Eaton EBR-3000-2B0TA0 Bus Differential Relay - Hi-Z
Part Number: EBR-3000-2B0TA0
Quick Summary
The Eaton Bus differential relay EBR-3000-2B0TA0 delivers high-impedance protection for bus sections in power distribution networks. Engineers face nuisance trips and slower fault isolation; this relay helps minimize those issues through precise differential protection. While the unit supports 61850/MDBS/DNP3 communications over RS485 RJ45, specific SIL, CE, or IP certifications should be confirmed with Eaton. In addition, its standard mounting, 5 A contact rating, and 50/60 Hz operation align with common installation practices and the needs of modern substations and plant feeders. The device’s compact footprint and broad temperature range support reliable performance in demanding environments, delivering tangible business value through improved uptime and easier maintenance.

Feature: High-impedance bus differential protection implemented in the EBR-3000-2B0TA0 delivers precise fault discrimination. Business impact: Reduces nuisance trips and improves system uptime by isolating faults within the bus rather than elsewhere in the network. Application: Ideal for medium to large switchgear and substations where fast, selective protection is essential. Feature: 61850/MDBS/DNP3 communications over RS485 RJ45 enable seamless substation automation. Business impact: Enables remote monitoring, centralized configuration, and faster fault analysis, reducing diagnostic time. Application: Integrates with modern IEC 61850/ MDBS/ DNP3 based SCADA and protection schemes. Feature: Standard mounting and a compact enclosure (7.49 in length, 8.62 in height, 6.82 in width). Business impact: Simplifies retrofits and shortens installation cycles, lowering project risk. Application: Fits into existing panel footprints with minimal rework. Feature: Burden of 10 W / 17 VA and 5 A contact rating (ac/dc). Business impact: Low power draw combined with robust signaling capability reduces heat and wiring complexity. Application: Suitable for plant signaling, alarms, and interlocks without extra interface relays. Feature: Operating temperature range from -20°C to 60°C. Business impact: Ensures reliable protection across harsh environments and varying industrial climates. Application: Reliable in outdoor substations, factories, and process facilities. Feature: Warranty and support terms. Business impact: Provides procurement assurance and lifecycle cost predictability. Application: Helps with budgeting, maintenance planning, and supplier continuity.

FAQs
The EBR-3000-2B0TA0 uses standard mounting and a compact enclosure suitable for existing switchgear footprints. For full high-impedance operation, the EBR-Z High Impedance Module is required. Plan RS485 RJ45 connections for 61850/MDBS/DNP3 communication and ensure wiring meets local electrical codes for protection relays and bus protection schemes.
Yes. The relay includes 61850/MDBS/DNP3 over RS485 RJ45, enabling integration with modern substation automation systems. This supports centralized monitoring, configuration, and fault analysis, reducing field trips and accelerating response times in coordinated protection schemes.
Key specs include a 5 A ac/dc contact rating, 50/60 Hz frequency, -20°C to 60°C operating range, and a burden of 10 W / 17 VA. The unit is designed for standard mounting, with a catalog number EBR-3000-2B0TA0 and a 7.49 in × 8.62 in × 6.82 in footprint.
Warranty coverage is Eaton's policy: one year from installation or 18 months from shipment, whichever occurs first. Compliance details are listed as 'Contact Manufacturer' for specific regulatory certifications, so confirm with Eaton for your region and applicable standards prior to deployment.
The EBR-3000-2B0TA0 reduces maintenance overhead by improving fault discrimination, minimizing misoperations, and enabling remote monitoring via 61850/MDBS/DNP3. Its standard mounting and modest power burden simplify wiring, while compatibility with the Hi-Z module supports long-term protection strategy without frequent hardware swaps, lowering lifecycle costs.
