Eaton Bus differential relay EBR-3Z-2B0DA1-B Profibus-DP
Part Number: EBR-3Z-2B0DA1-B
Quick Summary
Eaton Bus differential relay protects feeders in industrial electrical systems, delivering fast, selective fault isolation. Engineers often struggle to fit protective relays into legacy panels while maintaining Profibus-DP communications and cross‑voltage compatibility. Certifications commonly considered in the field include CE marking, SIL readiness for safety-critical operation, and IP-rated enclosures; verify exact details with Eaton. With eight digital inputs, six digital outputs, and a broad power range, the EBR-3Z-2B0DA1-B simplifies installation, reduces spare parts, and improves overall feeder protection reliability across industrial facilities.
