Eaton Specification Sheet - DD364FDKW-00V3
Fusible without neutral is a compact wiring solution that reduces components while delivering dependable overcurrent protection for three-wire, three-pole motor circuits. This translates into simpler assemblies, fewer part numbers, and faster commissioning in manufacturing lines. The NEMA 12/3R enclosure provides dust-tight and moisture-resilient protection ideal for indoor control panels and semi-enclosed outdoor areas, enabling longer service life with less preventive maintenance. The built-in voltage indicator line and load-side window allow quick visual verification of circuit status, shortening downtime during lockout/tagout and routine inspections. With 200 A nominal capacity and HP ratings up to 150 hp at 480/600 V, the switch supports heavy motor loads while maintaining safe disconnection. The wiring range of #6 AWG through 300 kcmil supports large feeders without excessive splicing, reducing labor and potential fault points. UL Listed certification and Eaton’s warranty policy further bolster reliability, ensuring predictable performance and lower total cost of ownership over the equipment lifecycle.

FAQs
For safe, codes-compliant installation, verify the panel cutout and mounting space can fit a three-pole, heavy-duty double-door switch. The unit requires about 17.18 in wide by 11.62 in high and 49.9 in deep, with a NEMA 12/3R enclosure. Use conductors from #6 AWG to 300 kcmil, observe the fusible without neutral configuration, and follow lockout/tagout procedures during servicing.
This switch is rated for 600 V and up to 200 A, with maximum HP ratings of 50/125/150 hp (1/3PH @480, 600 V). It is three-pole, three-wire, fusible without neutral, and uses Class H fuses. It accommodates large conductors and provides a secure disconnect for motor control centers, ensuring safe and reliable operation in high-voltage applications.
Yes, the DD364FDKW-00V3 is UL Listed, supporting compliance with common electrical protection standards. The warranty follows Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. This provides assurance for uptime and a predictable service window, aiding maintenance planning and total cost of ownership considerations.
Absolutely. The device supports wiring from #6 AWG up to 300 kcmil, enabling direct connections to large motors and feeders without intermediate splices. The heavy-duty lugs and three-wire design simplify power distribution in control panels while maintaining robust short-circuit protection. Always verify terminal torque and installation guidelines per the manufacturer data sheet.
The built-in voltage indicator on both the line and load sides provides immediate status visibility, reducing maintenance time and enhancing safety during servicing. This feature, combined with the rugged steel enclosure, supports quick fault isolation and reliable operation in demanding environments, helping crews confirm de-energization before work begins.
