FAQs

Plan for seamless upgrade by verifying mounting method (semi-flush) and removable terminals. The ETR-5000-2A3CB0 is designed to be compatible with the ETR-4000 base relay family, enabling commonality in wiring and a single maintenance routine. Ensure correct I/O mapping (8 DI, 9 DO) and confirm the network interface (Ethernet RJ-45) for Modbus TCP or DNP3 networking.
Key specs include 8 digital inputs, 9 digital outputs, 2 current sensing inputs, power supply range from 19–300 Vdc or 40–250 Vac, and a 50/60 Hz frequency rating. Communication is via Modbus TCP or DNP3 TCP/UDP over Ethernet RJ-45, with URTD Interface and IRIG-B timing support for synchronized protection.
Yes. It’s designed as a transformer protection relay with metering capabilities, supports zone selective interlocking (2), and offers robust communications for SCADA integration via Modbus TCP or DNP3. Its rugged input/output configuration and timing features make it appropriate for substation protection schemes and reliable fault isolation.
Certification details are not listed in the provided data. Confirm CE marking, SIL readiness, IP ratings, and other project-specific certifications directly with Eaton to ensure alignment with your regulatory and safety requirements.
Warranty follows Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. Regular maintenance is typically focused on connector integrity and Ethernet communications; schedule periodic checks of IO status, timing accuracy (IRIG-B), and relay health to maintain protection reliability and minimize downtime.
