Eaton Specification Sheet - DD363NDKW-00V2
NEMA 12/3R enclosure with painted galvanized steel provides rugged protection against dust and moisture, reducing corrosion risk and downtime. This physically robust enclosure translates to longer service life in harsh factory environments and easier maintenance access on crowded panels. Fusible with neutral configuration delivers precise overcurrent protection for three-pole, four-wire circuits, improving motor protection and reducing nuisance trips in demanding line conditions, while Class H fuses offer reliable interruption in high-current events. The 600 V rating paired with HP options of 30, 40/60, and 75 hp (1/3PH @480–600 V) supports a broad range of motor loads, enabling a single precursor solution for multiple lines and plants. The voltage indicator load side with a window provides immediate visual confirmation of switch status, minimizing startup errors and enhancing operator safety. Wire sizing accommodates #14-1/0 AWG across four conductors, offering feeder flexibility for diverse installations. The compact footprint and a weight around 50 lb simplify mounting in tight control rooms, while UL Listed certification helps align with compliance programs and procurement requirements. Warranty terms of one year from installation or 18 months from shipment provide lifecycle protection and risk mitigation for procurement and maintenance teams.
