FAQs
The DD324NDKW-00V2 is designed for three-pole, four-wire circuits and supports #6 AWG through 300 kcmil conductors. It fits standard industrial enclosures and is compatible with NEMA 12 and NEMA 3R environments. This combination simplifies retrofits by aligning with common panel layouts, reducing enclosure modification time and enabling straightforward wiring schemes for OEM and retrofit projects.
Key specs include a 200A amperage rating, 240V voltage rating, and fusible with neutral configuration. It is a three-pole, four-wire switch designed for heavy-duty protection. The device also features a load-side voltage indicator and a window for quick status checks, improving fault diagnosis and maintenance planning in motor and process applications.
Yes. The enclosure supports NEMA 12 and NEMA 3R ratings and is constructed from painted galvanized steel. This combination provides dust-tight protection and rain/ice exposure resistance, making it suitable for demanding industrial floors, outdoor bays, and washdown-adjacent areas found in manufacturing and material handling facilities.
The product follows Eaton’s warranty policy, typically one year from installation or eighteen months from shipment, whichever occurs first, ensuring protection against manufacturing defects. Routine maintenance includes periodic inspection of fuses, verification of load-side indicators, and checking enclosure integrity to maintain UL-listed safety performance and fault visibility.
By combining a robust 200A rating with a clear load-side indicator and durable NEMA 12/3R enclosure, the DD324NDKW-00V2 reduces commissioning time, speeds fault location, and minimizes unplanned outages. The ability to wire up to large conductors (#6 AWG–300 kcmil) also supports future expansion without new switchgear, delivering long-term cost savings in service and maintenance.
