Flexible I/O and power compatibility: The ETR-4000-2A1DA0 supports eight digital inputs, nine digital outputs, and two current sensing inputs, enabling sophisticated protection logic without excessive wiring. A dual power range—19-300 Vdc or 40-250 Vac at 50/60 Hz—lets you reuse existing power supplies and cabinet layouts, reducing wiring complexity and commissioning time. This is ideal for transformer protection in retrofit projects, OEM equipment, and industrial substations, where quick integration and reliable operation minimize change orders. Comprehensive protection and metering: Sensing inputs cover current protection and metering, with differential protection to catch internal faults. Zone selective interlocking (two zones) improves selectivity, limiting fault impact and speeding restoration. Together, these features reduce unplanned downtime and extend asset life by providing early warning and precise fault localization. Robust networking and field compatibility: Profibus-DP communication over fiber optic ST delivers EMI resistance and dependable performance in noisy environments. URTD interface, Trip Coil Monitor, Sensitive Ground Input, and IRIG-B time synchronization simplify trip coordination and integration with existing protection schemes, lowering engineering risk when expanding to new transformers. Installation efficiency and reliability: Removable terminals and semi-flush mounting streamline installation in compact cabinets, while rugged construction supports operation across temperature and vibration ranges typical of power facilities. Warranty follows Eaton’s policy of one year from installation or 18 months from shipment, whichever occurs first, enabling predictable lifecycle budgeting. Field-proven business value: The ETR-4000-2A1DA0 combines protection, monitoring, and diagnostics in a single relay, enabling faster fault localization, improved asset protection, and lower total cost of ownership across distributed power systems.

FAQs

Begin by assigning the eight digital inputs and nine digital outputs to the protection logic you require, then connect the two current sensing inputs to the monitored feeders. Power the unit with the specified 19-300 Vdc or 40-250 Vac supply at 50/60 Hz. Use the removable terminals to simplify field wiring, and verify proper grounding and isolation per Eaton installation guidelines to ensure reliable protection coordination.
Key specs include eight digital inputs, nine digital outputs, two current sensing inputs, a power supply range of 19-300 Vdc or 40-250 Vac, and a 50/60 Hz frequency rating. Communications are via Profibus-DP over fiber optic ST. Phase current ranges are 5 A and 1 A, with zone selective interlocking available for two zones, supporting robust transformer protection and fast fault isolation.
Yes. The unit supports zone selective interlocking with two zones, enabling coordinated protection across adjacent transformers. This feature helps limit arc-and-fault propagation, reduces outage impact, and simplifies post-fault analysis, making it well-suited for substations and multi-transformer installations where selective tripping is critical.
Certification details vary by region and installation. The Eaton ETR-4000-2A1DA0 documentation indicates ‘Compliances: Contact Manufacturer,’ so verify with Eaton for CE, SIL, IP, or other regional approvals applicable to your site. Coordinate with your procurement and engineering teams to ensure all required standards are met before deployment.
By consolidating protection, monitoring, and diagnostics into a single relay with flexible I/O and trusted Profibus-DP communication, you can shorten commissioning, reduce wiring complexity, and improve fault pinpointing. These factors translate to lower downtime, faster maintenance cycles, and a lower total cost of ownership across transformer protection schemes.
