125A amperage rating and a three-pole design provide coordinated protection for three-phase busways, reducing trip inconsistencies and downtime. This aligns with FD/F Frame families, enabling straightforward replacements and minimizing spare parts inventory. Application: busway networks in manufacturing and process facilities needing reliable plug-in protection. High interrupt ratings of 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac allow protection in high fault-current environments, improving safety margins and reducing damage risk to downstream equipment. Application: industrial plants with diverse voltage profiles. Grounding options of 50% integral or housing grounding offer installation flexibility and safety compliance, simplifying the wiring arrangement during installation. Certifications including ANSI/IEEE, CSA, UL 857, and NEMA compliance support procurement with confidence. Weight is approximately 25 lb, supporting manageable on-site handling and quicker replacements. Warranty remains Eaton’s standard policy (1 year from installation or 18 months from shipment) to minimize lifecycle risk.
