Eaton EBR-3000-2B0KB0 Bus differential relay - 61850/MODBUS/DNP3
Part Number: EBR-3000-2B0KB0
Quick Summary
Eaton Bus differential relay protects busbars and feeders by detecting high-impedance faults in power networks. Engineers often face nuisance trips and slow fault localization when protection schemes aren’t tightly coordinated. While formal SIL, CE, or IP ratings aren’t published in this listing, the device uses conformal coating for harsh industrial environments and supports IEC 61850, Modbus, and DNP3 for seamless SCADA integration. These features deliver improved reliability and interoperability, helping you reduce downtime, shorten maintenance windows, and meet modern protection-stack requirements. Even in dense utility and plant networks, the solution scales with your protection strategy.

FAQs
The relay uses standard mounting suitable for typical panel or enclosure installations. Its dimensions are 7.49 inches in depth, 8.62 inches in height, and 6.82 inches in width, with a weight of 5.3 pounds. For optimal fit and performance, verify panel cutouts and ensure adequate ventilation and wiring clearance per Eaton’s installation guidelines. Consider the optional EBR-Z High Impedance Module to enable full high-impedance protection when planning system upgrades.
Key specs include a 50/60 Hz frequency rating, 5 A contact rating (AC/DC), and a burden of 10 W / 17 VA. These parameters influence CT sizing, relay coordination, and overall protection selectivity. The unit is configured for high-impedance differential protection in bus applications, which helps minimize nuisance trips while preserving fast fault clearance under fault conditions.
Yes. The EBR-3000-2B0KB0 is designed for bus differential protection, with options to integrate IEC 61850, Modbus, and DNP3 communications for SCADA. For full high-impedance functionality, pairing with the EBR-Z Module is recommended. Its conformal coating and wide operating temperature range support reliable operation in diverse environments typical of substations and industrial plants.
This listing notes Compliances as 'Contact Manufacturer.' While formal SIL, CE, or IP ratings aren’t published here, Eaton provides rugged devices with conformal coating and widely supported communication protocols (IEC 61850, Modbus, DNP3). Prospective buyers should confirm any regulatory certifications directly with Eaton prior to purchase to ensure alignment with project requirements.
ROI benefits come from faster, more reliable fault isolation, reduced outage times, and improved protection coordination across bus and feeder networks. The device’s compact footprint, standard mounting, and compatibility with SCADA protocols enable quicker deployment and easier maintenance. Additionally, the option to upgrade with the EBR-Z module provides a scalable path as protection requirements evolve.
