FAQs

Yes. The ETR-4000-2A3GA1 uses removable terminals and a projection mounting method, enabling straightforward retrofits into standard control cabinets. It provides eight digital inputs and nine outputs and communicates via RS-485 Modbus RTU or DNP3 RTU, minimizing re-wiring and simplifying integration with existing Eaton protection schemes and SCADA systems.
Key specs include eight digital inputs, nine outputs, two current sensing inputs, 50/60 Hz operation, power supply ranges of 19–300 Vdc or 40–250 Vac, and Modbus RTU or DNP3 RTU over RS-485. It supports differential and current protection with metering, plus zone selective interlocking, enabling precise fault discrimination and faster restoration in transformer protection schemes.
Yes. The ETR-4000-2A3GA1 includes Modbus RTU and DNP3 RTU over RS-485 communication. This enables direct integration with existing SCADA, historians, and asset management systems, facilitating remote monitoring, alarms, and coordinated protection across a plant network.
Expect reduced wiring and panel space from consolidated I/O, faster installation with removable terminals, and fewer nuisance trips due to improved protection discrimination. Remote diagnostics via Modbus/DNP3 shorten site visits, while the integrated metering supports better energy management and maintenance planning, delivering material and labor cost savings over the device’s lifecycle.
