Eaton DH328NWK316 Heavy Duty Fusible Safety Switch - UL Listed

Three-pole construction with a 1200 A rating at 240 V delivers substantial fault and overload protection for demanding motor control and process lines. This capability translates to improved operating reliability and reduced fuse replacement cycles, particularly in high-current starts typical of heavy machinery. In practice, it fits three-wire and four-wire installations in control panels and switchgear where robust isolation is non-negotiable. 316 stainless steel enclosure with a NEMA 4X rating provides superior corrosion resistance in washdown, coastal, and outdoor installations. That durability directly lowers maintenance intervals and extends service life in harsh environments, reducing total cost of ownership. It also supports compliance with plant hygiene and outdoor exposure requirements while maintaining a clean, professional installation appearance. Class L fuse provision with fusible with neutral configuration enables precise protection coordination for four-wire circuits. This arrangement minimizes arc energy and helps avoid unnecessary shutdowns, lowering lifecycle costs and improving safety margins. The combination supports standardization across cross-functional teams and reduces spare parts variety. UL Listed certification and NEC-compliant barrier reinforce regulatory readiness and supplier qualification. By meeting recognized standards, the unit minimizes QA review time and streamlines procurement for regulated industries. These certifications also support traceability and warranty claims, boosting procurement confidence. Designed for three-pole, four-wire systems in heavy-duty environments, it supports straightforward mounting and panel integration. The enclosure dimensions (19.94 in length, 70.31 in height, 41.47 in width) and a 510 lb weight inform shipping, rigging, and space planning. Operators benefit from predictable installation workflows and reliable service life in demanding facilities.
