Quick Summary

Eaton transformer relay is designed to protect and monitor power transformers in industrial and utility settings. It provides integrated protection logic, current protection and metering, and remote communication capabilities to reduce fault impact and downtime. This solution addresses the frequent challenge of transformer faults going undetected until severe damage or outages occur by delivering proactive monitoring and fast trip coordination. While explicit CE, SIL, or IP certifications are not listed in the datasheet, the unit relies on conformal-coated circuit boards and standards-aware interfaces to support harsh environments and safe integration with plant controls. With eight digital inputs, nine digital outputs, and a flexible power supply range of 19-300 Vdc or 40-250 Vac, it offers scalable protection without complicating installation.

FAQs

Plan for a front-access, projection-mounted enclosure; ensure 19-300 Vdc or 40-250 Vac supply is available; mount the unit with removable terminals for simplified wiring; connect 8 digital inputs and 9 digital outputs to the protection scheme; configure Modbus TCP or DNP3 TCP/UDP for SCADA integration; verify conformal coating suitability for the installation environment.
Key specs include 8 digital inputs, 9 digital outputs, power supply range of 19-300 Vdc / 40-250 Vac, 50/60 Hz operation, 5A/1A current sensing inputs, and the ability to support differential protection and current metering. Ensure system voltage, frequency, and communication protocols (Modbus TCP or DNP3) align with your plant controls and SCADA standards.
Yes. The ETR-4000-2A2CB1 is designed for transformer protection with differential protection, current protection and metering, trip-coil monitoring, and zone selective interlocking. Its Modbus TCP or DNP3 TCP/UDP interfaces enable integration with SCADA and data-center monitoring systems, supporting fast fault isolation and improved uptime.
The data sheet indicates Compliances as 'Contact Manufacturer', so verify CE, SIL, IP ratings, and related certifications directly with Eaton. Also confirm the device’s suitability for your regional regulatory requirements and ensure the conformal coating meets your environmental standards.
By consolidating protection logic, metering, and remote communication in a single device, the ETR-4000-2A2CB1 reduces wiring, panel space, and downtime during fault events. Its robust design and removable terminals ease maintenance and upgrades, delivering faster diagnostics and potentially lower lifecycle costs through improved transformer protection and SCADA visibility.
