Eaton ETR-4000-2A0KA1 Transformer Relay - 50/60 Hz

Feature: Eight digital inputs and nine digital outputs enable flexible interlocking and control schemes. Business Impact: Reduces panel complexity and wiring runs while enabling precise protection logic and fast fault isolation. Application: Transformer protection schemes in substations or industrial plants benefit from richer I/O without adding hardware depth. Feature: Wide power supply range of 19-300 VDC and 40-250 VAC, plus 50/60 Hz operation. Business Impact: Unifies supplies across varying installation environments, lowering the cost of panel variants and retrofits. Application: Suitable for new builds and spare-part upgrades in diverse industrial facilities. Feature: Removable terminals and projection mounting for easy installation and retrofit. Business Impact: Speeds commissioning, reduces commissioning risk, and simplifies field maintenance. Application: Preferred for retrofit projects in existing switchgear and compact control rooms. Feature: I/O options including IRIG-B Trip Coil Monitor and URTD Interface with Modbus/DNP3 TCP over LC duplex fiber Ethernet. Business Impact: Enables precise timing, reliable trip coordination, and secure remote diagnostics across plant networks. Application: Critical for high-integrity transformer protection, remote monitoring, and integration with PowerPort-E. Feature: Differential protection, current protection and metering sensing with 5 A / 1 A phase currents. Business Impact: Enhanced fault detection accuracy and improved protection coordination, reducing nuisance trips. Application: Protective relaying in transformer feeder banks and critical power trains. Feature: Zone Selective Interlocking with two interlock channels. Business Impact: Improves fault isolation speed and minimizes damage during transients. Application: Essential in systems with multiple transformers sharing bus sections and feeders.
