Eaton Specification Sheet - DD365FDKW-00V1
Three-pole, fusible switch design delivers safe, isolated disconnect for heavy machinery, reducing arc-flash exposure and equipment damage while supporting 600 V three-phase systems. The Class H fuse provision enhances selectivity and fault isolation, lowering total downtime and maintenance costs in motor-control applications. The line-side voltage indicator with window provides immediate status visibility, enabling faster fault triage and safer servicing without unnecessary disassembly. Built into a heavy-duty double-door enclosure, the unit resists dust and moisture (NEMA 12, NEMA 3R) in demanding environments, improving uptime in manufacturing, packaging, and material-handling lines. The 400 A rating supports large motors and feeders, while the 72.46 in wide enclosure simplifies integration with existing switchgear footprints and MCCs. Installation benefits include straightforward wiring (three wires), clear labeling, and compatibility with standard 600 V distribution schemes, reducing wiring errors and commissioning time.

FAQs
The DD365FDKW-00V1 is a three-pole, fusible safety switch rated for 600 V and 400 A, making it suitable for 480/600 V three-phase systems. It supports heavy-duty motor loads and provides a safe, isolated disconnect with Class H fusing. When integrating with existing MCCs or control panels, confirm conductor sizes and panel clearance to ensure compliant, reliable operation.
Important specs include amperage rating of 400 A, voltage rating of 600 V, three-pole configuration, fusible without neutral, Class H fuse provision, and UL Listed certification. enclosure rating is NEMA 12/3R with painted galvanized steel construction. Dimensions are approximately 16.41 in depth, 24.32 in height, and 72.46 in width, with a weight of 219 lb.
Yes. The enclosure is rated NEMA 12 and NEMA 3R, designed to resist dust intrusion and moisture ingress in industrial settings. This makes the device appropriate for factory floors, wash-down zones, and outdoor-rated installations where environmental exposure is a concern, while maintaining safe isolation performance.
Plan for proper mounting clearance and planed wiring routes to accommodate a 72.46 in wide, heavy enclosure. Use the line-side voltage indicator with window for quick status checks and minimize downtime during servicing. Ensure lockout/tagout procedures are in place and verify that conductors match the 3-wire, three-pole configuration for safe, code-compliant operation.
The DD365FDKW-00V1 is backed by Eaton’s policy with a one-year warranty from installation or eighteen months from shipment, whichever occurs first. For ongoing reliability, follow the recommended maintenance schedule, replace Class H fuses as specified, and utilize Eaton’s specification sheet and technical resources for compliance and lifecycle planning.
