Eaton EBR-3Z-2B0CA1-B Bus differential relay - Hi-Z
Part Number: EBR-3Z-2B0CA1-B
Quick Summary
Eaton Bus differential relay is a protective device used to detect faults in busbars and improve power system reliability. Engineers often struggle with coordinating protection schemes and avoiding nuisance trips during transient events. Compliance details vary by region, so verify CE/SIL/IP ratings with Eaton to ensure regulatory alignment. With Modbus/DNP3 communications and a projection-mount design, it supports scalable, cost-efficient protection in modern switchgear.

FAQs
Installers should use the projection panel mounting design to secure the relay in the enclosure. Utilize the common bezel with the EBR-Z High Impedance Module for future upgrades. Connect the MODBUS/DNP3 RJ45 interface for SCADA visibility, and verify the 7.49 in depth, 13.64 in width, and 8.62 in height fit within the panel layout.
The device operates at 50/60 Hz, with a 5 A AC/DC contact rating and a burden of 10 W / 17 VA. It supports a wide operating temperature range from -20°C to 60°C. The unit is designed for projection-panel mounting and integrates with standard control circuits.
Yes. The EBR-3Z-2B0CA1-B includes MODBUS/DNP3 (RJ45) communication capabilities, enabling remote monitoring, status checks, and protection coordination within a plant-wide SCADA environment. This supports faster response times and centralized asset management.
Compliance details vary by region. The product lists ‘Compliances: Contact Manufacturer,’ so confirm CE, SIL, IP ratings, and any regional approvals directly with Eaton before purchase or integration to meet local regulatory requirements.
ROI is driven by improved protection selectivity, reduced nuisance trips, and easier retrofits via the EBR-Z module. SCADA integration via MODBUS/DNP3 provides better visibility and predictive maintenance, while the compact projection-mount design lowers installation time and labor costs.
