The ETR-5000-2A2LA0 features removable terminals and semi-flush mounting, enabling faster field installation and easier retrofits in tight panels; this reduces commissioning time and wiring costs while improving reliability. With eight digital inputs and nine outputs plus diverse I/O options such as Trip Coil Monitor, Sensitive Ground Input, URTD Interface, and IRIG-B, operators gain granular control and precise protection coordination, lowering risk and improving fault containment. The power supply range of 19-300 Vdc and 40-250 Vac, combined with 50/60 Hz compatibility, supports operation across geographies and varying electrical systems, reducing spare parts and stocking requirements. Mbus TCP or DNP3 over LC duplex fiber enables robust SCADA integration, enabling proactive maintenance, remote diagnostics, and centralized fault analytics. Zone selective interlocking (2) further enhances selective tripping, delivering faster restoration and reduced outage impact for utilities and OEMs. Overall, the solution offers a scalable path to digital transformer protection, improving compliance, efficiency, and total cost of ownership.

FAQs

Plan for removable terminals and semi-flush mounting to simplify field wiring and maintenance. The device supports standard transformer protection architectures with eight digital inputs and nine outputs, enabling straightforward panel integration and easy retrofits. Ensure power supply compatibility within the 19-300 Vdc / 40-250 Vac range and verify network cabling for Mbus TCP or DNP3 over LC fiber.
It provides differential protection, current protection and metering, power protection and metering, and voltage protection and metering through sensing inputs. With 2 current sensing inputs and 8 digital inputs, you can configure precise protection schemes and metering across multiple transformer assets, supported by Zone Selective Interlocking for coordinated tripping and minimized outage impact.
The relay supports Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet, enabling reliable, low-latency data exchange with SCADA and OT networks. This makes remote monitoring, diagnostics, and asset health trending feasible across dispersed substations and industrial facilities, reducing现场现场现场 downtime and enabling proactive maintenance scheduling.
Key resources include the Eaton specification sheet for the ETR-5000-2A2LA0 and brochures on E-Series protective relays. The downloads section also offers multimedia content on interfacing with E-Series Relays and a range of datasheets. Use these documents to guide wiring, configuration, and integration with power management and monitoring systems.
Warranty is governed by Eaton's policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. For compliance questions, configurator support, or regional certification details (CE, SIL, IP), contact Eaton directly or your authorized distributor to confirm applicable terms and service options.
