Eaton Specification Sheet - DD367FWKW-00V2
NEMA 4X, 304 stainless steel enclosure provides corrosion resistance and washdown durability, reducing maintenance cycles and extending service life in harsh environments. This translates to lower total cost of ownership and less downtime in food and beverage, chemical, or outdoor installations. Fusible without neutral with Class L protection delivers selective fault isolation and simplified spares logistics, improving reliability for heavy machinery and large motor circuits. The load-side voltage indicator with a window enables quick, non-intrusive status checks during commissioning and routine inspections, speeding startup and reducing lockout times. A three-pole, three-wire configuration rated at 800 A and 600 V supports up to 500 hp motors, reducing panel complexity and enabling scalable, modular protection for conveyors and presses. Conductor terminations accommodate #1/0 through (4) 750 kcmil, easing installation and future upgrades while maintaining robust safety margins. UL Listed certification further reinforces regulatory compliance, providing confidence to procurement and QA teams during audits and supplier qualification.

FAQs
DD367FWKW-00V2 is well suited for washdown environments thanks to its NEMA 4X, 304 stainless steel enclosure. For installation, mount on a level surface with appropriate sealant and gasket, ensure door clearance, and connect the three-pole, three-wire terminals. Note this model is fusible without neutral, so plan conductor terminations accordingly and follow lockout/tagout procedures during service.
Yes, it is rated for 600 V three-phase systems and supports up to 800 A. It is designed as a three-pole, three-wire device with conductor termination suitable for #1/0 to (4) 750 kcmil conductors. This broad range simplifies motor connections for large horsepower drives up to 500 hp (3PH @480/600 V), reducing the need for separate terminal blocks.
DD367FWKW-00V2 uses fusible protection without a neutral and features Class L fuse provision for protected circuits. The device is UL Listed and supports up to 800 A and 600 V, with a 500 hp rating. The fusible design provides selective coordination and rapid fault isolation for motor circuits, helping minimize downtime and maintain system safety.
The load-side voltage indicator with a window enables quick status checks during commissioning and routine maintenance without opening the enclosure. This reduces lockout times, improves safety during testing, and speeds troubleshooting by confirming voltage conditions on downstream equipment, while the UL Listed, NEMA 4X enclosure supports safe operation in harsh environments.
Selecting the DD367FWKW-00V2 delivers reliability, safety, and lifecycle cost advantages. The rugged 304 stainless enclosure and NEMA 4X rating withstand washdown and corrosive environments, while the 800 A rating and 500 hp capability reduce panel count and motor protection costs. UL listing and Class L protection support regulatory compliance, faster procurement, and lower maintenance expenditures.
