Eaton Bus differential relay EBR-3Z-2B0KA1-B - 61850/MODBUS/DNP3
Part Number: EBR-3Z-2B0KA1-B
Quick Summary
Bus differential relay solutions protect high-impedance bus systems by delivering fast, selective protection for substations and feeder networks. Operators often struggle with nuisance tripping and protection coordination, especially during transient faults. This Eaton model aligns with industry expectations for reliability, featuring potential SIL-ready protection, CE compliance considerations, and a rugged enclosure for demanding environments. It supports 50/60 Hz operation, a 5 A contact rating, and a common bezel with the EBR-Z High Impedance Module, simplifying installation. With 61850/MODBUS/DNP3 communications and projection mounting, it enables scalable protection architectures while reducing maintenance costs and downtime for utility and industrial feeders.

FAQs
What mounting and clearance are required when installing the EBR-3Z-2B0KA1-B in a projection-panel environment? This model supports projection panel mounting and common bezel configurations with the EBR-Z High Impedance Module, enabling straightforward alignment with standard cabinets. Ensure adequate space for wiring, maintain required clearance for heat dissipation, and verify the panel is rated for -20 to 60°C ambient conditions to preserve performance and life.
Key parameters include 50/60 Hz operation, a 5 A contact rating, a burden of 10 W / 17 VA, and a projection-mount design. The relay is designed to perform under typical substations conditions, offering fast differential protection while maintaining signal integrity with 61850/MODBUS/DNP3 communications. Ensure compatible power and wiring to minimize nuisance trips and maintain coordination with upstream protections.
Yes. The EBR-3Z-2B0KA1-B is built for high-impedance bus differential scenarios, providing fast fault detection and selective tripping to protect bus bars and feeders. It integrates with common Eaton bezel modules, supports digital communication protocols, and is designed to simplify integration with modern SCADA and substation automation schemes while ensuring reliable protection in challenging environments.
Compliances are listed as Contact Manufacturer, so confirm the exact certifications with Eaton for your region. Typical concerns include CE marking for European compliance, SIL-ready protection for system reliability, and IP-rated enclosures for outdoor or harsh environments. Always verify current certifications prior to procurement to ensure regulatory alignment and project approval.
ROI stems from reduced outage duration, improved protection coordination, and lower maintenance labor due to modular bezel integration. The one-year warranty offers initial risk reduction. For ongoing value, implement periodic diagnostics via 61850/MODBUS/DNP3 interfaces, maintain firmware updates, and schedule routine testing of protection functions to sustain reliability and minimize unplanned downtime.
