Quick Summary

Eaton transformer relay is a compact protection device designed for transformer protection in industrial power systems. Engineers often struggle with protecting transformers across wide input ranges while maintaining reliable remote monitoring and integration with SCADA. While specific certifications vary by region, industries commonly expect CE marking, IP-rated enclosures, and SIL-ready features for transformer protection relays. This model delivers Modbus RTU or DNP3 RTU communications over fiber, 8 digital inputs and 9 digital outputs, and a 19-300 Vdc / 40-250 Vac power supply range, enabling robust data capture and fast fault isolation. The combination of industrial-grade hardware and Eaton's warranty supports higher uptime and easier procurement through familiar specification language.

8 digital inputs and 9 digital outputs plus 2 current sensing inputs provide flexible wiring and scalable control for transformer protection, reducing panel complexity and installation time. Business impact: streamlined cabinet wiring, faster commissioning, and clearer fault diagnostics in substations and equipment rooms. Application: suitable for protection schemes that require reliable I/O expansion and metering alongside control functions. The power supply range of 19-300 Vdc and 40-250 Vac at 50/60 Hz supports diverse plant mains, enabling a single device to cover multiple feeders without extra power supplies. Business impact: lowers inventory and maintenance costs while improving uptime. Application: ideal for retrofit projects and new builds with mixed voltage environments. Communication options include Modbus RTU or DNP3 RTU over fiber optic ST, plus IRIG-B and URTD interfaces, simplifying integration with existing SCADA, PMUs, and protective relays. Business impact: improved remote diagnostics, faster fault localization, and enhanced data integrity. Application: critical infrastructure where wire-length and EMI considerations matter. Protection capabilities cover current, voltage, power, and differential protection with 2-zone selective interlocking and Trip Coil Monitor, delivering precise fault isolation and reduced backfeed risk. Business impact: higher selectivity, minimized outage scope, and better asset protection. Application: transformer banks and switchyard equipment needing coordinated trip schemes. Mechanical and installation advantages include removable terminals and projection mounting, providing straightforward field wiring and secure panel mounting. Business impact: lower installation time and cleaner panel layouts. Application: retrofits or new assemblies in control cabinets. Compatibility with the base ETR-4000 relay enables phased upgrades and common maintenance practices, while the built-in 8/9 I/O configuration supports scalable protection architectures. Warranty and support: Eaton’s policy (one year from installation or eighteen months from shipment) offers predictable coverage and access to service resources, reducing risk during deployment.

FAQs

The device features removable terminals and projection mounting for straightforward field wiring and secure panel installation. With 8 digital inputs and 9 outputs, plus compatibility with the ETR-4000 base relay, you can scale protection without rewiring. Plan for fiber optic communications if you need Modbus RTU or DNP3 RTU over fiber, and allocate space for URTD/IRIG-B interfaces as required by your control strategy.
Key specs include a power supply range of 19-300 Vdc or 40-250 Vac and a frequency rating of 50/60 Hz. It supports 5A and 1A phase current options, 8 digital inputs, 9 digital outputs, and 2 current sensing inputs. Communication is available via Modbus RTU or DNP3 RTU over fiber, with additional interface options for precision timing and remote monitoring.
Yes. It provides comprehensive protection types—current, voltage, power, and differential protection—with Zone Selective Interlocking (2), a Trip Coil Monitor, and IRIG-B/URTD interfaces for synchronized control. These features support fast fault isolation and coordinated protection critical for substations and high-reliability environments.
Compliance details are published by Eaton; typical deployments expect standard industrial certifications and regional markings. Verify CE marking, IP-rated enclosure suitability, and SIL readiness with Eaton’s specification sheets and local distributors to ensure alignment with your regulatory requirements.
The unit’s reliable protection, remote communication options, and modular I/O reduce wiring, commissioning time, and downtime. A one-year warranty (or 18 months from shipment) provides asset confidence, while compatibility with existing Eaton relays (ETR-4000) supports phased upgrades, lowering long-term maintenance costs.
