Feature → Business Impact → Application: The DD365NDKW-00V2 supports 400 A and 600 V with a three-pole, four-wire configuration, enabling it to safely switch large motor loads and reducing panel count in medium-sized protective schemes used in manufacturing lines and equipment rooms. This directly improves energy management and overall equipment efficiency (OEE) by minimizing switching losses and simplifying wiring layouts in new builds or retrofits. Application-wise, it is ideal for motor control centers and line-start applications where reliable protection is critical and space is at a premium. Feature → Business Impact → Application: Fusible with neutral (Class H) provides selective short-circuit protection and streamlined fault isolation, reducing outage duration and improving maintenance planning in continuous operations. This supports compliance with safety standards while enabling quicker, safer replacement of fuses during routine servicing or during capacity upgrades. Feature → Business Impact → Application: NEMA 12 and NEMA 3R enclosure rating delivers dust-tight and rain/dust-resistant protection, extending service life in workshops, outdoor equipment pads, or dusty production floors. The outcome is lower replacement costs and fewer unscheduled shutdowns when subjected to harsh environmental conditions. Feature → Business Impact → Application: Load-side voltage indicator with window gives immediate visual feedback during testing and maintenance, shortening diagnostic time and allowing technicians to verify circuit status without opening the enclosure. This translates to faster turnarounds on scheduled maintenance and safer lockout/tagout procedures across plant floors. Feature → Business Impact → Application: UL Listed certification and Eaton’s warranty terms provide regulatory confidence and predictable support, helping with vendor qualification and long-term total cost of ownership (TCO) calculations. Combined with a footprint designed for standard switchgear, it simplifies procurement and installation planning, aligning with enterprise sourcing goals. Feature → Business Impact → Application: Dimensions of 16.41 in depth, 24.32 in height, and 72.46 in width enable straightforward integration into existing protected spaces or replacement of legacy devices, reducing field engineering time and enabling smoother retrofits in aging installations. This is particularly beneficial for OEMs and integrators targeting high-uptime packaging lines or process automation systems.

FAQs

For tight spaces, verify enclosure clearance to allow door swing and user access, note the device footprint of 16.41 in depth, and plan for 72.46 in width integration with adjacent gear. Ensure proper cable routing for four wires and the neutral connection, and follow lockout/tagout procedures during installation.
Key specs include a 400 A amperage rating, 600 V voltage rating, three-pole, four-wire configuration, Class H fuse provision, and a load-side voltage indicator with window. It supports up to 250-350 hp for three-phase motors at 480/600 V, with UL Listed certification for electrical safety compliance.
Yes, it is suitable for 480/600 V three-phase systems. The maximum horsepower rating is 250 HP at 480 V and 350 HP at 600 V for three-phase loads, making it appropriate for medium-to-large motor control requirements in manufacturing or processing facilities.
The product is UL Listed and enclosed in a NEMA 12, NEMA 3R rated housing, providing dust-tight and weather-appropriate protection. This combination supports compliance in diverse environments and simplifies approval workflows for industrial projects.
The load-side voltage indicator with window accelerates diagnostics, reducing maintenance time and unplanned downtime. The rugged enclosure and long service life of fused protection reduce replacement costs, while the included warranty (one year from installation or 18 months from shipment) provides predictable support and clearer total cost of ownership calculations.
