FAQs

Begin with system de-energization and ensure proper safety procedures. Mount the unit using projection mounting, connect eight digital inputs and nine outputs to relevant control circuits, and wire the two current sensing inputs for protection logic. Establish Ethernet communication via RJ45 for 61850, Mbus TCP, or DNP3 TCP/UDP, and configure the power supply to 19-300 Vdc or 40-250 Vac. Finally, verify protection logic, interlocks, and metering channels in the commissioning stage to confirm correct operation.
Key specs include a power supply range of 19-300 Vdc or 40-250 Vac with 50/60 Hz, 5A and 1A phase currents, 8 digital inputs, 9 digital outputs, and 2 current sensing inputs. Communication supports 61850 or Mbus TCP and DNP3 TCP/UDP over Ethernet RJ45. It also offers zone selective interlocking with two interlocks and differential protection with metering capabilities for transformer protection and monitoring.
Yes. The relay provides transformer protection features suitable for substations, including differential protection, current protection and metering, zone selective interlocking, and multi-protocol Ethernet communications for integration with SCADA and EMS. With its robust I/O (8 inputs, 9 outputs) and flexible power options, it supports reliable protection schemes in harsh substations and industrial environments.
Compliances are listed as Contact Manufacturer, and exact certifications such as SIL, CE, or IP ratings should be confirmed with Eaton. Given Eaton’s broad range of protective relays, regional approvals are typically pursued per installation site requirements. Always request current certification documentation during procurement to ensure regulatory alignment with your facility standards.
The ETR-4000-2A0HA1 enables remote diagnostics, faster fault localization, and reduced downtime, contributing to a favorable return on investment. Its modular I/O and removable terminals simplify maintenance and retrofit projects, while the warranty (one year from installation or 18 months from shipment) provides a predictable support window. Over time, improved asset uptime and streamlined maintenance planning drive lower operating costs.
