Quick Summary

The Eaton transformer relay ETR-5000-2A2HA1 protects transformers and enables advanced monitoring in electrical distribution systems. Engineers often struggle with slow fault isolation, limited remote diagnostics, and difficult integration across IEC 61850, M-Bus TCP, and DNP3 networks. Compliance status is listed as 'Contact Manufacturer' but the unit supports interoperability through 61850, Mbus TCP, and DNP3 TCP/UDP over Ethernet RJ-45. With a flexible power range and expanded I/O, the relay reduces downtime, streamlines panel wiring, and supports scalable protection schemes for utilities and OEMs. It blends robust protection with future-proof communications to simplify upgrades and maintenance in modern electrical grids.

FAQs

The unit features removable terminals and projection mounting, which simplifies wiring and panel installation. With eight digital inputs and nine outputs, plus two current sensing inputs, it can be wired efficiently in compact switchgear or panel boards, reducing field labor time and errors.
It provides differential protection, current protection and metering, voltage protection and metering, and power protection and metering. This combination improves fault detection accuracy, minimizes nuisance trips, and supports precise protection coordination across transformer assets.
Yes. With 50/60 Hz capability, broad input/output capabilities, and Ethernet communications (61850, Mbus TCP, DNP3 TCP/UDP), the relay is designed for transformer protection in substations, OEM panels, and industrial power systems, enabling scalable protection architectures.
Compliance details are listed as 'Contact Manufacturer' in the data set. The device supports standard interoperability protocols (61850, Mbus TCP, DNP3) for integration, and Eaton provides formal certification information through its documentation and support channels.
Warranty is governed by Eaton’s policy, with one year from installation or eighteen months from shipment, whichever occurs first. This provides a defined period of support and helps with total cost of ownership and planning for maintenance cycles.
