Eaton Specification Sheet - DD368NWKW-00V3
Feature → Business Impact → Application: 1200 A amperage rating supports large motors and reduces panel congestion, improving electrical reliability and allowing closer packing in MCCs used in heavy industry. This translates to fewer protection devices in series, faster troubleshooting, and improved uptime for continuous process lines. Feature → Business Impact → Application: NEMA 4X watertight enclosure protects the switch in harsh environments, lowering corrosion risk in outdoor substations and washdown zones, enabling safe outdoor installation without extra enclosure costs. Feature → Business Impact → Application: Fusible with neutral simplifies wiring and ensures neutral continuity for three-pole four-wire systems, reducing start-up time and potential mis-wiring during maintenance. Feature → Business Impact → Application: Three-pole, four-wire configuration supports standard industrial power distribution, compatible with most motor control centers and switchgear, delivering plug‑and‑play integration for new builds and retrofits. Feature → Business Impact → Application: 500 hp maximum rating at 480/600 V enables protection of large-HP motors, ensuring reliable motor protection for high‑load drives and process equipment. Feature → Business Impact → Application: 600 V rating aligns with common plant electrical hierarchies, simplifying procurement and improving compliance for medium-voltage applications across manufacturing facilities.
