Eaton Specification Sheet - DH266FWKW
Selling Policy 25-000 - Distribution and Control Products and Services
High current capability and voltage resilience meet demanding loads. The DH266FWKW offers a 600 A amperage rating and 600 V maximum, enabling safe isolation of large motors and feeders. This reduces the need for oversized equipment and streamlines panel design, delivering faster installation and tighter protective coordination with upstream breakers within industrial power distribution architectures. Corrosion-resistant enclosure provides robustness. The NEMA 4X enclosure made from 306 stainless steel withstands washdowns and outdoor exposure, delivering long service life in harsh environments such as food processing, chemical plants, and water treatment. This durability lowers maintenance costs and reduces the frequency of unscheduled outages. Cartridge fuse provision and quick-change capability improve maintenance. Fusible without neutral and two-pole configuration simplify wiring and fuse replacement, cutting downtime and spare parts inventory. The unit’s size and conductor capacity support straightforward retrofits into existing control schemes. Visible blade and window improve safety and uptime. The enhanced visible blade enables quick status checks without opening the enclosure, reducing risk during maintenance and speeding fault diagnosis in high-availability lines. Compliance, compatibility, and support are integral. UL Listed certification ensures regulatory compliance; the 64 in depth, 26 in width, and 13 in height accommodate large cable entries up to590kcmil Cu/Al per pole, while offering Eaton service and warranty continuity for reliable plant operation.
