Eaton DH368NWK316 Fusible Safety Switch - NEMA 4X

316 stainless steel enclosure provides corrosion resistance and a durable NEMA 4X protection level for harsh environments, including outdoor installations and chemical processing lines. This design minimizes maintenance and downtime by resisting aggressive atmospheres, reducing enclosure-related failures, and extending service life in demanding facilities. The rugged enclosure supports reliability in industries such as water treatment, food and beverage, and petrochemical processing. Three-pole, four-wire configuration with fusible with neutral and Class L fuse provision enables precise protection coordination and safe isolation of high-current circuits in main feeders and motor circuits. This arrangement reduces nuisance tripping, simplifies upstream protection schemes, and lowers maintenance costs by enabling selective protection and faster fault clearance. Applications include large motor feeders, process equipment, and outdoor substations where reliable disconnects are critical. A 1200 A amperage rating at 600 V provides high-current switching in a single, compact assembly, enabling more efficient panel layouts and fewer components. The heavy-duty construction reduces the need for multiple devices, minimizes wiring complexity, and shortens installation time, delivering tangible capital expenditure savings. It is well-suited to distribution panels and motor control centers that demand robust, code-compliant protection with predictable fault behavior. UL Listed and NEC 230.62 barrier compliant status offer clear regulatory alignment and safer installations in demanding environments with strict wiring codes. The NEMA 4X enclosure, stainless steel material, and Class L fuse provision together ensure consistent performance while simplifying compliance documentation, audits, and inspections. This combination supports asset protection programs and reduces risk in high-stakes facilities such as water, energy, and chemical processing plants. Warranty support and lifecycle services under Eaton policy 25-000 provide assurance during the first year, or 18 months from shipment, whichever occurs first. This reduces procurement risk, lowers total cost of ownership, and improves maintenance planning by enabling predictable budgeting and timely replacements. Aligned with OEM specifications and turnkey project budgets, the DH368NWK316 fits seamlessly into capital projects and long-term reliability strategies.
