Eaton DD365FWKW-00V2 Fused Safety Switch - UL Listed
Part Number: DD365FWKW-00V2
Quick Summary
Eaton DD365FWKW-00V2 fused safety switch provides reliable line-side isolation for demanding industrial control panels. Many panel builds struggle with corrosion, washdown exposure, and maintenance downtime. This unit is UL Listed and features a NEMA 4X, 304 stainless steel enclosure designed for washdown and harsh environments. It offers three-pole, three-wire operation with Class H fuse provision, supporting 480/600 V systems and up to 400 A. The load-side voltage indicator with window simplifies verification without opening the enclosure, improving safety. For design engineers and procurement teams, this combination translates to reduced downtime, longer service life, and lower total cost of ownership in water-prone or outdoor installations.

Eaton Specification Sheet - DD365FWKW-00V2
High amperage capability and fuse coordination drive meaningful business outcomes. The DD365FWKW-00V2 supports up to 400 A with a Class H fuse provision for reliable motor starting and protection in 3-phase 480/600 V systems, enabling safer line isolation and fewer nuisance trips. This translates to reduced maintenance interruptions and enhanced overall equipment effectiveness (OEE) on high-load production lines, particularly in metal fabrication and packaging applications. The three-pole, three-wire configuration simplifies wiring topology, speeding installation and simplifying future expansion while maintaining compliant protection for large motors. In practice, engineers gain predictable fault response and operators benefit from consistent performance during peak demand.

FAQs
Install as a three-pole, three-wire device with fusible protection (Class H) for 480/600 V service. Ensure panel cutout and mounting align with the unit's 16.41 in depth, 24.32 in height, and 72.46 in width, and connect the line-side and load-side conductors per the Eaton wiring diagram. Use proper torque on terminations and verify UL Listed compliance during commissioning.
The switch is rated for 400 A and 600 V, with three-pole, three-wire configuration and fusible without neutral. It supports up to 250–350 hp for three-phase motors at 480/600 V and uses Class H fuses to achieve appropriate protection and selective coordination.
Yes. It uses a NEMA 4X enclosure constructed from 304 stainless steel, delivering watertight, corrosion-resistant performance suitable for washdown, humidity, and outdoor installations while maintaining safe operation.
Warranty terms follow Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first, providing coverage against manufacturing defects and early failures.
The load-side voltage indicator with window allows visual status verification without opening the enclosure, reducing exposure risk during routine checks and enabling faster, safer maintenance cycles for technicians.
