Quick Summary

The Eaton transformer relay ETR-5000-2A2BB0 provides digital protection for transformers and feeder circuits. Engineers often struggle with fast fault isolation and reliable interlocks across protection schemes, especially in evolving substation layouts. Compliance details should be confirmed with Eaton, as the product lists 'Compliances: Contact Manufacturer'; verify any CE, SIL or IP requirements for your installation. In addition, this unit's Modbus RTU or DNP3 RTU over RS-485 enables seamless SCADA integration, while the wide power supply range (19-300 Vdc / 40-250 Vac) supports diverse field conditions and simplifies procurement. The result is reduced downtime, improved interoperability, and clearer visibility across protection and metering functions for your power distribution assets.

Feature → Business Impact → Application: Flexible power supply range lets you deploy the relay across a broad set of substations without rewiring power rails, reducing installation costs and spare parts stock while enabling consistent protection settings for 19-300 Vdc and 40-250 Vac systems. This supports rapid deployment in mixed-voltage environments and simplifies cataloging for procurement teams. Feature → Business Impact → Application: 8 digital inputs and 9 digital outputs plus 2 current sensing inputs enable comprehensive protection logic and trip coordination, improving response times and reducing nuisance trips in transformer banks. Application includes zone selective interlocking (2) and synchronized trips in industrial facilities. Feature → Business Impact → Application: Modbus RTU or DNP3 RTU over RS-485 provides easy SCADA integration, enabling centralized monitoring, event logging, and remote diagnostics, which lowers field-service visits and accelerates maintenance planning. Feature → Business Impact → Application: Conformal coating on circuit boards and removable terminals with semi-flush mounting deliver reliable performance in harsh environments and simplify field upgrades, installation checks, and terminal reconfigurations. Feature → Business Impact → Application: Wide terminal options and the ETR-4000 base compatibility ensure a smooth upgrade path from legacy relays, reducing commissioning risk and preserving existing protection schemes.

FAQs

Installers should plan for removable terminals and semi-flush mounting to simplify field wiring and future upgrades. Ensure supply rails match the 19-300Vdc and 40-250Vac ranges and verify RS-485 wiring for Modbus RTU or DNP3 RTU communication. The device supports 8 digital inputs, 9 outputs, and 2 current sensing inputs, which informs I/O terminal layout and protection logic sequencing.
RS-485 enables Modbus RTU or DNP3 RTU communication, allowing the ETR-5000-2A2BB0 to exchange real-time protection data, events, and metering information with SCADA systems. This reduces manual data gathering, enhances fault analysis, and supports remote diagnostics and coordinated protection across transformers and feeders.
Yes. As a transformer protection relay with 8 inputs, 9 outputs, and 2 current sensing inputs, it is designed for transformer protection schemes, including trip coordination and interlocking. Its compatibility with the ETR-4000 base, 50/60 Hz operation, and RS-485 communications make it a viable upgrade for substations and plant protections.
Certification status should be confirmed directly with Eaton. The product listing indicates Compliances: Contact Manufacturer, so confirm CE, SIL safety considerations, IP ratings, and any regional regulatory requirements for your installation to ensure full compliance.
The ETR-5000-2A2BB0 offers a one-year warranty from installation or 18 months from shipment, whichever comes first, plus conformal coating for environmental durability. By enabling remote SCADA visibility, reducing field service visits, and improving fault isolation, it can lower maintenance costs and improve transformer uptime and asset ROI.
