Eaton EBR-Z-2B1 Bus differential relay - High Z Module
Part Number: EBR-Z-2B1
Quick Summary
The Eaton EBR-Z-2B1 Bus differential relay is a fast feeder protection device designed for electrical distribution systems. In field deployments, nuisance trips and slower fault isolation can erode uptime and inflate maintenance costs. Compliance notes: Specific certifications such as SIL, CE and IP ratings are typically determined by the project; verify with Eaton for this model. With projection panel mounting and compatibility with the EBR-3000 base relay, it supports scalable protection schemes while delivering reliable operation and simplified installation. This combination gives engineers a clear path to meet protection coordination, asset uptime, and maintenance budgets. Relevant keywords include feeder protection, bus relay, and projection panel mounting.

Feature: High impedance module enables accurate differential protection with fast fault isolation. Benefit: Reduces nuisance trips and improves protection selectivity for feeders, which minimizes unnecessary outages in switchgear. Application: Ideal for feeder protection schemes in electrical distribution panels where precise fault discrimination matters. Feature: Robust energy handling with 10400 Joules rating. Benefit: Resilient under high-energy fault events, preserving switchgear integrity and reducing component wear. Application: Suitable for industrial power systems facing high-energy faults and long-duration transients. Feature: Projection panel mounting for easy field retrofit. Benefit: Speeds installation and simplifies maintenance, lowering labor costs and downtime. Application: Retrofit projects and new builds where space is constrained and quick install is valued. Feature: Compatibility with EBR-3000 base relay. Benefit: Streamlines integration into existing protection schemes, enabling scalable upgrades without redesign. Application: Modernization projects in switchgear where a unified protection platform is desired. Feature: Operational tolerance from -20°C to 60°C. Benefit: Reliable performance in harsh industrial environments, reducing temperature-related trips and downtime. Application: Outdoor or climate-variable facilities where ambient conditions vary. Warranty and service terms provide business value: a one-year warranty from installation (or eighteen months from shipment) helps manage risk and protect protection investments, supporting total cost of ownership objectives for automation and electrical protection projects.
