FAQs
DH223NWKW is a two-pole, three-wire device with neutral designed for 240 V circuits up to 100 A. It supports standard wiring options (Cu/Al #14–#1/0) and fits typical control panel layouts. For retrofit projects, verify enclosure clearance, ensure compatibility with existing fuses or time-delay configurations, and confirm a proper neutral connection to maintain correct motor protection.
The switch provides 100 A amperage, 240 V rating, and a flexible HP range of up to 7.5, 15, or 30 hp depending on configuration (1- or 3-phase with standard fuse/time delay at 250 Vdc). It is most effective for heavy-duty motors in industrial conveyors, pumps, and processing equipment where reliable isolation and protection are required.
Yes. DH223NWKW uses an EnviroLine stainless enclosure with a NEMA 4X rating, designed for corrosion resistance and outdoor exposure. This makes it well-suited for chemical plants, water treatment, food processing, and outdoor installations where washdowns or harsh conditions are common and enclosure integrity is critical.
DH223NWKW carries UL Listed certification and is enclosed in a NEMA 4X stainless housing, which supports compliance with electrical safety and environmental protection standards. This combination helps satisfy industrial procurement requirements and simplifies regulatory audits for facilities with strict safety and corrosion resistance criteria.
The device reduces downtime through reliable isolation and visible blade/window verification, cutting maintenance time and unplanned outages. Its corrosion-resistant EnviroLine stainless enclosure lowers corrosion-related replacements, while a 1-year to 18-month Eaton warranty provides risk mitigation during initial operation and early-life maintenance cycles.
