Enclosure and material: The 304 stainless steel NEMA 4X enclosure delivers exceptional corrosion resistance and washdown durability, reducing maintenance downtime in harsh environments and extending service intervals for outdoor or wet-area installations. This translates to lower total cost of ownership and fewer field service interruptions in food & beverage, chemical processing, and outdoor equipment applications. Fuse configuration with neutral: Fusible with neutral simplifies control-circuit protection, improves arc-flash safety, and streamlines wiring schemes, enabling faster commissioning and easier compliance with safety standards on complex motor loads. Amperage rating and HP capability: With a 400 A rating and up to 350 hp (3PH @480/600 V), it supports demanding motor loads, reducing the need for upstream protection devices and enabling compact, cost-effective panel designs in plant automation. Voltage rating and wiring: A 600 V, three-pole, four-wire configuration ensures straightforward integration with typical three-phase power systems, improving wiring clarity and reliability during harmonics or fault conditions. Load-side voltage indicator: The built-in voltage indicator on the load side with window speeds fault verification without opening the enclosure, helping maintenance teams diagnose issues quickly and minimize downtime. Certifications and warranty: UL Listed certification and a robust warranty framework provide regulatory confidence and predictable support, strengthening compliance programs and protecting capital investments in critical infrastructure.

FAQs

The DD365NWKW-00V2 is designed for harsh environments and washdown areas due to its 304 stainless steel, NEMA 4X enclosure. For installation, ensure adequate space for wiring and cable entry, verify compatibility with a three-phase 600 V supply, and plan for a neutral path in fusible configurations. The unit’s 16.41 in depth, 24.32 in height, and 72.46 in width should be accommodated in the panel footprint, with correct mounting hardware and gasket sealing to maintain enclosure integrity.
The DD365NWKW-00V2 features a three-pole, four-wire design with a 400 A amperage rating and HP ratings up to 250 or 350 hp (3PH @480/600 V). This enables direct protection of large motors without oversized upstream devices, enabling compact panels and reducing wiring complexity. Ensure motor protection and feeder circuits align with Class H fuse provisions for reliable motor-start and controlled shutoff.
Yes, the unit includes a voltage indicator on the load side with a window, allowing quick visual verification of circuit status without opening the enclosure. This feature supports faster maintenance checks, reduces exposure risk, and helps technicians confirm voltage presence during troubleshooting or lockout-tagout procedures.
The DD365NWKW-00V2 carries UL Listed certification and uses a NEMA 4X enclosure with a 304 stainless steel body, ensuring protection against dust, water ingress, and corrosion. These attributes support compliance with industrial safety codes and environmental protection requirements, particularly in washdown, outdoor, or chemical-processing applications.
Investing in the DD365NWKW-00V2 can reduce downtime due to rapid fault identification (load-side indicator), extend enclosure life with stainless steel corrosion resistance, and lower spare-part needs by consolidating upstream protection. The robust UL certification and warranty further reduce maintenance risk, while the 400 A, 600 V rating accommodates powerful motors, enabling longer service intervals and faster panel commissioning in automation environments.
