Eaton DD364FWKW-00V2 fused safety switch - NEMA 4X

Three-pole, fusible without neutral is a foundational feature that delivers full isolation for three‑phase circuits, reducing fault energy and simplifying protective coordination. Business impact includes safer maintenance windows and quicker fault diagnosis, which translates to shorter downtime on conveyors, pumps, and motors in automated lines. This is ideal for applications in manufacturing and processing where reliable disconnection is critical. The switch supports a 200A rating with HP limits of 50, 50/125, and 150 hp at 480–600 V, enabling robust protection for mid‑size drive systems and reducing replacement cost through appropriate overcurrent protection. In practice, you’ll see smoother start-ups and fewer nuisance trips during peak load conditions, improving line throughput and operator confidence. The NEMA 4X, 304 stainless steel enclosure provides corrosion resistance and washdown resilience, extending service life in challenging environments like food processing or chemical plants. This compatibility with harsh environments reduces maintenance cycles and total cost of ownership. The load-side voltage indicator with window offers immediate status visibility, accelerating commissioning and troubleshooting without opening the enclosure. Combined with #6 AWG–300 kcmil wiring capacity, you gain flexible terminations for feeders, motors, and control circuits, simplifying panel design and spare parts stocking. UL Listed certification reinforces compliance with safety standards, supporting code adherence in regulated facilities and customer audits. The heavy‑duty construction and three‑pole design reduce panel space requirements while maintaining accessibility for routine testing and lockout/tagout procedures.
