The enclosure uses 304 stainless steel and a NEMA 4X rating to resist corrosion and washdowns, reducing maintenance cycles and extending service life in demanding environments such as food processing and chemical plants. This feature translates to lower lifecycle costs and greater system availability, especially where outdoor or splash-prone installations are common. The device provides a 200 A amperage rating at 240 V in a two-pole, three-wire configuration with a neutral, enabling safe isolation of powered machinery and quick fault clearance, which minimizes unplanned downtime and protects critical equipment. With a Class H fuse provision and fusible with neutral configuration, the switch delivers reliable short-circuit protection and orderly power-down sequences for PLCs, conveyors, and process lines. The robust UL Listed status and NEC barrier compliance further reassure installers and end users about code compliance and risk mitigation, supporting faster approvals and project timelines. Its dimensions (37.5 in length, 11.5 in height, 19 in width) and 55 lb weight offer a compact yet sturdy footprint that fits standard control gear enclosures, simplifying retrofit and new-install projects. The unit’s 240 V three-wire, neutral design aligns with common industrial power distributions and reduces wiring complexity during panel assembly, while the compatibility with standard control devices and cables (#6-300 kcmil Cu/Al) decreases installation time and material costs. In field practice, operators report improved reliability, easier spare-part sourcing, and clearer protection coordination thanks to the unit’s explicit fuse characteristics, visible blade, and corrosion-resistant construction.

FAQs
Installers should plan for a 37.5 inch depth, 19 inch width, and 11.5 inch height footprint to fit standard switchgear enclosures. The device supports three-wire, neutral configurations at 240 V with a 200 A rating and Class H fuses. Ensure proper clearance for the NEMA 4X stainless steel enclosure and verify UL Listed and NEC barrier compliance during commissioning to meet code requirements.
Key specs include a 200 A amperage rating, 240 V voltage rating, two-pole configuration with neutral, fusible with neutral, and availability with standard fuses and time-delay options. It supports up to 15–60 hp depending on the phase and fuse arrangement, and uses Cu/Al conductor sizes #6-300 kcmil. The unit is UL Listed and designed for safe isolation in industrial panels.
Yes. The enclosure is NEMA 4X rated and constructed from 304 stainless steel, delivering excellent corrosion resistance in washdown areas and harsh industrial environments. This makes it well-suited for food processing, chemical, and outdoor installations where moisture and cleaning agents are present.
The DH224NWK316 is UL Listed and designed to comply with NEC barrier requirements. Its NEMA 4X stainless enclosure further supports compliance in environments requiring splash protection and robust protection of internal electrical components, reducing regulatory risk and streamlining approvals.
The combination of corrosion resistance, durable stainless enclosure, and reliable 200 A/240 V protection reduces maintenance frequency and unplanned downtime. A longer service life and UL/NEC compliance simplify audits and repairs, while 304 stainless steel construction minimizes replacement costs in harsh environments, yielding a favorable total cost of ownership over time.
