FAQs

Begin by confirming the ETR-4000 as the base relay and ensure the new unit is physically compatible for projection mounting. Remove and re-seat removable terminals as needed, then connect the eight digital inputs and nine outputs according to the control schematic. Verify power connections within the 19–300 Vdc / 40–250 Vac range and test the protective logic offline before energizing the system. This approach minimizes commissioning time and reduces the risk of mis-wiring during a retrofit.
Confirm power supply range (19–300 Vdc or 40–250 Vac) and frequency rating (50/60 Hz). Validate eight digital inputs and nine digital outputs, plus two analog inputs and two analog outputs for metering and protection signals. Ensure the phase current options (5 A and 1 A) align with your CT configurations and that the module supports the IRIG-B, Trip Coil Monitor, and Sensitive Ground Input options required by your protection scheme.
Yes. The ETR-5000-2B1KA1 supports Modbus / DNP3 TCP communications over LC duplex fiber, enabling reliable integration with SCADA and historian systems. This facilitates remote monitoring, event analysis, and coordinated protection across distributed assets, which is essential for large factories and substations that require centralized visibility.
Compliance details are not listed in the provided data; please contact the manufacturer to confirm certifications applicable to your region and use case. In practice, transformer protection relays commonly align with industry standards, so verify CE, SIL, IP ratings, or other relevant approvals with Eaton prior to procurement.
By consolidating protection, metering, and communication into a single transformer relay, you reduce hardware footprint, simplify wiring, and accelerate commissioning. The expanded I/O, remote communication, and diagnostic capabilities support predictive maintenance, lowering unplanned outages and extending transformer life. Retrofit projects benefit from backward compatibility with the ETR-4000 base while enabling modern monitoring and integration with existing SCADA systems.
