Eaton DH225NWK Heavy Duty Fusible Switch - NEMA 4X
Part Number: DH225NWK
Quick Summary
Eaton DH225NWK heavy duty fusible safety switch delivers reliable isolation for 3‑phase machinery in demanding industrial environments. Facilities often wrestle with corrosion, moisture, and downtime when enclosures fail to deliver robust seals or compatible fuse configurations. UL Listed certification and a NEMA 4X corrosion-resistant enclosure provide durable protection, while 316 stainless steel construction supports long service life in washdown or outdoor applications. This model combines a neutral-capable, two-pole design with straightforward installation and scalable capacity, offering essential safety for power distribution with minimal maintenance. By aligning with Eaton's reliability standards, it helps shorten project timelines, reduce spare-part inventories, and improve overall equipment availability for manufacturing, processing, and mining operations.
