Power supply flexibility lets you install the relay across diverse sites. With a power range of 19-300 Vdc and 40-250 Vac, the device tolerates voltage variations, reducing wire conversion costs and speeding commissioning on multi-site projects. This capability minimizes risk from supply swings and simplifies design validation during system integration. High I/O count and removable terminals streamline wiring, testing, and maintenance. Eight digital inputs and nine outputs support complex protection logic and alarm signaling while enabling quick field upgrades without panel redesigns. The conformal coating protects boards in harsh environments, extending service life in dusty or humid facilities. Protection and monitoring features deliver targeted reliability. Two current sensing inputs support current protection and metering, while Trip Coil Monitor and Zone Selective Interlocking enhance selective tripping and fast fault isolation. These capabilities reduce unplanned outages and improve safety margins for feeders and transformers in critical infrastructures. Communications and system integration are straightforward. Modbus and DNP3 TCP over LC duplex fiber optic Ethernet enable remote monitoring and seamless integration with PLCs and SCADA. URTD interface and IRIG-B options provide time synchronization and alternate interfaces for specialized control rooms, easing configuration across utilities and OEM deployments. Field readiness and maintenance efficiency come from modular design. Removable terminals allow hot-swapping and simplified diagnostics, while the semi-flush mounting supports compact control panels. The base ETR-4000 family compatibility helps standardize settings and reduces training time for teams already familiar with Eaton protection relays. Overall, the ETR-4000-2A1KB0 delivers measurable ROI through reduced downtime, faster fault localization, and lower spare parts inventory. The combination of protection, metering, and communications in a single unit is ideal for industrial plants, data centers, and energy infrastructure seeking reliable transformer protection with scalable diagnostics.
