Eaton Specification Sheet - DD324NDKW-00V3
The DD324NDKW-00V3 employs a heavy-duty double-door design to maximize operator access and safety, delivering reliable isolation for machine control panels and process lines. Feature → Business Impact → Application: Line and load voltage indicators provide immediate status feedback, reducing troubleshooting time during commissioning and start-up in manufacturing cells. This improves startup reliability and reduces unplanned downtime when wiring changes are required in automotive, packaging, or material handling lines. Feature → Business Impact → Application: Fusible configuration with neutral enables precise protection for three-phase four-wire systems, meeting Class H fuse requirements while minimizing nuisance trips during peak load scenarios in continuous production. Feature → Business Impact → Application: Painted galvanized steel enclosure with NEMA 12/3R ratings delivers dust-tight and weather-resistant protection, ideal for factory floor installations, electrical rooms, and exterior-rated installations where moisture may be present. Feature → Business Impact → Application: 200 A / 240 V rating and HP range up to 150 hp at higher voltages support scalable automation deployments, reducing inventory variety and simplifying lifecycle maintenance in large motor control centers. Feature → Business Impact → Application: Wire sizes from #6 AWG to 300 kcmil enable flexible conductor routing for feeders and branch circuits, simplifying retrofits and upgrades in legacy plants or new lines without rework. Feature → Business Impact → Application: UL Listed certification provides compliance confidence for safety audits and customer requirements, helping procurement teams meet internal standards and external regulatory expectations. These attributes collectively improve installation speed, reliability, and total cost of ownership for industrial electrical protection and circuit control.
