Selling Policy 25-000 - Distribution and Control Products and Services
UL Listed certification paired with a NEMA 12/3R enclosure delivers durable protection against dust and moisture in harsh environments. This pairing translates to fewer field faults and a simpler regulatory path for industrial facilities, enabling faster startup after maintenance. Voltage indicator on the load side with a window provides quick status visibility, reducing mis-wiring and enabling faster diagnostic cycles in live environments. The 800 A amperage rating supports large motors and high inrush loads, minimizing nuisance trips and improving line continuity for critical processes. Fusible with neutral Class L protection offers selective coordination and safer shutdown during faults, lowering energy waste and simplifying arc-flash mitigation planning. Three-pole, four-wire configuration with a 600 V rating covers standard motor control setups up to 500 hp, while the 86.73 in length, 22.16 in height, and 26.57 in width ensure compatibility with common panel layouts. The 300 lb enclosure adds ruggedness for stair-step installations and field rewiring. Overall, the unit enhances reliability, safety, and regulatory compliance for industrial power distribution.

FAQs
This unit measures 86.73 in in depth, 22.16 in in height, and 26.57 in in width, with an approximate weight of 300 lb. Its heavy-duty, three-pole, four-wire design in a NEMA 12/3R enclosure supports mounting in standard control panels and switchgear. Ensure adequate front accessibility for voltage indicator viewing and consider dedicated space for routing four wires and cables to maintain a safe, code-compliant installation.
Key specifications include an 800 A amperage rating, 600 V voltage rating, and up to 500 hp for 3-phase applications at 480/600 V. It uses a fusible with neutral Class L fuse configuration across three poles with four wires, and includes a voltage indicator load side with a viewing window for quick status checks in routine maintenance and fault diagnosis.
Yes. The switch is designed for 480/600 V three-phase systems and supports motors up to 500 hp, making it suitable for large motors and motor control centers in industrial environments. Its robust three-pole, four-wire configuration and high amperage capacity help manage high inrush and startup currents typical of heavy-duty equipment.
The DD367NDKW-00V2 carries UL Listed certification, which supports safety compliance for industrial electrical equipment. It also features a NEMA 12/3R enclosure, indicating suitability for dust-tight and weather-protected installations. Together, these specifications help meet typical industrial safety and reliability standards required in power distribution and control applications.
The voltage indicator on the load side with a window enables quick visual confirmation during maintenance, reducing inspection time. UL Listing and robust NEMA enclosure improve reliability in harsh environments, lowering downtime and replacement costs. The high 800 A rating and 500 hp capacity reduce the need for frequent upgrades in growing facilities, delivering longer service life per installation and improved total cost of ownership.
