Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: The 200 A amperage rating with a 600 V maximum enables the switch to handle large motor loads and high-demand circuits, reducing the risk of nuisance trips and enabling smoother start-ups in pumps, conveyors, and compressors. This translates to measurable uptime gains and safer shutdowns in manufacturing lines and process plants. Feature → Business Impact → Application: NEMA 12/NEMA 3R enclosures provide dust-tight and weather-protected performance, safeguarding electrical components in dusty or outdoor-rated environments and lowering maintenance costs while extending service intervals for industrial automation cabinets and control panels. Feature → Business Impact → Application: Voltage indicator line and load side with a window offers immediate visual status during routine checks, accelerating troubleshooting and preventive maintenance in panel assemblies and switchgear rooms. Feature → Business Impact → Application: Fusible with neutral and Class H fuse configuration ensures selective coordination and safe fault isolation, minimizing damage to downstream equipment and reducing replacement parts and downtime in motor circuits and heavy-duty drives. Feature → Business Impact → Application: Three-pole, four-wire construction simplifies wiring and ground references, enabling faster installation and easier compliance with standard industrial control wiring practices in motor control centers and machine disconnects. Feature → Business Impact → Application: Solid mechanical construction from painted galvanized steel supports long service life in demanding facilities, helping facilities managers meet lifetime cost targets and reduce lifecycle replacements. Feature → Business Impact → Application: UL Listed certification, combined with 49.9 in depth and robust weight, reassures procurement teams of compliance, safety, and compatibility with Eaton and third-party motor control components for electrical protection and control systems.

FAQs
Yes. The DD364NDKW-00V3 is a three-pole, four-wire, fusible safety switch designed for 4-wire 3-phase networks. It supports a 200 A current rating and 600 V voltage rating, with a neutral path provided by the fusible configuration. This makes it suitable for motor feeders and equipment disconnects in industrial installations.
Key ratings include 200 A amperage, 600 V voltage, NEMA 12 enclosure rating, and Class H fuse provision. It is fusible with neutral and supports hp ratings up to 50/125/150 hp for 1/3 phase at 480 to 600 V. These specs enable safe disconnects and protective coordination for medium-size motor circuits.
The unit uses a NEMA 12, NEMA 3R enclosure with painted galvanized steel, making it appropriate for dust-tight indoor installations and weather-protected outdoor or semi-enclosed spaces. It’s ideal for manufacturing floors, pump rooms, and electrical rooms where rugged protection and cleanable surfaces help extend service life.
Warranty follows Eaton policy 25-000: one year from installation or 18 months from shipment, whichever occurs first. For maintenance, rely on the voltage indicator to verify status, inspect fuse integrity, and ensure enclosure seals remain intact to maintain NEMA protection class during routine safety checks.
Plan for a stable mounting surface to support the unit’s 85 lb weight and 49.9 in depth. Use three-pole four-wire wiring with a neutral, and exploit the windowed voltage indicator for quick fault diagnosis. The UL Listed certification also helps streamline procurement and compliance audits, reducing project risk and downtime in new builds or retrofits.
