FAQs

Begin by mapping the eight digital inputs, two analog inputs, and two analog outputs to your protection logic and metering requirements. Utilize the ETR-4000 base compatibility to replace or upgrade legacy relays without major wiring changes. Leverage zone selective interlocking and trip coil monitoring to coordinate fast fault clearing, while ensuring the Modbus or DNP3 TCP interfaces align with your SCADA network for reliable supervision.
The unit provides eight digital inputs, nine digital outputs, two analog inputs, and two analog outputs. This supports differential, current, voltage, and power protection with embedded metering. In practice, you can implement sequential tripping, alarm signaling, and metered power parameters, delivering richer visibility and faster decision-making in transformer protection schemes.
Yes. The ETR-5000-2B2KA1 supports Modbus and DNP3 TCP over LC duplex fiber optic Ethernet, enabling reliable remote monitoring and control. This integration helps align protection events with SCADA dashboards, supports time-stamped archiving via IRIG-B, and improves coordination across distributed transformer assets.
Yes. The relay includes Zone Selective Interlocking (2) and Trip Coil Monitor capabilities, enabling faster protection coordination and safer, targeted clearance of faults. This is particularly valuable in multi-transformer configurations where selective tripping reduces system disruption and improves reliability.
The product carries Eaton’s standard warranty policy with terms specified by policy 25-000, typically one year from installation or eighteen months from shipment, whichever occurs first. For ongoing maintenance, consult Eaton’s published specification sheets and available training resources, and rely on manufacturer-originated documentation (e.g., the ETR-5000-2B2KA1 datasheet) for service intervals and part recommendations.
