Eaton EBR-3000-2B0EA1 Bus differential relay - Profibus-DP
Part Number: EBR-3000-2B0EA1
Quick Summary
The Eaton Bus differential relay protects feeders by quickly detecting faults and isolating them, preventing cascading faults in complex power systems. This capability reduces outage duration, limits equipment damage, and helps technicians avoid prolonged fault tracing that slows commissioning. Typical protection platforms align with CE safety requirements, SIL-ready logic for safety-critical circuits, and IP-rated enclosures suitable for harsh environments. The EBR-3000-2B0EA1 supports a flexible power supply range of 19-300 VDC or 40-250 VAC, eight digital inputs, six outputs, and a Profibus-DP RS485 interface, enabling scalable control and rapid diagnostics. Its projection panel mounting and removable terminals simplify installation and service, delivering lower lifecycle costs and improved system reliability.
