FAQs

Install the ETR-4000-2A1CA1 using its removable terminals and projection mounting to minimize wiring and mounting depth. Ensure the unit is powered from 19-300Vdc or 40-250Vac and connected to 8 digital inputs and 9 digital outputs as required by your transformer protection scheme. Use the URTD interface for extended monitoring options and confirm Ethernet connectivity for Modbus TCP or DNP3 communication to your SCADA system.
The relay provides two current sensing inputs for current protection and metering, with configurable protection logic suitable for transformer protection schemes. It supports 5A and 1A current sensing ranges and operates at 50/60 Hz. Sensing inputs and zone selective interlocking help improve selective tripping and fault isolation, reducing unneeded outages.
Yes, it is designed as a transformer protection relay with 8 DI and 9 DO, multiple power options, and Ethernet communications for SCADA integration. Its protection features, including differential and current protection, along with time synchronization options like IRIG-B, make it suitable for transformer protection in substations and industrial facilities.
Certification specifics are not listed in the provided data. To verify compliance, contact Eaton directly to confirm CE, SIL, IP ratings, and any other regulatory certifications required for your installation location and industry standards.
