Eaton EBR-3Z-2B0LB0-A Bus differential relay - 5.2kJ
Part Number: EBR-3Z-2B0LB0-A
Quick Summary
Eaton Bus differential relay delivers high impedance protection for switchgear bus sections, enabling reliable fault isolation in distribution systems. Engineers often struggle with nuisance trips and miscoordination when using traditional low-impedance schemes, which can cause outages and costly downtime. This model emphasizes robust protection with common bezel compatibility and advanced communications, while ensuring field reliability through conformal coating and standard mounting. Designed for 50/60 Hz operation, it supports MODBUS and DNP3 networks, making integration with SCADA and energy management systems straightforward. By reducing false trips and improving protection selectivity, it delivers measurable business value for reliability-led maintenance programs and long-term asset health.
