Quick Summary

ETR-4000-2A2HA1 transformer relay is a protection device for transformer networks in industrial automation. It provides advanced transformer protection and metering with Ethernet-based communications for modern substations. This unit addresses the common pain point of slow fault isolation and manual signal routing by offering 61850, Mbus TCP, and DNP3 TCP/UDP over an RJ45 connection. Note: public certifications such as SIL, CE, or IP ratings are not listed here; consult Eaton for current approvals. Built for reliability, it combines flexible I/O, programmable protection logic, and scalable communication to align with evolving asset-management strategies, while supporting 50/60 Hz operation and a broad power-supply range to simplify integration in existing plants.

FAQs

This unit uses removable terminals and a projection mounting method, enabling quick wiring and straightforward retrofit into most transformer protection panels. It supports Ethernet-based communications (61850, M-Bus TCP, DNP3 TCP/UDP over RJ45) for seamless integration with existing protection relays and substation networks.
Key specs include eight digital inputs, nine digital outputs, two current sensing inputs, and phase current ratings of 5A and 1A. It operates on a power-supply range of 19-300 Vdc or 40-250 Vac and supports 50/60 Hz. Communication is over Ethernet RJ45 with IEC 61850, M-Bus TCP, or DNP3 TCP/UDP.
Yes, it fits transformer protection and monitoring in data centers and industrial facilities, especially where Ethernet-based protocols are used. The 8/9 I/O configuration, along with differential protection capabilities and metering, supports fast fault isolation and asset management in medium to large transformer installations.
Public certification details such as SIL, CE, or IP ratings are not listed in the provided data. For current certification status and approvals, contact Eaton directly to confirm the product’s compliance for your region and application.
Warranty is defined by Eaton Selling Policy 25-000 as one year from the date of installation or eighteen months from shipment, whichever occurs first. This protection, combined with easier installation, reduced commissioning time, and scalable Ethernet connectivity, can lower total cost of ownership by reducing downtime and service charges.
