FAQs
The DD324FDKW is a three-pole, fusible safety switch designed for three-wire circuits. It supports wiring from #6 AWG up to 300 kcmil and a 200 A rating. When wiring, connect the three live conductors to the three load terminals and ensure the fuse links are Class H as specified. Lockout/tagout procedures are recommended during installation, and the cabinet should be mounted in a clean, accessible space with proper clearance around the enclosure.
The unit is rated for 200 A and supports up to 150 hp for three-phase loads at 480 V or 600 V. A 50 hp or 125 hp rating is possible under reduced voltage conditions per the documented HP ratings. This makes the switch suitable for larger motors and feeders without requiring oversized protective devices, aiding in coordinated protection and space optimization.
Ideal for power distribution and control panels in manufacturing, material handling, packaging lines, and process industries. Its NEMA 12/3R enclosure provides dust-tight and weather-resistant protection for indoor and protected outdoor areas, while the fusible design with Class H fuses supports reliable motor protection and safe isolation during maintenance.
The DD324FDKW carries UL Listed certification, with a NEMA 12/3R enclosure designation, guaranteeing environmental protection and electrical safety standards compliance. The Class H fuse provision supports standardized motor protection, and the enclosure’s materials (painted galvanized steel) contribute to durability in industrial environments.
Eaton provides a warranty policy (one year from installation or eighteen months from shipment). This, combined with UL certification and robust enclosure protection, translates to lower maintenance costs and reduced downtime. Reliability and spare-part availability from a trusted brand further improve ROI for OEMs and integrators.
