Feature: Eight digital inputs and nine digital outputs provide flexible protection logic and signaling, enabling tailored transformer protection schemes. Benefit: Reduces wiring complexity and speeds up commissioning, lowering both install time and field errors in switchgear assemblies. Application: Ideal for transformer protection relays in substations and industrial plants seeking reliable fault signaling and scalable I/O. Feature: Two current-sensing inputs and selectable phase current options (5A and 1A) allow compatibility with common CT configurations, improving flexibility when migrating from legacy relays. Benefit: Enables accurate protection thresholds and metering without re-wiring CT networks. Application: Retrofit projects and greenfield installations where CT compatibility matters. Feature: Wide power-supply range (19–300 Vdc, 40–250 Vac) and 50/60 Hz operation simplify integration into diverse plant electrical systems, reducing spare parts stock and compatibility concerns. Benefit: Streamlined procurement and faster deployment in mixed voltage environments. Application: Mixed-voltage plants, OEM equipment, and retrofits. Feature: Ethernet-based communications (61850 or Mbus TCP or DNP3 TCP/UDP over Enet RJ45) supports modern substation automation and remote monitoring. Benefit: Improves interoperability, enables centralized diagnostics, and shortens mean time to repair. Application: Industrial automation networks, substations, and data-center protection schemes. Feature: I/O options such as Sensitive Ground Input, URTD Interface, Trip Coil Monitor, and IRIG-B enhance protection reliability and time synchronization. Benefit: Reduces nuisance trips, improves fault localization, and aligns with comprehensive protection architectures. Application: Critical transformer protection in mission-critical facilities. Feature: Removable terminals and semi-flush mounting simplify installation and field maintenance. Benefit: Faster maintenance, safer wiring, and easier panel layout in new builds or upgrades. Application: Panel builders and field service teams targeting efficient commissioning and servicing.

FAQs

Installation begins with confirming the panel's supply voltage, then mounting the relay on a semi-flush bracket and connecting the eight digital inputs and nine outputs to your protection scheme. Use removable terminals for quick wiring changes, and verify polarity and CT connections for accurate protection thresholds. Refer to the Eaton specification sheet for any application-specific wiring diagrams and confirm commission testing using the 50/60 Hz power input and the supported Ethernet communications.
Key specs include eight digital inputs, nine digital outputs, two current sensing inputs, and support for 5A and 1A phase currents. It operates on a power supply range of 19-300 Vdc or 40-250 Vac at 50/60 Hz. The device communicates over Ethernet using 61850, Mbus TCP, or DNP3 TCP/UDP. This combination enables integrated protection, metering, and remote diagnostics across modern automation networks.
The ETR-4000-2A1HA0 is designed for transformer protection across industrial and substation environments. Its 8/9 I/O configuration, multi-protocol Ethernet communications, and flexible power options make it adaptable for both field-installed substations and OEM equipment in industrial plants, with the ability to meet diverse protection schemes while maintaining interoperability with existing assets.
Compliance details for the ETR-4000-2A1HA0 are region- and model-specific. The manufacturer lists Compliances as 'Contact Manufacturer,' so it’s important to consult Eaton’s specification sheet and request regional CE, SIL, and IP rating information through Eaton support or an authorized distributor prior to procurement and deployment.
ROI comes from reduced downtime, faster fault isolation, and lower field wiring complexity thanks to the integrated I/O and Ethernet communications. The device carries a standard warranty per Eaton policy (25-000), with coverage for one year from installation or 18 months from shipment. Regular firmware updates and access to Eaton’s documentation support long-term reliability and lower lifecycle costs.
