FAQs

The ETR-4000-2A3HB0 uses removable terminals and a semi-flush mounting method for straightforward field installation. To integrate with an existing ETR base relay, align the communication and I/O wiring to the 61850, Mbus TCP, or DNP3 TCP/UDP interfaces, secure the terminals, and verify power is within the 19-300 Vdc / 40-250 Vac range. Pre-configured protection logic can be migrated to minimize downtime.
This model provides 8 digital inputs, 9 digital outputs, and 2 current sensing inputs, enabling current protection, metering, and differential protection. It also supports zone selective interlocking with two interlock zones, allowing coordinated tripping. With IRIG-B and other I/O options, you can tailor trip and monitoring functions to transformer protection schemes in substations and OEM equipment.
Yes. The ETR-4000-2A3HB0 communicates over Ethernet using 61850, Mbus TCP, or DNP3 TCP/UDP, enabling seamless integration with SCADA, substation automation, and OEM control systems while reducing wiring complexity and cross-vendor integration challenges.
The relay supports a wide power range of 19-300 Vdc and 40-250 Vac, with a frequency rating of 50/60 Hz. This flexibility simplifies installation across diverse plant environments and minimizes the need for additional power conversion equipment.
