FAQs

Begin with verifying supply compatibility (19-300 Vdc; 40-250 Vac) and confirm 50/60 Hz operation. The device uses removable terminals and a projection mounting method, which simplifies conduit routing and field wiring. Plan for fiber optic wiring to support Modbus RTU or DNP3 RTU communication, and map the 8 digital inputs and 9 digital outputs to your control scheme to ensure quick, safe integration.
Yes, the unit supports Modbus RTU or DNP3 RTU over fiber optic ST, which provides EMI immunity and secure data transfer. This facilitates reliable remote monitoring, event logging, and faster fault diagnosis when connected to SCADA systems, reducing diagnostic time and improving overall system availability.
The relay includes Current Protection and Metering, Differential Protection, and Zone Selective Interlocking (2). These features enhance fault detection accuracy, enable selective isolation of faults, and provide precise metering for energy auditing, ultimately reducing downtime and damage to equipment in transformer protection scenarios.
The datasheet lists Compliances as 'Contact Manufacturer,' so public certifications like SIL, CE, or IP ratings are not specified here. For regulatory approvals, confirm with Eaton or review the latest datasheet to ensure compliance with your regional requirements and safety standards.
Warranty follows Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever comes first. Regular maintenance should focus on verifying fiber communication integrity, testing digital I/O, and confirming protection logic settings after any system changes to sustain protection efficacy and minimize unplanned downtime.
