, and easier integration into new or retrofit installations.

FAQs
Installers should plan for standard mounting on compatible panels and space for the 13.64 in width by 8.62 in height footprint. The unit communicates via RJ45 using MODBUS/DNP3 and weighs about 12.7 lb. Ensure operating temperature stays between -20°C and 60°C and verify panel wiring supports a 5 A signaling path with a 10 W / 17 VA burden.
Key specs include a 50/60 Hz frequency rating, 5 A contact rating for AC/DC signaling, and a burden of 10 W / 17 VA. These parameters support reliable differential protection signaling without overloading the protection circuit, while ensuring compatibility with standard protection schemes in modern substations.
Yes. The EBR-3Z-2B0CA0-A is designed for high impedance bus differential protection and pairs with the EBR-Z High Impedance Module, enabling robust differential protection in medium to large switchgear assemblies and retrofits.
Certification details are not listed in the shared data; contact Eaton for verified CE, UL, IP ratings, and regional approvals. This ensures the device complies with your local electrical standards before a procurement decision.
The relay offers a one-year warranty from installation (or 18 months from shipment) and streamlined installation with standard mounting, reducing commissioning time. Its modular approach, RJ45 communications, and reliable differential protection translate into lower maintenance costs and faster recovery after faults.
