FAQs

Plan mounting on a semi-flush surface and use the removable terminals to simplify wiring. Connect eight digital inputs and nine outputs according to your protection scheme, then power the unit from 19-300 Vdc or 40-250 Vac. Configure Ethernet communications for 61850, Mbus TCP, or DNP3 TCP/UDP over Enet RJ45. Label all signals clearly and verify proper grounding to ensure reliable protection and signaling during commissioning.
The relay supports 19-300 Vdc and 40-250 Vac power with 50/60 Hz operation, eight digital inputs, nine digital outputs, and two current sensing inputs. It provides 61850, Mbus TCP, and DNP3 TCP/UDP networking over Ethernet, and supports I/O options such as Trip Coil Monitor and IRIG-B. With 5A/1A phase current options, you can tailor protection logic for transformer feeders while maintaining compatibility with existing control infrastructure.
Yes, the ETR-4000-2A1HB0 is designed for transformer protection with current protection and metering, differential protection capabilities, and zone selective interlocking.
