Eaton EBR-3000-2B0KA1 Bus differential relay - High Z
Part Number: EBR-3000-2B0KA1
Quick Summary
Eaton Bus differential relay provides fast, high-impedance protection for busbars and feeders in electrical substations. When miscoordination or nuisance trips occur, traditional protections can cause unnecessary outages and downtime. In practice, robust protection strategies rely on industry certifications such as CE marking, IP enclosure ratings, and SIL safety considerations to meet field requirements. The EBR-3000-2B0KA1 integrates 50/60 Hz operation with 61850/MODBUS/DNP3 communications and projection-panel mounting, delivering reliable protection in medium-to-large power networks while simplifying integration with upstream protection schemes. This model delivers business value through selective tripping, reduced maintenance, and scalable performance, with Eaton’s warranty and compatibility with high-impedance modules as needed. Its compact projection mounting supports easy retrofit in existing panels.

FAQs
The EBR-3000-2B0KA1 is a high-impedance bus differential relay designed to protect large busbar and feeder networks in substations. It delivers selective protection to minimize nuisance trips, supports 50/60 Hz operation, and interfaces with substation automation protocols such as 61850, MODBUS, and DNP3 for fast fault identification and remote diagnostics.
Install the unit using the projection-panel mounting method, which is compatible with compact footprints. The device measures 7.49 in L x 8.62 in H x 6.82 in W and weighs 5.3 lb, enabling straightforward retrofits with minimal panel disruption while aligning with standard protection schemes.
Key electrical specs include a frequency rating of 50/60 Hz, a contact rating of 5 A ac/dc, and a burden of 10 W / 17 VA. The operating temperature range is -20°C to 60°C, ensuring reliable performance across typical industrial environments, with support for a high-impedance protection configuration when paired with the EBR-Z module.
The EBR-3000-2B0KA1 supports IEC 61850, MODBUS, and DNP3 (FO LC) for robust integration with modern protection schemes, SCADA systems, and remote monitoring. This enables faster fault isolation, data sharing, and centralized protection coordination across multi-vendor automation architectures.
Warranty terms follow Eaton’s policy: one year from installation or eighteen months from shipment, whichever occurs first. Maintenance typically involves periodic testing of protection functions, verification of communication links, and validation of high-impedance module compatibility to ensure continued selective protection and system reliability.
