Eaton Specification Sheet - DD361NDKW
Three-pole fusible with neutral provides coordinated protection for three-phase systems, enabling safe isolation during maintenance. This reduces arc-flash exposure and minimizes nuisance tripping, cutting downtime and repair costs. It fits typical motor and control circuits on conveyors, presses, and processing lines. NEMA 12 / NEMA 3R enclosure provides environmental protection against dust and moisture, translating to longer mean time between failures and reduced corrosion risk. It is well-suited for factory floors, washdown areas, and sheltered outdoor locations. Fuse class provision Class H ensures dependable overload protection for a range of motor loads up to 20 hp at 1/3PH on 480/600 V systems, helping you meet safety standards while minimizing nuisance trips. The windowed design enables quick fuse-status checks without opening the enclosure, boosting maintenance efficiency and reducing exposure. The unit’s footprint and weight (37.49 in L, 12.33 in W, 8.22 in H, 37 lb) support straightforward panel mounting and wire routing in crowded electrical rooms, while the painted galvanized steel enclosure resists corrosion in demanding environments. Combined with UL Listed safety compliance and a 1-year to 18-month warranty window, this switch delivers predictable lifecycle costs and reliable protection for industrial automation applications.
