Eaton DH361NWK316 features a corrosion-resistant 316 stainless steel enclosure with a robust NEMA 4X protection rating. This construction delivers superior resistance to humidity, splashes, and corrosive atmospheres, reducing downtime and maintenance costs in waterfront, food processing, chemical, or washdown environments. Field teams value predictable performance, shorter maintenance windows, and longer service intervals, especially where equipment sits over lengthy production runs or in outdoor facilities. The unit is a three-pole, four-wire safety switch with fusible with neutral configuration. This arrangement provides reliable isolation for three-phase circuits while preserving neutral paths, supporting safe motor control and drive applications. The 10-inch depth and compact footprint fit standard enclosure spaces, and the 22 lb weight offers a practical balance between rugged protection and on-site handling. Fuse class provision is Class H, delivering protective coordination and quick, clean disconnection during fault conditions. Rated at 30A and 600V, it supports motor and equipment loads up to 20 hp depending on voltage and configuration. The fusible-with-neutral design also simplifies wiring schemes in control panels and minimizes nuisance tripping in demanding industrial processes. Wiring and dimensions support straightforward installation. Accepts #14-2 AWG Cu/Al conductors, with product dimensions of 10 in depth, 17.88 in height, and 8.13 in width. The 22 lb unit is easy to handle during installation, and UL listing coupled with a NEC-compliant barrier provides regulatory confidence for new builds or panel retrofits in harsh environments. Compatibility and serviceability remain key strengths. The DH361NWK316 integrates with Eaton catalogs and spare-part inventories, offers durable, long-life operation, and is backed by a one-year warranty from the Eaton policy. With its 600 V rating, NEMA 4X enclosure, UL Listing, and corrosion-resistant enclosure materials, it helps facilities meet safety, reliability, and uptime targets across demanding industrial processes.
