Feature → Business Impact → Application: 200 A amperage with two‑pole cartridge‑fuse configuration ensures reliable overcurrent protection for demanding loads, reducing the risk of equipment damage and downtime in manufacturing lines. This translates to lower maintenance costs and improved uptime in industrial facilities where quick fault isolation matters. Feature → Application: NEMA 12/3R enclosure with painted galvanized steel provides robust protection against dust, moisture, and incidental contact, enabling safe operation in crowded control cabinets and damp environments while reducing enclosure corrosion-related costs. Feature → Application: Fusible without neutral configuration simplifies wiring and reduces neutral bus complexity for two‑wire circuits, accelerating installation and minimizing wiring errors on mid‑line feeders. Feature → Application: Wiring capability of #6 AWG to 300 kcmil Cu/Al supports diverse feeder topologies, enabling scalable installations from small motor circuits to large distribution runs with one part family. Feature → Application: UL Listed certification and documented HP rating—up to 50 HP (1PH @ 480/600 V)—provide clear performance expectations for motor control and drive applications, supporting compliance and procurement confidence. Feature → Application: Cartridge fuse provision and window/visible blade notes enable fast inspection, safer operation, and easier replacement part sourcing, which translates into reduced maintenance time and improved safety posture in industrial plants.

FAQs
The DH264FDKW is a two-pole, 200 A unit designed for two-wire circuits with a cartridge fuse. Install in a NEMA 12/3R enclosure, ensuring the incoming and load conductors are #6 AWG to 300 kcmil Cu/Al. Use proper torque on lugs, verify 600 V max rating is suitable for the system, and confirm the device is clearly accessible for maintenance and inspection.
This safety switch uses cartridge fuses and is configured fusible without neutral. Wiring supports #6 AWG through 300 kcmil Cu/Al, enabling a range of feeders from small motor loads to larger distribution circuits. Ensure the fuse class is compatible with the system requirements and source replacement cartridges through the Eaton channel to maintain performance integrity.
Yes. It is rated for heavy commercial and industrial applications and features a NEMA 12/3R enclosure with painted galvanized steel, providing dust and moisture protection. UL Listed certification adds regulatory confidence, while the two‑pole, 200 A design supports demanding loads up to 50 HP per 1 phase at 480/600 V.
The DH264FDKW carries UL Listed certification, which supports compliance in many markets. Verify project compliance by cross‑checking the UL Listed status on Eaton’s product sheet and cross‑referencing local electrical codes (CE/IP considerations as applicable in your region). For installation, follow Eaton’s guidelines in the specification sheet to ensure proper application and safe operation.
Eaton provides a warranty of one year from the date of installation or eighteen months from shipment, whichever comes first. Regular maintenance recommendations include periodic visual inspection of the window and blade alignment, verifying fuse integrity, and ensuring enclosure seals remain intact. Maintain spare cartridges on hand to minimize downtime during fuse replacements and schedule periodic electrical checks aligned with system maintenance cycles.
