Eaton EBR-3Z-2B0TA0-A Bus differential relay - 5.2kJ
Part Number: EBR-3Z-2B0TA0-A
Quick Summary
The Eaton bus differential relay protects medium-scale bus systems by detecting differential faults across busbars. Inconsistent protection can cause costly outages and equipment damage during transient events. Certification details (CE, IP ratings, SIL) aren’t listed here; confirm with the manufacturer for your compliance needs. With 61850, MDBS, and DNP3 communications over RS485 RJ45, plus a standard mount and 5 A contact rating, it fits modern automation workflows. This translates to faster fault isolation, reduced maintenance costs, and smoother integration with protection schemes. Engineers benefit from verified performance within Eaton's protection ecosystem.

FAQs
Install the EBR-3Z-2B0TA0-A using the standard mounting method, ensuring clearance for its 7.49 in depth and 13.64 in width. Verify RS485 RJ45 connectors and 61850/MDBS/DNP3 communication lines are correctly terminated. Check the bus differential wiring against the manufacturer’s datasheet, and confirm ambient temperature suitability (-20° to 60°C) for reliable operation.
Key specs include a 50/60 Hz frequency rating, 5 A contact rating (AC/DC), burden of 10 W / 17 VA, and a weight of 12.7 lb. The unit is designed for standard mounting, with a high-impedance bus differential protection scheme suitable for common-bezel configurations.
Yes. The relay supports 61850, MDBS, and DNP3 communications via RS485 RJ45, enabling integration with modern substation automation and protection systems while reducing wiring complexity and improving data exchange with protection schemes.
The device operates from -20°C to 60°C, making it suitable for both indoor and rugged industrial environments. Ensure the installation location provides adequate ventilation and avoids exposure to conditions outside this range to maintain reliability.
Warranty is Eaton’s standard policy: one year from installation or 18 months from shipment, whichever comes first. Compliance details are listed as 'Contact Manufacturer'—verify specific certifications with Eaton to ensure alignment with your project’s regulatory requirements.
