FAQs
Plan for removable terminals and semi-flush mounting to ease field wiring and service. Ensure power is supplied within 19-300 Vdc or 40-250 Vac and that the installation space accommodates eight digital inputs, nine outputs, and the available I/O options such as IRIG-B and Trip Coil Monitor. Refer to the datasheet for wiring diagrams and recommended clearances.
The unit offers multi-parameter sensing (current, differential, voltage, and metering) plus Zone Selective Interlocking, enabling fast, selective fault isolation. Its Modbus/DNP3 Ethernet interface supports remote monitoring, while conformal coating and a robust physical design enhance reliability in harsh environments—leading to fewer nuisance trips and lower maintenance costs.
Compliances are specified by Eaton and documented in the official datasheet and regional approvals. For exact certifications (CE, UL, IP ratings) and regional applicability, consult Eaton’s product page or the ETR-5000-2A3KB0 datasheet and confirm with the manufacturer before deployment.
By reducing unplanned downtime and accelerating fault diagnosis, the ETR-5000-2A3KB0 lowers maintenance costs and improves asset availability. Features such as removable terminals, extensive I/O, and remote communication enable faster commissioning, easier troubleshooting, and tighter protection coordination across multiple transformer assets.
