Eaton EBR-3Z-2B0BA1-A Bus differential relay - 5 A
Part Number: EBR-3Z-2B0BA1-A
Quick Summary
The Eaton Bus differential relay is a protection device that detects feeder faults and isolates them to prevent outages. Field engineers often face nuisance trips and limited fault visibility; the EBR-3Z-2B0BA1-A provides integrated Modbus RTU and DNP3.0 RTU communications to streamline supervision. Compliance details are handled by the manufacturer; regional requirements such as CE, IP ratings, and SIL applicability should be verified with Eaton to ensure site acceptance. With a wide power range and projection panel mounting, this relay fits modern panel builds and supports scalable feeder protection strategies across 40-250 Vac and 19-300 Vdc systems, while maintaining reliable operation in -20° to 60°C environments.

FAQs
The relay uses a projection panel mounting method with removable terminals, simplifying installation and future maintenance. Ensure space for 13.64 in width, 8.62 in height, and 7.49 in depth, and plan for RS485 wiring to support Modbus RTU + DNP3.0 RTU communications. Pre-wire the 8 digital inputs and 6 outputs to align with your feeder protection scheme. Confirm terminal access facilitates quick field testing after commissioning.
Key specs include a 40-250 Vac / 19-300 Vdc power range, 50/60 Hz operation, 5 A contact rating, and a burden of 10 W / 17 VA. The device supports one current-sensing input, eight digital inputs, and six digital outputs, enabling robust protection logic and signaling within standard distribution panels.
Yes, it is designed for industrial environments with an operating range from -20°C to 60°C. The projection panel mount and removable terminals facilitate rugged installations, while the 5 A contact rating supports reliable switch control. For outdoor or harsh locations, verify enclosure protection and regional compliance specifics with Eaton before deployment.
Compliances are listed as 'Contact Manufacturer' in the product data, so you should confirm regional requirements directly with Eaton. Ask about CE marking, IP ratings, and SIL applicability if your safety and reliability standards require them. Ensure your site’s regulatory framework aligns with the manufacturer’s documented certifications and installation guidelines.
The relay consolidates protection, signaling, and monitoring in a single device, reducing hardware counts (no extra relays needed for signaling). With integrated Modbus RTU + DNP3.0 RTU and remote monitoring capabilities, maintenance intervals can be extended and fault diagnostics accelerated, translating to lower downtime costs and improved feeder availability.
