Eaton DD366FWKW-00V3 Double Door Safety Switch - NEMA 4X

Feature → Business Impact → Application: The DD366FWKW-00V3 provides a three-pole, fusible without neutral configuration for compact, reliable isolation in heavy-duty motor circuits, reducing arc flash risk and streamlining wiring during installation. This translates to faster commissioning and a lower total cost of ownership for mission-critical processes in packaging, metal fabrication, and water treatment facilities. The 304 stainless steel enclosure with a NEMA 4X rating delivers superior corrosion and wash-down resistance, enabling compliant operation in corrosive or wet environments without frequent enclosure replacements. As a fused disconnect with a line indicator window, technicians can verify status quickly, minimizing startup delays and improving plant uptime. The 600 A amperage rating and 600 V maximum voltage ensure compatibility with large motors and VFDs, while the HP rating of 400–500 hp (3PH @480/600 V) supports heavy-duty applications in production lines and material handling. UL Listed certification provides compliance assurance for electrical safety programs and risk management. The product’s dimensions (19.31 in depth, 25.32 in height, 77.96 in width) and 265 lb weight highlight its suitability for permanent installations in control rooms and electrical rooms, with improved mounting stability and reduced vibration-related wear. The inclusion of a voltage indicator line and load side window simplifies fault finding and field verification, reducing maintenance time and enhancing reliability in demanding facilities.
