FAQs

Begin by verifying the base relay compatibility (ETR-4000) and mapping the 8 digital inputs and 9 outputs to your protection scheme. Use the projection mounting for rapid alignment and removable terminals to simplify wiring. Plan RS-485 Modbus RTU or TCP/IP Ethernet integration for remote monitoring, and confirm power supply within 19-300Vdc or 40-250Vac to ensure reliable operation.
Key specs include the 50/60 Hz frequency tolerance, dual power-supply ranges (19-300Vdc, 40-250Vac), 8 DI and 9 DO I/O, and two current-sensing inputs. These enable precise voltage, current, and differential protections, reducing nuisance trips. The IRIG-B/Trip Coil Monitor options further enhance synchronization and reliability in complex networks.
Yes. The ETR-5000-2A0IB1 is designed for transformer protection in both substations and OEM applications. It supports Modbus communications over RS-485 and Ethernet, zone selective interlocking, and multiple metering protections, making it adaptable for new builds and modernization projects while offering a scalable upgrade path via the ETR-4000 base.
Compliances are listed as region-specific and require confirmation with Eaton. For projects with CE, SIL, or IP rating requirements, contact Eaton to confirm current certifications applicable to your locale and installation type. This ensures regulatory alignment and reduces rework during audits or system startup.
Maintenance focuses on ensuring clean terminals, periodic verification of communication links (RS-485, Ethernet), and monitoring for terminal wear due to removable connectors. ROI is driven by reduced downtime through reliable protection, easier upgrades from older relays, and improved visibility with remote monitoring, which lowers field service costs and accelerates fault diagnosis.
