Eaton EBR-Z-2A0 Bus Differential Relay - High Impedance
Part Number: EBR-Z-2A0
Quick Summary
The Eaton bus differential relay is designed to protect feeder networks by detecting abnormal current differentials. In rugged industrial environments, protection schemes must trip quickly without nuisance activations. Certifications such as CE, IP ratings, and SIL vary by region; confirm current approvals with the manufacturer to ensure regional compliance. This module supports reliable, coordinated protection across distributed electrical systems. By pairing precise differential sensing with a standard mounting footprint, it reduces installation complexity and enables faster commissioning. For procurement teams, the solution offers predictable performance, straightforward spare-part compatibility, and a clear path to scalable feeder protection in growing facilities.

High Impedance Module compatibility with the EBR-3000 base relay enables precise differential protection in feeder configurations, improving fault isolation and reducing nuisance trips in busy industrial plants. Business impact: minimizes downtime and extends equipment life through coordinated protection, with straightforward integration into existing Eaton protection schemes. Application: suited for feeder protection in modern distribution networks where fast, accurate fault detection is critical. The energy handling capacity of 5200 Joules supports transient events without compromising protection accuracy, delivering dependable performance during faults. Business impact: enhances system resilience and reduces maintenance costs by tolerating surges that might otherwise trigger false alarms. Application: ideal for equipment with moderate to high transient loads and demanding industrial cycles. Operating temperature range of -20°C to 60°C ensures reliable operation in exposed environments, while a standard mounting method simplifies installation. Business impact: lowers installation time and on-site engineering effort. Application: common in retrofit projects and new builds where space is at a premium. Dimensions of 7.49 in L, 8.62 in H, 6.82 in W and weight of 7.4 lb provide a compact yet robust footprint. Business impact: enables easier enclosure planning and compatible spare parts management. Application: suitable for panelized protection schemes. Warranty of one year from installation or eighteen months from shipment helps control lifecycle costs and supports predictable ROI. Business impact: reduces risk of unexpected warranty gaps during field deployments. Application: aligns with standard Eaton policy for service continuity. Conformal coating is None and external communications are None, which informs enclosure and integration considerations for your specific environment. Application: plan your protective enclosure accordingly.

FAQs
The EBR-Z-2A0 is a High Impedance Module designed to be used with Eaton's EBR-3000 base relay. It uses the standard mounting approach and is intended for feeder protection applications, enabling coordinated differential protection when combined with the base unit.
The 5200 Joule energy rating defines the module's energy handling capacity to withstand transient surges without degrading sensing accuracy. This improves reliability during fault conditions and reduces the likelihood of nuisance trips that can disrupt production lines.
Yes, the module is rated for operation from -20°C to 60°C, supporting typical industrial environments. It ships with no conformal coating and no external communication, so consider enclosure protection and environmental controls to maintain optimal performance.
Plan for a footprint of 7.49 in (L) × 8.62 in (H) × 6.82 in (W) with a weight of 7.4 lb and Standard mounting. Ensure space within the enclosure for heat dissipation and wiring to the EBR-3000 base relay, and verify regional compliance requirements before field deployment.
The product carries a one-year warranty from installation or an 18-month warranty from shipment, whichever occurs first. ROI is driven by reduced downtime, faster fault isolation, and simplified spare parts management when integrated with Eaton protection schemes.
