FAQs

The ETR-5000-2A0DA0 is designed to work with the ETR-4000 base as a plug-in transformer protection relay. It provides eight digital inputs, nine digital outputs, and two current sensing inputs. Installation should follow Eaton’s mounting and termination guidelines, using removable terminals for quick field servicing and cables sized for 19-300 VDC or 40-250 VAC inputs. Plan I/O around protection, metering, and signaling needs to ensure efficient, lockable interlocks with Zone Selective Interlocking features.
The device supports a broad power range: 19–300 VDC and 40–250 VAC, with a frequency rating of 50/60 Hz. This flexibility allows deployment across varied plant voltage architectures and simplifies retrofits or OEM integration, reducing need for additional power conditioning equipment while maintaining accurate protection and metering functions.
This transformer protection relay is well suited for OEM equipment, transformer protection in manufacturing facilities, and distribution networks. It supports current and voltage protection and metering, differential protection, and power protection metering, with robust fieldbus connectivity for remote monitoring and control in substations, switchyards, and process plants.
Certification specifics should be confirmed with the manufacturer for your region. Typical considerations include CE marking and SIL compliance, plus enclosure IP ratings appropriate to your installation environment. The Eaton documentation notes Compliances as 'Contact Manufacturer', so verify exact approvals, installation conditions, and any region-specific standards before purchase or field deployment.
Expect improved protection reliability and faster fault isolation thanks to integrated protection, metering, and diagnostics. The device offers a one-year warranty (or 18 months from shipment, whichever occurs first) and supports modular, removable-terminals design for easier servicing. Remote diagnostics and tight integration with Profibus-DP reduce downtime, optimize maintenance scheduling, and lower total cost of ownership over transformer assets.
