Exterior durability drives long-term uptime in harsh environments, and the DH268NWK delivers with a corrosion-resistant stainless-steel enclosure that meets NEMA 4X. This design supports outdoor installation, washdown zones, and coastal or factory floors where moisture and chemicals challenge equipment. The result is lower replacement cycles and reduced maintenance costs across the life of the switch. Fuse configuration and protection are built around a Class L fuse provision and a fusible-with-neutral setup in a two-pole, three-wire arrangement. The 1200 A amperage rating and 600 V voltage rating give designers a reliable main-disconnect option for large feeders, improving fault management and system reliability. In practice, this means more predictable fault clearance and better coordination with downstream protective devices. UL Listed certification and NEC barrier compliance provide regulatory confidence and safer labor conditions during installation and operation. The NEMA 4X stainless enclosure further supports dust, water, and corrosion resistance, reducing the risk of panel contamination in demanding environments. Together, these features help facilities meet industry standards while maintaining productivity. Installation and compatibility considerations are simplified by the standard two-pole design and clear Eaton specifications. The unit’s rugged construction is designed for field mounting under typical industrial layouts, and its 19.99 in depth, 41.46 in width, and 73.77 in height guide enclosure coordination in control rooms and switchgear assemblies. This makes sourcing, stocking, and commissioning more efficient. Warranty terms support TCO for asset managers: one year from installation or eighteen months from shipment. By choosing a proven, UL-listed, stainless-steel solution with long service life and minimal maintenance, facilities can reduce spare parts inventory and downtime costs while ensuring safety and compliance across critical power distribution.

FAQs
It is designed for 600 V industrial power distribution with a two-pole, fusible-with-neutral configuration. The DH268NWK supports up to 1200 A and is suitable for main disconnects and feeders in manufacturing, water treatment, and process facilities. When integrating, verify fuse type against Class L, follow Eaton installation guides, and coordinate with downstream protective devices for reliable fault clearance.
The NEMA 4X stainless-steel enclosure provides outdoor and washdown resilience, protecting against moisture, dust, and corrosion. Plan for secure mounting, maintain adequate clearance for doors and wiring, and follow NEC barrier guidelines to keep spaces compliant. Ensure proper grounding, seal integrity, and gasket maintenance during service intervals to preserve protection over time.
UL Listed certification confirms electrical safety and reliability, while NEC barrier compliance supports control-panel protection. Although SIL or CE labels are not listed in the data, the combination of UL Listed status, NEMA 4X enclosure, and corrosion resistance helps address regulatory and safety requirements. Documented certifications simplify audits and commissioning.
The warranty runs one year from installation or eighteen months from shipment, whichever comes first. Maintenance is typically limited to periodic fuse checks, enclosure seals, and verification of labeling and grounding. The rugged stainless enclosure and Eaton design reduce the frequency of maintenance, supporting lower total cost of ownership in high-demand facilities.
Electrical ratings include 1200 A amperage, 600 V, and a fusible-with-neutral arrangement in a two-pole, three-wire configuration. The fuse class provision uses Class L fuses, with a UL-listed safety switch in a NEMA 4X enclosure for reliable isolation and protection of large feeders and critical loads.
