Eaton EBR-3000-2B0CB0 Bus differential relay - Requires EBR-Z High Impedance Module
Part Number: EBR-3000-2B0CB0
Quick Summary
The Eaton Bus differential relay EBR-3000-2B0CB0 delivers high-impedance differential protection for switchgear applications. Engineers often confront nuisance trips and complex configuration when protecting feeders; this device simplifies setup, improves selectivity, and minimizes outages. While performance hinges on robust communication and environmental resilience, key capabilities include 50/60 Hz operation, conformal coating, and an easy RJ45 MODBUS/DNP3 interface, with compatibility to the EBR-Z High Impedance Module. Note that certification specifics such as CE or SIL depend on regional approvals and must be confirmed with Eaton. By combining reliable protection with straightforward installation, this relay supports reduced maintenance costs and improved system uptime for industrial power networks.
