Eaton Specification Sheet - DD367NWKW-00V2
The 800 A amperage rating with a three-pole, four-wire fusible-with-neutral configuration ensures fast, selective protection for large motors and feeders, reducing nuisance trips and protecting downstream equipment in motor control centers and large conveyors. The 304 stainless steel enclosure with a NEMA 4X rating delivers corrosion resistance and watertight protection in washdown, chemical, and outdoor environments, lowering maintenance costs and extending service life. A load-side voltage indicator with a window provides immediate status visibility, cutting fault-detection time and enabling proactive maintenance in process lines and packaging facilities. The fuse class provision with Class L fusing supports safe interruption of motor loads while keeping voltage drop to a minimum, supporting reliability for up to 500 hp motors. Large feeder connections accommodate (4) 750 kcmil conductors or smaller, simplifying field wiring in expansive plant layouts. With a weight of roughly 300 lb and dimensions of 86.73 in x 22.16 in x 26.57 in, the unit is designed for robust, long-term service and straightforward integration into existing stacks or switchgear. The included warranty and UL Listing reinforce compliance, while compatibility with standard Eaton components eases installation and future expansion in industrial automation environments.
