Eaton EBR-3Z-2B0TA0-B Bus differential relay - High Impedance
Part Number: EBR-3Z-2B0TA0-B
Quick Summary
Eaton Bus differential relay protects bus sections by detecting differential currents in power distribution networks. Engineers often struggle to coordinate protection schemes across modular bus bars while maintaining fast, reliable trips. Compliances require manufacturer confirmation; consult Eaton for specifics on any SIL, CE, or IP-related certifications. This module supports 61850/MDBS/DNP3 (RS485 RJ45) and standard mounting, delivering robust protection with a compact footprint. The combination of protection intelligence and straightforward installation helps accelerate projects, reduce downtime, and simplify integration with Eaton’s protection ecosystem, enabling better reliability across industrial automation and power distribution architectures.
