Feature → Business Impact → Application: The DH265FWKV uses a corrosion‑resistant 304 stainless steel enclosure rated to NEMA 4X, which delivers reliable housing in washdown and outdoor environments, reducing corrosion‑related failures and service calls. This directly lowers maintenance costs and extends service life for food processing, water treatment, and chemical handling plants. Application: Install on outdoor switchgear or process lines where exposure to moisture, chemicals, or washdowns is routine. Feature → Business Impact → Application: The unit is rated for 400 A at 600 V and supports two poles with two wires, enabling high‑current isolation with minimal voltage drop during disconnection. This improves startup safety and enables quick discharge of energy in rapid‑shutdown scenarios, reducing risk during machine changes and maintenance. Application: Heavy machinery, conveyors, and large motors in manufacturing floors. Feature → Business Impact → Application: Class H fuse provision and fusible without neutral configuration offer targeted protection for motor circuits while simplifying protection scheme integration. You gain lower fused‑link costs and straightforward compliance with a robust safety strategy. Application: Motor control centers and critical load feeders where precise overcurrent protection is required. Feature → Business Impact → Application: Enhanced visible blade improves fault status visibility, accelerating troubleshooting and reducing downtime during maintenance windows. Application: Field services and panel retrofits where quick visual confirmation speeds repair time. Feature → Business Impact → Application: 64 in length, 26 in width, and 13 in height with a 115 lb weight provide a compact yet rugged footprint suitable for retrofit into existing enclosures without major structural changes. Application: Plant expansions and equipment upgrades where space constraints exist. Feature → Business Impact → Application: HP rating of 50 at 250 Vdc confirms compatibility with DC motor drives and higher‑voltage control circuits, enabling broader use in automated lines and robotics where DC power is prevalent. Application: DC motor drives and mixed‑voltage control panels in packaging and material handling.

FAQs
The DH265FWKV is a two‑pole, fusible safety switch designed for 600 V systems and up to 400 A. When retrofitting, verify enclosure dimensions (64 in x 26 in x 13 in) fit your cabinet space, confirm wiring size ranges (2 wires), and ensure mounting provisions align with your frame. Use appropriate conduit entries and verify NEMA 4X sealing for outdoor or washdown areas.
Key ratings include 400 A amperage, 600 V voltage, and a Class H fuse provision with fusible without neutral configuration. This supports high‑current motor circuits and provides selective protection. Confirm conductor sizes such as (2) #1/0 to (2) 300 kcmil copper/aluminum per the installation manual and ensure the wiring method matches NEC requirements for high‑amp, two‑pole protection.
Yes. The enclosure is NEMA 4X rated and constructed from 304 stainless steel, delivering corrosion resistance in outdoor, washdown, and harsh process environments. This makes it well suited for food processing, water treatment, and chemical handling facilities where exposure to moisture or chemicals is routine.
The DH265FWKV carries UL Listed certification and NEC 230.62 compliant barrier capabilities, ensuring safety isolation meets stringent national standards. This supports regulatory compliance in industrial facilities and simplifies QA audits while providing a defensible safety margin for high‑current applications.
The rugged stainless enclosure, high current rating, and reliable fault isolation reduce unplanned downtime and maintenance cycles in demanding environments. By minimizing corrosion‑related failures and enabling faster service with visible blade status, operators achieve improved uptime, lower maintenance costs, and longer service life for critical motor circuits.
