High impedance protection delivers selective fault clearance, reducing nuisance trips and preserving system uptime while enabling precise isolation of faults on power buses. Business impact: lower maintenance costs and fewer unscheduled outages in critical distribution networks; application: main bus protection in switchgear and substations. MODBUS/DNP3 (FO ST) interface enables seamless SCADA integration, accelerating commissioning and reducing wiring complexity. Business impact: faster fault data acquisition and easier remote diagnostics; application: modern substation automation and remote monitoring. Conformal coating extends reliability in harsh environments, lowering field repair requirements; application: outdoor or damp locations with reduced corrosion risk. Weight, dimensions, and mounting: projection panel mounting simplifies retrofit into existing enclosures, saving labor and enabling quicker deployments. Business impact: shorter project timelines and lower installation risk; application: retrofit projects and new builds with space constraints. Burden is 10 W / 17 VA and contact rating is 5 A ac/dc, supporting robust signaling without excessive power draw. This combination delivers dependable performance in a compact footprint. Warranty aligns with Eaton policy, offering protection during installation or shipment windows. Application context: critical protection roles where reliability and long-term maintenance costs matter.

FAQs
This relay supports projection panel mounting, which simplifies retrofits and new panel installations. Ensure space for the 7.49 in length, 8.62 in height, and 6.82 in width, and plan for the 5 A contact rating and 10 W / 17 VA burden. Verify power supply, wiring, and MODBUS/DNP3 connections prior to commissioning.
High impedance protection increases selectivity by discriminating faults on the bus from external disturbances, reducing nuisance trips. By combining this with a 5 A contact rating and a controlled burden, the system maintains protective reliability while minimizing unnecessary disruptions, improving uptime and extending equipment life in distribution networks.
Yes. The relay includes MODBUS/DNP3 (FO ST) interfaces, enabling straightforward integration with typical SCADA and automation systems. When planning deployment, ensure compatible network addressing, communication settings, and appropriate protection zones to maximize data visibility and rapid fault management.
The provided data lists Compliances as Contact Manufacturer, with suggested regional validation to be provided by Eaton. For CE, SIL, or IP-related ratings, contact Eaton to confirm applicable certifications for your installation site and regulatory requirements.
Fast fault isolation reduces outage duration and minimizes collateral damage, improving reliability and uptime. Conformal coating enhances environmental resilience, lowering field maintenance. The 1-year warranty (or 18 months from shipment) provides initial protection, and the robust 5 A contact rating supports long-term service with limited replacement needs.
