Eaton EBR-3000-2B0FB0 Bus Differential Relay - High Impedance
Part Number: EBR-3000-2B0FB0
Quick Summary
The Eaton Bus differential relay EBR-3000-2B0FB0 protects electrical buses by detecting intra-bus faults in distribution networks. Engineers frequently struggle with nuisance trips and slow fault isolation, and this high-impedance device mitigates those issues by distinguishing internal faults from external disturbances. While exact certifications should be verified with Eaton, industry-standard measures such as SIL, CE, and IP ratings are commonly referenced on the datasheet for protection relays, and you should confirm the final ratings with the manufacturer. Together with the optional EBR-Z High Impedance Module and Modbus/DNP3 communications, this relay offers robust protection with straightforward integration for modern automation ecosystems, delivering reliability, faster restoration, and reduced operating costs.

FAQs
The device uses standard mounting and fits in typical control panels with dimensions of 7.49 in (L) x 8.62 in (H) x 6.82 in (W). It weighs 5.3 lb and has a burden of 10 W / 17 VA, making it suitable for compact, space-constrained panels. For best results, plan space for wiring to the 5 A contact rating and consider the optional EBR-Z High Impedance Module to extend protection. Verify clearance for cooling and conformal coating exposure in harsh environments.
Key specs include a 50/60 Hz frequency rating, -20°C to 60°C operating temperature, standard mounting, and a 5 A AC/DC contact rating. Burden is 10 W / 17 VA, ensuring manageable power consumption. The product supports conformal coating for environmental resilience and can operate within typical industrial electrical protection schemes without requiring custom interfaces.
Yes, the EBR-3000-2B0FB0 supports MODBUS/DNP3 (FO ST) communications, enabling straightforward SCADA integration and remote diagnostic capability. This compatibility reduces commissioning time and enhances real-time protection monitoring, which is critical for fast fault analysis and system restoration in automated facilities.
Compliances are listed as Contact Manufacturer on the product data; for mission-critical deployments, verify exact certifications (such as SIL, CE, IP ratings) with Eaton’s datasheet or regional representative. In practice, these relays are designed to meet typical industrial protection standards, but confirm the precise certifications required for your installation and regulatory environment.
The EBR-3000-2B0FB0 is covered under Eaton’s policy: one year from the date of installation or eighteen months from shipment, whichever occurs first. For retrofit projects, plan installation timing to maximize warranty benefits. Eaton also offers documentation, datasheets, and access to technical support for installation and integration questions, including compatibility with the EBR-Z module.
