FAQs

Begin by confirming panel clearance and mounting the relay with semi-flush support. Use the removable terminals to connect 8 digital inputs, 9 digital outputs, 2 analog inputs, and 2 analog outputs. Connect the RS-485 communication lines for Modbus RTU or DNP3 RTU, wire the protective grounds as applicable, and supply power within the 19-300 VDC / 40-250 VAC range. After wiring, use the front panel or software to configure protection parameters and I/O logic.
The ETR-5000-2B2BA0 supports Modbus RTU or DNP3 RTU over RS-485. Start by wiring the RS-485 pair to the controller network, assign a unique Modbus or DNP3 address, and set baud rate, parity, and stop bits per your system. Use Eaton’s configuration tools or the front panel to map inputs/outputs to protection functions, alarms, and metering signals, enabling scalable integration with SCADA and PLCs.
Yes. The relay is designed for 50/60 Hz operation and accepts a broad power range of 19-300 VDC or 40-250 VAC. This makes it compatible with global transformer protection schemes and allows seamless retrofits in existing 3-phase and single-phase transformer panels without major power-system changes.
The relay supports differential protection and voltage/current protection with metering capabilities, along with zone selective interlocking (2). It provides robust transformer protection, remote diagnostics via RS-485 networks, and flexible I/O for signaling and interlocks. It’s well-suited for substations, switchgear, and plant distribution panels requiring fast fault isolation and reliable monitoring.
Eaton offers a warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. For technical support, calibration, and service options, contact Eaton's support channels or a certified Eaton distributor. This ensures access to firmware updates, documentation, and field service if needed.
