Feature → Business Impact → Application: Amperage rating of 600 A supports high-load feeders and motor circuits, reducing nuisance fuse changes and improving uptime in demanding applications. This enables faster commissioning and predictable protection, particularly in manufacturing lines and processing plants where reliability is non-negotiable. Feature → Application of 240 V operation and two-pole configuration simplifies integration into standard low-voltage distribution schemes, enabling plug-and-play compatibility with existing enclosures and switchgear. Feature → Class H fuse provision provides a robust interrupting medium optimized for high-energy circuits, lowering arc-flash risk and improving protection coordination with downstream protections in complex motor control centers. Feature → Fusible without neutral configuration reduces wiring complexity in three-phase systems, which simplifies field wiring and minimizes potential for incorrect neutral connections. Feature → Enclosure rated NEMA 12 and NEMA 3R with painted galvanized steel delivers superior dust, moisture, and corrosion resistance for harsh environments, extending service intervals and lowering maintenance costs. Feature → UL Listed, NEC 230.62 barrier compliance, and NEMA 4X capability (where stainless construction is chosen) reassure inspectors and operators, supporting regulatory adherence and reducing downtime during audits. Feature → Conductor compatibility with #2 to 600 kcmil copper/aluminum enables versatile, high-capacity hookups without mid-span splices, improving reliability and reducing installation time. Feature → Large dimensions (63 in height, 23.66 in width, 12.75 in depth) and weight (157 lb) reflect a robust, field-serviceable enclosure that installers can access with standard tools, minimizing time on site. Feature → 75 to 200 hp protection for 3-phase systems (std fuse/time delay) supports a wide range of motor loads, enabling solution scalability across multiple lines without replacing switchgear. Feature → 1-year warranty (or 18 months from shipment) provides assurance against manufacturing defects, reducing lifecycle risk and supporting procurement confidence.

FAQs
For install, verify the enclosure fits the existing footprint (63 in x 23.66 in x 12.75 in) and supports the 157 lb weight. Ensure conductors range from #2 to 600 kcmil Cu/Al and two wires are used in a two-pole configuration. Maintain proper clearance for maintenance and incorporate NEC barrier practices per NEC 230.62. Use appropriate mounting hardware and confirm UL Listed status for system acceptance.
DH225NWKX is rated for 600 A at 240 V with a two-pole, fusible configuration without neutral. It uses Class H fuses and supports 75 to 200 hp in three-phase applications with standard fuse/time delay coordination. The switch is UL Listed and designed to protect motor feeders while meeting NEMA 12/3R enclosure requirements.
Yes. The unit offers NEMA 12 and NEMA 3R enclosure protection with painted galvanized steel, delivering dust and moisture resistance suitable for harsh environments. For additional corrosion resistance in stainless environments, consider NEMA 4X-rated configurations where applicable. This makes it suitable for manufacturing floors, outdoor enclosures, and demanding process facilities.
The DH225NWKX is UL Listed and NEC 230.62 barrier compliant, ensuring safety and regulatory alignment. The enclosure ratings of NEMA 12/3R provide environmental protection, while the 4X rating option offers enhanced stainless steel protection for tougher environments. These certifications support compliance during audits and safety inspections in industrial facilities.
Its robust painted galvanized steel enclosure and UL/NEC compliance reduce installation rework and inspection findings, lowering lifecycle risk. The unit’s compatibility with large conductors and a high current rating minimizes spare parts needs and fuse replacements, contributing to lower maintenance cost and improved uptime across high-demand lines.
