Eaton Specification Sheet - DD327FDKW-00V2
Enclosure durability translates directly to reduced maintenance costs in dusty or moist factory environments. The NEMA 12/3R enclosure, paired with painted galvanized steel construction, provides dust-tight and corrosion-resistant protection essential for long-term reliability. The 800 A amperage rating and 240 V operation support demanding motor-control applications, enabling reliable disconnection for large pumps, conveyors, and presses with minimal interruption to production. Three-pole, three-wire configuration with Fusible without neutral offers flexible protection schemes for industrial feeders while minimizing neutral conductor complexity. The integrated load-side voltage indicator with window delivers immediate status visibility without door openings, increasing maintenance safety and uptime. UL Listed certification simplifies audits and aligns with harsh-duty electrical protection standards, while Class L fuse provision ensures precise protection against short-circuit and arc events. Compatibility with a wide range of feeders up to 750 kcmil facilitates scalable upgrades and retrofit projects, reducing total cost of ownership for OEMs and facilities.
