FAQs
The DH268FWK is designed for harsh settings with a NEMA 4X stainless enclosure and corrosion resistance from 304 stainless steel. For outdoor or washdown areas, ensure proper clearance and mounting height, use appropriate interior wiring lugs, and follow torque specs per the Eaton datasheet. Plan for room for two large feeders and safe handling due to its 455 lb weight. Regular inspection of sealing integrity and fuse accessibility aids long-term reliability.
This switch accommodates large feeders with conductor ranges up to (4)1/0 through (4)750 kcmil Cu/Al, two wires total. It supports fusible without neutral and uses Class L fuses for selectivity. When wiring, verify lug torque, insulation distances, and maintain proper clearance for heat dissipation. Consult the specification sheet for installation diagrams and torque values to ensure code-compliant, safe operation.
