Heavy Duty, Fusible with neutral
Feature → NEMA 4X, 304 stainless steel enclosure delivers outstanding corrosion resistance in outdoor and wash-down environments, even under salt spray and high humidity. Business Impact → This robust enclosure reduces maintenance costs, minimizes unplanned downtime, and extends service intervals across harsh industrial sites. Application → Ideal for outdoor substations, coastal facilities, and wash-down areas where rugged protection and long-term reliability are non-negotiable. Feature → Three-pole, four-wire design with fusible protection and a neutral connection, combined with Class L fuse provision, enables coordinated protection. Business Impact → This configuration reduces fault spread, improves selectivity, and simplifies wiring by providing a clear neutral path for control circuits. Application → Especially valuable in motor control centers and process panels that require reliable neutral switching and measured protection performance. Feature → 1200 A amperage rating supports large loads without excessive panel crowding or the need for multiple devices. Business Impact → This enables easier protection coordination, reduces install time, and lowers total installed cost for MCCs and main feeders. Application → Large industrial motors, pumps, and process lines where high current handling simplifies downstream protection strategies. Feature → 600 V voltage rating with Class L neutral protection, designed for elevated reliability. Business Impact → Ensures correct voltage coordination, improved selectivity, and safer shutdowns, aligning with corporate safety programs. Application → Strong fit for plant-wide power distribution, control panels in manufacturing, outdoor equipment, and service entrances fed by 600 V networks in demanding facilities. Feature → UL Listed certification and corrosion-resistant hardware provide documented reliability and traceable performance for long-term operation in challenging environments. Business Impact → Aids compliance with safety standards, simplifies supplier qualification, reduces audits, and lowers project risk through predictable, repeatable performance across fleets. Application → Suitable for manufacturing lines, utilities, and process plants requiring rugged, code-compliant safety switching with minimal maintenance and rapid troubleshooting when disturbance occurs.

FAQs
When installing the DH368NWK, ensure adequate space for its large enclosure (19.99 in depth, 41.46 in width, 73.77 in height) and clear access for three-pole, four-wire wiring. Use proper knockouts and a robust support surface, with neutral bus routing to the Class L fuse provision. Verify 600 V system compatibility and that UL Listed components are used throughout the assembly.
The DH368NWK is UL Listed and features a NEMA 4X corrosion-resistant enclosure crafted from 304 stainless steel. UL Listing confirms compliance with electrical safety standards, while NEMA 4X protection ensures suitability for outdoor and wash-down environments. Together they simplify procurement, safety audits, and long-term reliability in challenging industrial facilities.
Fusible with neutral means the switch provides fused protection on all three poles while maintaining a neutral path, enabling coordinated protection and safe power return. Class L fuses offer selective protection and arc-flash mitigation. In practice, this reduces fault energy transferred to downstream equipment and simplifies safe servicing of motor and process circuits.
Yes. The DH368NWK ships with Class L fuse provision and a neutral connection designed to work with standard neutral buses in a three-pole, four-wire configuration. It supports 1200 A loads at 600 V and is compatible with UL Listed components, ensuring system-wide compliance and consistent protection coordination across the installation.
The robust 304 stainless steel, NEMA 4X enclosure and UL Listed construction reduce corrosion-related maintenance and downtime, extending service intervals and lowering replacement costs. With a single heavy-duty device handling high current and neutral coordination, fleets reduce inventory and commissioning time, delivering lower total cost of ownership over the life of the installation.
