Eaton EBR-3Z-2B0HA1-B Bus differential relay - 61850
Part Number: EBR-3Z-2B0HA1-B
Quick Summary
Eaton Bus differential relay protects feeder networks by high-impedance fault detection in electrical switchgear. This approach reduces nuisance trips and improves fault visibility during peak loading, helping maintenance teams avoid unexpected outages. Note: data lists Compliances as 'Contact Manufacturer' rather than specific certifications like CE, SIL, or IP ratings, so validate for your regional compliance; 61850/MODBUS/DNP3 communications and projection-panel mounting are clearly supported. These capabilities translate to faster repairs, safer coordination, and lower total cost of ownership while enabling seamless integration with modern protection schemes and remote monitoring.

Feature → Business Impact → Application: The high-impedance bus differential protection detects internal faults without triggering trips for external disturbances, reducing unnecessary outages and extending equipment life in medium-voltage switchgear deployments. This translates to improved system reliability, lower downtime costs, and clearer fault demarcation during high-load conditions in industrial plants. Application-wise, it is well-suited for feeder protection in substations and complex campus electrical networks where precision coordination matters. Feature → Business Impact → Application: The common bezel with projection-panel mounting simplifies retrofits and new installations, accelerating commissioning and minimizing cabinet rework. Quick alignment with existing gear reduces installation time and spare-part inventory, making it ideal for upgrade projects and space-constrained panel designs. Feature → Business Impact → Application: RJ45 communications supporting 61850, MODBUS, and DNP3 enables seamless integration with SCADA, protection relays, and remote monitoring. Operators gain real-time visibility, smarter alarm routing, and easier trend analysis across distributed energy resources. Feature → Business Impact → Application: A burden of 10 W / 17 VA and a robust 50/60 Hz electrical profile ensure stable operation with predictable thermal performance, lowering cooling requirements and boosting overall efficiency in control rooms and switchgear rooms. Feature → Business Impact → Application: The compact dimensions (7.49 in x 8.62 in x 13.64 in) and 12.7 lb weight support straightforward cabinet placement and modular integration, reducing space planning time and enabling scalable protection schemes in multi-bay configurations.
