Quick Summary

Eaton transformer relay ETR-5000-2A3LA1 is a transformer protection relay delivering integrated protection, metering, and communication for industrial power systems. Operators often face fragmented protection schemes and long commissioning cycles, which increase downtime and risk for critical equipment. While exact certifications should be confirmed with Eaton, transformer protection relays in this class typically support CE marking and robust enclosure ratings to withstand harsh environments. With Modbus TCP and DNP3 TCP/UDP over LC fiber Ethernet, plus flexible power inputs, it streamlines integration and accelerates time-to-value for utilities and large facilities.

Eight digital inputs, nine digital outputs, and two current sensing inputs provide comprehensive protection logic, remote signaling, and metering options in a single device. This reduces reliance on external I/O modules, minimizes wiring errors, and shortens cabinet footprint, which lowers installation time and material costs. In transformer protection scenarios, these I/O capabilities support conditional logic, trip signaling, and status reporting aligned with zone selective interlocking strategies. Power supply versatility is a key advantage: 19-300 Vdc and 40-250 Vac input ranges allow a single device to serve multiple sites with different electrical standards. This eliminates the need for multiple variants, streamlining procurement and spare-part management. For upgrades or retrofit projects, the consistent input range ensures predictable protection behavior without re-engineering the power architecture. Communications leverage Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet, enabling fast, secure data exchange with SCADA, energy meters, and protection relays. This reduces wiring complexity and improves diagnostic visibility through standardized protocols. The dual-fiber option also enhances resilience in noisy industrial environments. I/O options extend protection capabilities: IRIG-B Trip Coil Monitor, URTD Interface, and Sensitive Ground Input support precise trip timing, remote monitoring, and enhanced ground fault detection. With these signals, engineers can implement accurate protection schemes, improved coordination, and safer startup/shutdown sequences. Mechanical design supports easy installation and maintenance: removable terminals and projection mounting simplify field wiring and mounting in crowded switchgear bays. Compatibility with the ETR-4000 base family makes upgrades straightforward for existing Eaton protection systems, reducing training time and preserving familiar configuration workflows. The integrated approach minimizes commissioning risk and accelerates qualification in demanding facilities. Warranty and service policies reinforce risk management: the Eaton one-year warranty from installation or 18 months from shipment provides coverage during early deployment, while Eaton's support ecosystem helps teams troubleshoot integration issues and optimize protection settings.

FAQs

Begin by verifying compatible base hardware and ensure the ETR-4000 foundation is in good condition. Wire the 8 digital inputs and 9 digital outputs to the associated field devices, connect the two current sensing inputs, and mount the unit using the projection mounting method. Use removable terminals for straightforward termination, then perform a staged commissioning including protection settings, communication tests, and SCADA integration.
Key specs include a power supply range of 19-300 Vdc and 40-250 Vac, two current sensing inputs, eight digital inputs, nine digital outputs, and a phase current range of 5A/1A. The unit operates at 50/60 Hz and supports Modbus TCP or DNP3 TCP/UDP communications over LC fiber, enabling reliable industrial networking and remote diagnostics.
Yes. The device is designed as a transformer protection relay with integrated metering and communications, including zone selective interlocking and fiber Ethernet interfaces. Its flexible power inputs and robust I/O enable coordinated protection schemes and easier SCADA integration, making it suitable for both substations and large industrial installations.
The provided data lists 'Compliances: Contact Manufacturer,' so exact certifications should be confirmed with Eaton. In practice, transformer protection relays commonly reference CE markings and suitable enclosure ratings, but always verify current Certification/Compliance documents with the manufacturer before procurement or deployment.
Warranty is one year from the date of installation or eighteen months from shipment, whichever comes first. Eaton’s Selling Policy 25-000 provides guidance on distributor and product support. Ongoing technical support and access to specification sheets, application notes, and software updates are available to assist with configuration, testing, and maintenance.
