Eaton EBR-3Z-2B0KA1-A Bus differential relay - 61850
Part Number: EBR-3Z-2B0KA1-A
Quick Summary
The Eaton bus differential relay provides high-impedance protection for switchgear bus bars. It supports fast fault detection and isolation, helping prevent cascading faults in large power networks. Compliances are listed as 'Contact Manufacturer' in the data sheet, so certification specifics should be confirmed with Eaton; note that industry-standard protocols such as 61850, MODBUS, and DNP3 are supported for seamless SCADA integration. With projection-panel mounting and a compact common bezel, this relay offers practical installation in existing cabinets while enabling scalable protection schemes. The unit operates at 50/60 Hz with a 5 A contact rating and a manageable burden, enabling reliable protection without excessive power draw. Leveraging these features improves system reliability and reduces maintenance overhead in industrial environments.
