FAQs
Begin with standard mounting on a compatible panel and use the removable terminals to simplify wiring. Connect the 8 digital inputs and 6 digital outputs per your protection scheme, and set the supply to 19-300 Vdc or 40-250 Vac as required. Verify RS485/RS-232 interfaces for Modbus RTU and DNP3.0 RTU, and confirm operating temperature range of -20°C to 60°C during commissioning.
Key specs include 8 digital inputs, 6 digital outputs, 1 current sensing input, 5 A contact rating, burden 10 W / 17 VA, power supply range 19-300 Vdc or 40-250 Vac, frequency 50/60 Hz, and operating temp -20°C to 60°C. The device is designed for feeder protection with standard mounting and removable terminals for easy wiring.
Yes. The relay is purpose-built for feeder protection with a bus differential topology, supports Modbus RTU and DNP3.0 RTU communications for integration with PLC/SCADA, and offers a rugged build with conformal coating. Its standard mounting and removable terminals simplify installation in control cabinets, while its wide supply range supports diverse substation architectures.
Compliances are listed as 'Contact Manufacturer' for this product, meaning regional certifications should be confirmed with Eaton during procurement. When planning installations, verify regional safety and electrical standards (for example protective relays in industrial environments often require CE or other regional marks) and ensure compatibility with your control system and network protocols.
Expect lower downtime thanks to fast fault isolation and reliable differential protection. The device carries a one-year warranty from installation or 18 months from shipment, whichever comes first, and its low burden (10 W / 17 VA) reduces energy impact. Remote communication via Modbus RTU and DNP3.0 RTU supports proactive monitoring, enabling preventive maintenance and potential cost savings over time.
