High-impedance bus differential protection is the core feature, delivering targeted disturbance detection and selectivity that reduce nuisance trips while maintaining fast fault clearance on energized buses. In practice, this translates to fewer unplanned outages during transient faults and improved coordination with other protection devices on 50/60 Hz systems, making it ideal for large distribution buses in data centers, manufacturing facilities, and critical infrastructure. The MODBUS/DNP3 over RJ45 interface enables real-time monitoring, remote configuration, and seamless integration with SCADA and protection schemes, improving diagnostic efficiency and reducing on-site intervention time. Its standard mounting and compact footprint simplify retrofit projects, letting you upgrade protection without costly cabinet redesigns. With a 10 W / 17 VA burden and a 5 A contact rating, wiring and CT sizing stay manageable across typical installations.

FAQs
Installation is designed for standard equipment layouts with a standard mounting method. Ensure the panel has adequate space for the 7.49 in length, 8.62 in height, and 6.82 in width footprint and that mounting hardware aligns with the product’s mounting pattern. Route MODBUS/DNP3 RJ45 cables cleanly to a compatible control system, and verify bus differential wiring conforms to your feeder configuration to maximize protection performance.
The relay is designed for high impedance differential protection to improve selectivity on bus sections. It operates at 50/60 Hz, offers a 5 A contact rating, and requires the EBR-Z High Impedance Module for full functionality in certain configurations. This combination reduces nuisance trips while maintaining fast fault clearance, which is critical for large distribution buses.
Yes. The EBR-3000-2B0CA0 supports MODBUS/DNP3 over RJ45, enabling straightforward integration with SCADA systems and other protection devices. This enables remote monitoring, configuration, and event reporting, which shortens fault diagnosis cycles and improves protection coordination across distributed facilities.
The unit is specified for 50/60 Hz operation with a -20°C to 60°C operating range. It has a 5 A ac/dc contact rating and a burden of 10 W / 17 VA. The enclosure supports standard mounting, and the device is designed for typical protective relay environments found in power distribution, data centers, and manufacturing plants.
Eaton provides a warranty policy of one year from installation or eighteen months from shipment, whichever occurs first.
