Eaton EBR-3000-2B0HB1 Bus Differential Relay - High-Impedance
Part Number: EBR-3000-2B0HB1
Quick Summary
Eaton Bus differential relay protects bus sections by detecting faults in feeder connections. In modern power systems, nuisance trips and slow fault isolation threaten uptime and safety, and engineers frequently wrestle with balancing sensitivity and selectivity. Compliance details are issued by the manufacturer; typical certifications for industrial relays include CE marking, IP protection, and functional safety approvals depending on regional requirements—confirm the exact status with Eaton. The device offers 50/60 Hz operation, a 5 A contact rating, and 61850/MODBUS/DNP3 communications, along with a conformal coating and projection-mount design for reliable integration into existing control architectures. Used in substations and switchgear, it supports scalable protection strategies and improved ROI through streamlined maintenance and remote monitoring.

High-impedance protection with optional EBR-Z module provides robust differential protection across bus sections, reducing nuisance trips and enabling faster isolation of faults. This translates to improved reliability and less unplanned downtime in critical power distribution paths. The RJ45 61850/MODBUS/DNP3 communications simplify integration with SCADA, EMS, and other control layers, enabling remote monitoring and faster fault diagnosis in industrial automation environments. Conformal coating and projection-panel mounting enhance durability in harsh electrical cabinets and tight spaces, lowering installation risk and post-installation failures. A lightweight yet capable package delivers a 5 A contact rating and a modest 10 W / 17 VA burden, which supports straightforward wiring and compatibility with standard trip circuits while preserving system energy efficiency. The unit operates from -20°C to 60°C and supports 50/60 Hz systems, making it suitable for diverse electrical rooms; Eaton’s warranty and documented support help secure long-term ROI and predictable maintenance costs.

FAQs
Plan for projection-panel mounting and verify panel space for the unit's 7.49 in depth, 8.62 in height, and 6.82 in width. Ensure the compatible EBR-Z High Impedance Module is available if full high-impedance protection is required. Use the RJ45 port for 61850/MODBUS/DNP3 communications and account for the 10 W / 17 VA burden in protection circuit design.
A 5 A contact rating suits signaling and protective interlock applications within typical feeder circuits while supporting reliable tripping under fault conditions. In practice, the rating helps balance fast fault clearance with secure, nuisance-free operation when integrated with appropriate CT/SCADA logic and the high-impedance module as needed.
Yes. The relay is designed for 50/60 Hz operation and operates across a -20°C to 60°C range, making it compatible with a broad set of industrial substations and switchgear environments where robust, fast differential protection is required.
Compliance details are provided by the manufacturer. Typical certifications for industrial protection relays include CE marking and regional safety certifications; IP ratings and functional safety approvals vary by region. Contact Eaton for the latest certificates and documentation specific to your installation locale.
The rugged design with conformal coating reduces corrosion risk in demanding environments, lowering maintenance frequency. The device’s integration with standard communication protocols streamlines diagnostics, reducing maintenance labor and MTTR. A 1-year warranty (or 18 months from shipment) provides short-term protection while enabling long-term cost predictability.
