Eaton Specification Sheet - DD367FDKW-00V3
Feature → Business Impact → Application: The DD367FDKW-00V3 delivers an 800A amperage rating with a three-pole, three-wire configuration, supporting large 3PH motors up to 500 hp at 480/600 V. This enables OEMs and integrators to consolidate controls and protect high-current loads with a single, reliable device, reducing cascade wiring and component count in motor control centers. Application-wise, it’s ideal for heavy industry and production lines where uptime and safety are critical. Feature → Business Impact → Application: The NEMA 12, NEMA 3R enclosure provides dust-tight and weather-resistant protection, shielding internal components from harsh shop floor conditions and extending service intervals. This translates to lower maintenance costs and fewer unplanned outages in manufacturing plants and outdoor installations. Feature → Business Impact → Application: Voltage indicator line and load side with a viewing window allow quick, non-contact status checks, empowering maintenance crews to verify circuit state before servicing and reducing fault-diagnosis time during shifts. Feature → Business Impact → Application: Fusible without neutral with Class L protection delivers reliable short-circuit protection while allowing the use of common, standard fuse types. This simplifies spares management and reduces downtime during fuse replacements in 600 V distribution networks. Feature → Business Impact → Application: Three-pole, heavy-duty double-door construction offers robust mechanical integrity and straightforward wiring for three-phase electrical systems, ensuring safer operation and easier retrofits in existing panels or new projects. Feature → Business Impact → Application: The product’s compatibility with conductor sizes up to (4)750 kcmil and branch wiring options supports scalable installations, enabling future capacity expansion without replacing the switch. The integrated warranty and Eaton support ecosystem further enhance total cost of ownership by reducing service risk and ensuring quick access to replacement parts.
