Eaton ETR-4000-2A2DA1 Transformer Relay - Profibus-DP
Part Number: ETR-4000-2A2DA1
Quick Summary
Eaton transformer relay ETR-4000-2A2DA1 provides advanced transformer protection for electrical substations and industrial plants. When protection schemes miss a fault, downtime and costly outages follow; this device delivers precise differential protection, current protection, and metering to prevent that. Compliance details are set by the manufacturer and regional standards may require CE or other certifications; verify applicable certifications for your installation. In addition to core protection, the unit offers Profibus-DP communication over fiber, 8 digital inputs, 9 digital outputs, and versatile power ranges from 19-300 VDC to 40-250 VAC, enabling easy integration in existing switchgear and control panels, reducing wiring complexity and improving maintenance efficiency.

FAQs
The ETR-4000-2A2DA1 is designed for projection mounting with removable terminals, simplifying panel integration. It offers 8 digital inputs and 9 digital outputs, plus two current-sensing inputs, enabling straightforward wiring and test access. Plan for compatible power supply and ensure Profibus-DP fiber connectivity is routed to the control network for reliable communications.
Key protections include differential protection, current protection and metering, and zone selective interlocking (2 zones). These features enable fast fault detection and selective tripping, reducing fault spread, improving stability, and lowering maintenance costs in transformer-driven applications.
Yes, it supports Profibus-DP over fiber optic ST. This delivers EMI resistance, longer cable runs, and robust network integration with existing PLCs and SCADA systems, simplifying remote monitoring and coordination across substations and industrial facilities.
Compliances are listed as 'Contact Manufacturer' for this model, so verify region-specific certifications with Eaton. In practice, transformer protection relays often require CE or equivalent safety and electrical standards; confirm exact certifications for your installation to ensure regulatory compliance and warranty validity.
Warranty follows Eaton's policy: one year from installation or eighteen months from shipment, whichever occurs first. For ROI, prioritize reduced downtime through fast fault isolation, minimize unplanned outages with comprehensive protection, and simplify maintenance via modular I/O and testability, all of which lower lifecycle costs.
