FAQs

Installation starts with confirming the power supply and communication interfaces. The unit uses removable terminals and supports projection mounting for flexible panel fit. It offers 8 digital inputs and 9 digital outputs, plus a 19-300 VDC / 40-250 VAC power range and fiber optic Modbus RTU or DNP3 RTU communications. Plan for space around the relay and ensure compatible fiber ST connectors for reliable data transfer.
Key specs include a wide power supply range (19-300 VDC, 40-250 VAC), 50/60 Hz operation, and current sensing inputs of 5 A and 1 A. With 8 inputs and 9 outputs, along with Modbus RTU or DNP3 RTU over fiber, the relay supports comprehensive protection schemes (power, differential, voltage) and metering. These capabilities translate to faster fault detection, accurate metering, and reliable signaling for protection coordination.
This relay excels in transformer bank protection, substation transformers, and critical plant transformers requiring remote monitoring. Its firmware supports multiple protection layers, 8/9 I/O, zone selective interlocking, and fiber-based Modbus/DNP3 communications, enabling selective tripping and minimized outage impact in complex protection schemes across utility and industrial environments.
The product documentation lists compliances as 'Contact Manufacturer,' so verify current certifications with Eaton before purchase. For many protective relays in this class, you should confirm safety certifications (such as CE/UL) and enclosure protections (IP ratings) relevant to your region and application. Always request the latest certificate pack to ensure compliance with your installation standards.
Maintenance benefits include remote diagnostics via Modbus RTU or DNP3 RTU over fiber, extensive metering, and differential/voltage protection that simplify fault analysis. The rugged design with removable terminals and robust protection features reduces downtime, while the one-year warranty (18 months from shipment) provides a clear lifecycle protection baseline. Expect improved uptime, faster fault isolation, and lower total cost of ownership.
