Eaton EBR-3Z-2B0KA0-B Bus differential relay - 61850
Part Number: EBR-3Z-2B0KA0-B
Quick Summary
EBR-3Z-2B0KA0-B bus differential relay is a high-impedance protection device that safeguards shared bus configurations in industrial power systems. Engineers face nuisance trips and integration challenges when protecting bus sections across multi-vendor control layers, which can drive outages and increase maintenance. This Eaton relay supports industry-standard communications, including 61850, MODBUS, and DNP3, and ships in a common bezel with the EBR-Z high-impedance module for modular expansion. With standard mounting and a robust -20° to 60°C operating range, it delivers reliable operation in harsh environments. By combining precise protection with scalable integration, the solution reduces engineering time and supports efficient, compliant protection architectures.

High-impedance protection architecture reduces nuisance trips and improves selectivity across shared bus sections, delivering more reliable feeder protection and lower outage costs. Business impact: fewer false trips, faster fault isolation, and smoother integration with SCADA and automation systems. Application: suitable for large electrical distribution buses in manufacturing, utilities, and data centers where robust cross-bus protection is essential. The common bezel with the EBR-Z high-impedance module enables modular expansion, swapping in protective modules without replacing the entire enclosure. This minimizes retrofit time and reduces total installed cost. The device supports 61850, MODBUS, and DNP3 communications, enabling straightforward integration with modern control architectures and asset management. Operational burden is kept low with a 10 W / 17 VA burden and standard mounting for quick, reliable installs. Rugged -20° to 60°C operation expands deployment in harsh environments while the 5 A contact rating provides solid control interface compatibility with protection schemes. The warranty, one year from installation or eighteen months from shipment, adds business certainty for procurement and maintenance planning. Together, these features deliver measurable gains in protection reliability, maintenance predictability, and overall lifetime return on investment.

FAQs
The EBR-3Z-2B0KA0-B uses standard mounting with a common bezel, designed for straightforward retrofit in typical 19-inch rack environments. Ensure adequate clearance for heat dissipation and access for wiring, and follow manufacturer installation guidelines for bus differential connections to maintain high-impedance protection integrity. The unit supports modular expansion via the EBR-Z high-impedance module, simplifying future upgrades without replacing existing enclosures.
Key specs include a 50/60 Hz frequency rating, 5 A contact rating (AC/DC), and a burden of 10 W / 17 VA. The device weighs 12.7 lb and has dimensions of 7.49 in depth, 8.62 in height, and 13.64 in width. Operating temperature ranges from -20°C to 60°C, making it suitable for harsh environments while maintaining protective accuracy and response speed.
This relay excels in utilities, data centers, and industrial facilities with shared bus architectures where reliable protection and fast fault isolation are critical. It supports modular protection schemes, scales with system growth, and integrates with modern automation stacks via 61850, MODBUS, and DNP3, reducing engineering time and enabling centralized monitoring of protection performance.
Compliances are listed as Contact Manufacturer, meaning regional certifications should be confirmed with Eaton or the authorized distributor. The product features standard protection capabilities and communications compatibility (61850/MODBUS/DNP3), which supports compliance with modern substation and industrial automation environments—verify regional requirements for CE, SIL, or IP ratings as applicable to your installation.
With 50/60 Hz operation, 5 A contacts, and a robust operating range (-20°C to 60°C), the relay offers long-term protection with minimal maintenance. The modular bezel design facilitates upgrades without equipment downtime, reducing future upgrade costs. A one-year warranty from installation (or 18 months from shipment) provides a predictable total cost of ownership and supports a favorable return on investment through improved reliability and system uptime.
