FAQs
DD324NDKW-00V1 is a 200 A three-pole, four-wire fused safety switch rated for 240 V. It uses a fusible with neutral configuration and is housed in a NEMA 12 / NEMA 3R enclosure. Physical footprint: depth 49.9 in, height 11.62 in, width 17.18 in, and weight 85 lb. Wire size range is #6 AWG to 300 kcmil.
The connector is rated for 240 V nominal operation, with an HP rating listed as up to 150 hp at 1/3 ph for 480/600 V in certain configurations. For standard 600 V service, verify that the application aligns with the specific HP and voltage ratings and consult Eaton’s datasheet to confirm suitable operating conditions.
This model is UL Listed and features a heavy-duty NEMA 12 / NEMA 3R enclosure for dust and moisture protection. It uses a Class H fuse and provides a three-pole, four-wire configuration with line-side voltage indication, supporting safe and compliant isolation in industrial settings.
The built-in line-side voltage indicator with a window allows immediate visual confirmation of live status before servicing, reducing test time and lowering the risk of accidental energization. This is especially valuable during routine maintenance, lockout/tagout procedures, and quick fault isolation in control panels.
Plan for a 49.9 in deep, 17.18 in wide, 11.62 in tall cabinet footprint that weighs 85 lb. It supports 3-pole, 4-wire wiring with #6 AWG–300 kcmil conductors and a fusible with neutral configuration. Ensure panel space accommodates the enclosure and that wiring routes meet NEC/UL requirements for a 200 A, 240 V system.
