Eaton EBR-3Z-2B0FA0-B Bus diff relay - High Impedance
Part Number: EBR-3Z-2B0FA0-B
Quick Summary
Eaton Bus differential relay protects busbars in industrial power systems by delivering fast, high-impedance fault isolation. This reduces nuisance trips and speeds fault clearance, helping keep critical processes online. In practice, you’re often balancing protection with selectivity; this unit provides precise coordination with standard mounting and a common bezel, simplifying retrofits in existing switchgear. Compliance considerations matter; verify with Eaton for regional CE, SIL, and IP ratings relevant to your installation. With 50/60 Hz operation and MODBUS/DNP3 (FO ST) communication, it integrates seamlessly with modern SCADA and protection schemes, supporting reliable control-room visibility and remote diagnostics. The result is improved uptime, easier maintenance planning, and lower total cost of ownership across distributed power networks.
