Eaton EBR-3000-2B0HA0 Bus Differential Relay - 50/60 Hz
Part Number: EBR-3000-2B0HA0
Quick Summary
EBR-3000-2B0HA0 is a bus differential relay that protects power buses by quickly detecting faults across bus sections. Engineers often struggle with nuisance trips and slow diagnostics in traditional protection schemes; this device delivers selective, high-impedance protection. Designed for 50/60 Hz systems and supporting 61850, MODBUS, and DNP3 communications, it integrates with standard protective relays and modern substation architectures. Warranty terms follow Eaton's policy: one year from installation or 18 months from shipment, whichever occurs first. Compliance specifics should be verified with Eaton; when paired with the EBR-Z High Impedance Module, it enables robust bus differential protection with clear diagnostics and faster fault isolation. This combination translates to improved reliability and actionable insights for asset management.

High impedance bus differential protection sits at the core of the EBR-3000-2B0HA0. When paired with the EBR-Z High Impedance Module, it delivers highly selective fault detection across protected bus sections, reducing misoperations and outage duration. This configuration supports faster clearance and minimized customer impact in congested feeder networks. Connectivity via 61850, MODBUS, and DNP3 over RJ45 enables straightforward integration with modern substations and SCADA systems. The business impact is improved visibility, faster fault isolation, and simpler commissioning in mixed automation architectures. Operators can leverage standard protocols to interrogate protection status and alarms without custom translation layers. Installation is eased by standard mounting and a compact footprint, with a unit weight of 5.3 lb and a burden of 10 W / 17 VA, helping maintain overall protection system efficiency. The electrical design supports a 50/60 Hz frequency rating and a 5 A contact rating for reliable signaling in industrial environments, while the -20°C to 60°C operating range accommodates harsh plant conditions. Deployment within Eaton protection ecosystems is straightforward, and the warranty terms support long-term lifecycle planning.

FAQs
Begin with confirming system compatibility and power up the EBR-3000-2B0HA0 in standard mounting configuration. Install the EBR-Z High Impedance Module per the manufacturer’s guidelines to enable high-impedance protection. Wire the RJ45 communications interface for 61850, MODBUS, or DNP3 as required and verify signal integrity with the protection scheme in the control room. Finally, perform a factory reset and run functional tests to confirm accurate differential protection and alarm reporting.
Key specs include a 50/60 Hz frequency rating, 5 A contact rating for signaling, and a 10 W / 17 VA burden. Operating temperature ranges from -20°C to 60°C, with a standard mounting footprint of 7.49 in x 8.62 in x 6.82 in and a weight of 5.3 lb. The device supports RJ45 connectivity for 61850/MODBUS/DNP3, enabling integration with common protection and automation systems.
Yes, the relay is designed for bus protection in industrial distribution and substation contexts, including data centers where high reliability and fast fault isolation are critical. Its 50/60 Hz compatibility, standard mounting, and compatible communications interfaces (61850/MODBUS/DNP3) support integration into modern protection architectures. Pairing with the EBR-Z module enhances selectivity, which helps minimize unplanned outages in mission-critical facilities.
Certification specifics should be confirmed with Eaton representatives. The data sheet notes ‘Compliances: Contact Manufacturer,’ so regional standards (CE, UL, IEC) may vary by deployment. Before procurement, verify applicable certifications for your site, along with warranty terms (one year from installation or 18 months from shipment) and any region-specific installation guidelines.
The EBR-3000-2B0HA0 offers faster, more selective fault isolation, reducing outage duration and associated repair costs. Its compatibility with standard protection schemes and minimal retrofit effort lowers commissioning time and labor costs. Regular maintenance primarily involves verification of protection settings, communication interfaces, and module integrity, with the assurance of Eaton’s warranty support for lifecycle reliability.
