Quick Summary

The Eaton transformer relay ETR-5000-2A1FA0 provides advanced transformer protection and monitoring across electrical networks, combining protection, metering, and remote-control capabilities in a single package. Engineers often struggle with reliable protection coordination, accurate fault detection, and seamless communications to field devices under variable load and harsh environmental conditions. Certification expectations vary by region; confirm CE compliance, SIL-rated options, and IP-rated enclosures with Eaton for your installation, site requirements, and regulatory obligations. Its modular I/O, fiber-optic communications for Modbus RTU or DNP3 RTU, and 8/9 I/O counts enable scalable protection schemes that reduce wiring and commissioning time while improving uptime for OEMs and end users.

FAQs

To install, supply the unit with 19-300Vdc or 40-250Vac within 50/60 Hz, connect 8 digital inputs and 9 outputs, and wire the two current-sensing inputs as required. Use the removable terminals for quick field terminations and the semi-flush mounting for secure cabinet fit. For communication, configure Modbus RTU or DNP3 RTU over Fiber Optic ST to integrate with your SCADA suite.
Key specs include a 19-300Vdc / 40-250Vac power range, 50/60 Hz operation, 8 digital inputs, 9 digital outputs, and 2 current-sensing inputs. The unit supports 5A and 1A phase current options, with Modbus RTU or DNP3 RTU via fiber for robust, long-distance communication and fast fault signaling.
Yes. The ETR-5000-2A1FA0 is designed as a transformer protection relay with multi-sensor protection and metering capabilities, zone selective interlocking, and time-synchronization features (IRIG-B). Its fiber communications and flexible I/O enable reliable protection coordination in substations and utility-grade OEM equipment.
Compliances are listed as manufacturer-specific; verify CE, SIL readiness, and enclosure IP ratings directly with Eaton for your region and installation. Always obtain certification documentation from Eaton to ensure the device meets your site’s safety and reliability requirements before deployment.
The Eaton policy provides a one-year warranty from installation or 18 months from shipment, whichever comes first. The device’s removable terminals, compact semi-flush mounting, and integrated I/O reduce maintenance time and wiring errors, delivering lower total cost of ownership and faster commissioning for OEMs and end users.
