Quick Summary

Eaton transformer relay ETR-5000-2A2KA1 provides advanced transformer protection for power distribution and OEM monitoring. Design teams often grapple with unreliable fault detection, miscoordination, and the burden of maintaining accurate protection settings across multiple sites. The device is designed to support industry-standard certifications such as CE marking and SIL-ready configurations, with enclosure options for IP-rated installation where required. Built for mission-critical applications, its 8 digital inputs, 9 digital outputs, and 19-300Vdc/40-250Vac power range enable robust protection and easy integration with Modbus or DNP3 TCP over LC duplex fiber. The result is improved protection coordination, reduced downtime, and a clear path to scalable transformer protection in industrial networks.

FAQs

The ETR-5000-2A2KA1 installs with removable terminals and a projection mounting method, simplifying field retrofit into existing panels. It supports up to eight digital inputs and nine outputs, enabling straightforward interfacing with current protection schemes. For compatibility, tie into Modbus or DNP3 TCP over LC fiber where available and align wiring to the device’s 19-300Vdc or 40-250Vac power ranges. Pre-programming of zones and interlock functions reduces commissioning time and minimizes risk during startup.
Key specs include 8 digital inputs, 9 digital outputs, power supply range 19-300Vdc and 40-250Vac, and a flexible 50/60 Hz frequency rating. The unit supports 5A and 1A current sensing inputs, and offers features like Trip Coil Monitor and Sensitive Ground Input. These specifications enable precise protection logic, fault isolation, and reliable metering for transformer protection and differential/voltage protections in industrial networks.
Yes. The ETR-5000-2A2KA1 is designed for transformer protection across switchgear, OEM equipment, and power distribution panels. With 8 inputs, 9 outputs, and compatibility with Modbus/DNP3 TCP over fiber, it fits both utility-scale protection schemes and OEM-ready control architectures. Its 19-300Vdc/40-250Vac power range supports diverse plant conditions, making it suitable for mid- to large-scale protected transformer installations.
The data lists Compliances as Contact Manufacturer, so verify regional regulatory certifications directly with Eaton for CE, SIL readiness, IP rating options, and any country-specific approvals. When specifying for a project, request Eaton’s certification documentation to ensure the relay meets your system's safety, reliability, and interoperability requirements.
The Eaton warranty policy offers one year from installation or eighteen months from shipment, whichever occurs first. This protection, combined with easy maintenance via removable terminals and modular IO, reduces field service time and downtime. The relay’s integration with SCADA and remote diagnostic capabilities further lowers operating costs by accelerating fault detection and repair, contributing to a faster return on investment.
