Quick Summary

The Eaton transformer relay ETR-5000-2A3LA0 provides transformer protection for industrial power systems. Engineers seeking reliable protection across multiple feeders often face coordination gaps, miswiring, and limited visibility into protective actions. Compliance details are listed as 'Compliances: Contact Manufacturer'; this note highlights the need to request current certifications and installation guidance. This device supports remote monitoring via Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet and offers 50/60 Hz operation with 19-300 Vdc or 40-250 Vac power. By consolidating protection, metering, and communications in a single chassis, it reduces panel complexity and accelerates commissioning, while enabling interoperability with modern SCADA and OT networks. For engineers, this translates to faster fault isolation, easier maintenance planning, and improved uptime in substations and plant-level power distribution. Its robust IO and time synchronization options support precise protective schemes for critical loads.

FAQs

When installing the ETR-5000-2A3LA0, plan for semi-flush mounting and removable terminals to simplify field wiring. Ensure the unit is housed in a compliant enclosure with adequate clearance for cooling and access to 19-300 Vdc or 40-250 Vac power, plus connections for 8 digital inputs and 9 digital outputs. Reference Eaton wiring diagrams and the ETR-5000-2A3LA0 specification sheet during commissioning.
The relay provides 8 digital inputs, 9 digital outputs, and 2 current-sensing inputs, powered from 19-300 Vdc or 40-250 Vac with 50/60 Hz operation. It supports Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet for SCADA integration, plus optional Zone Selective Interlocking and IRIG-B timing interfaces, enabling robust remote monitoring and coordinated protection.
Yes. The ETR-5000-2A3LA0 is designed for transformer protection and metering, offering differential, power, voltage, and current protection with integrated metering. Its flexible IO and secure communications with SCADA interfaces make it suitable for substations and plant-level transformer protection schemes, enabling fast fault isolation and accurate monitoring of transformer health.
Compliance details are listed as 'Compliances: Contact Manufacturer' on the datasheet. For formal certifications such as CE, SIL, or IP ratings, consult Eaton’s specification sheet (ETR-5000-2A3LA0) or contact Eaton directly to obtain the current, site-specific certification documentation and installation guidance.
Consolidating protection, metering, and communications into a single unit reduces panel count and wiring complexity, shortening commissioning time and lowering installation costs. Improved protection coordination minimizes downtime, while the device’s remote communication capabilities enable proactive maintenance. The warranty guidance aligns with Eaton policy (one year from installation or 18 months from shipment), supporting predictable lifecycle budgeting.
