FAQs
DH226FDKW is a two-pole, two-wire fusible safety switch designed for indoor industrial installations. Plan for the 58 in x 27.5 in footprint and 142 lb weight, ensure a NEMA 1 painted steel enclosure, and confirm compatibility with #2-600 kcmil aluminum or #1/0-750 kcmil aluminum conductors. Verify alignment with motor loads up to 200 hp (3PH @ time-delay fuse) and ensure adequate space for window visibility during lockout/tagout.
The DH226FDKW provides a 600A amperage rating and supports up to 75 hp standard or 200 hp for 3-phase loads using the time-delay fuse. This rating informs motor protection strategies and helps prevent nuisance trips on high-inertia equipment while enabling proper coordination with upstream protective devices.
Yes. It uses a painted steel enclosure with a NEMA 1 rating and a window/visible blade for quick status checks. UL Listed certification further confirms safety compliance for heavy commercial and industrial applications, while the rugged construction and protective features reduce maintenance frequency in challenging environments.
The unit is UL Listed and rated for NEMA 12/3R configurations. These certifications support compliance in regulated industrial settings and provide assurance for safe operation, easy vendor approvals, and consistent performance across demanding applications.
Visibility through the window and blade, plus a robust enclosure, simplify inspections and lockout/tagout procedures, reducing downtime. The 1-year warranty (or 18 months from shipment) adds lifecycle value, while the unit’s high-conductor compatibility and motor protection ratings minimize spares and rework during upgrades or expansions.
