Eaton DH264FWKX Heavy Duty Fusible Safety Switch - NEMA 4X
Part Number: DH264FWKX
Quick Summary
Eaton DH264FWKX heavy duty fusible safety switch is designed to protect electrical feeders and motor circuits in harsh industrial environments. In corrosive or damp installations, ordinary switches struggle with moisture and corrosion, leading to maintenance overhead and downtime. UL Listed, NEMA 4X EnviroLine stainless enclosure, and NEC 230.62 barrier compliance provide reliability and regulatory alignment in demanding plants. Two-pole, two-wire operation supports up to 200 A rating at 600 V, while a neutral/ground lug kit enables service entrance configurations. With Eaton Selling Policy 25-000, one year from installation or eighteen months from shipment, whichever occurs first, owners gain predictable downtime and long-term ownership value, reducing lifecycle costs and improving plant safety. The unit’s rugged construction also enhances safety and operability for a wide range of control architectures.

Product Category
Heavy Duty, Harsh Environment - EnviroLine
EnviroLine stainless enclosure delivers corrosion resistance in washdown and coastal environments, reducing maintenance frequency and extending service life. This directly lowers downtime and replacement costs while ensuring reliable performance in demanding applications such as food processing, water treatment, and heavy manufacturing. The Class H fuse provision with fusible configuration provides robust overcurrent protection for two-pole, two-wire circuits up to 200 A at 600 V, minimizing nuisance trips and maintenance complexity in critical systems like conveyors and pumps. Wire sizes range from #6 AWG to 300 kcmil Cu/Al, enabling seamless integration with large feeders and motor circuits, reducing field rewiring time and accelerating commissioning. Service entrance readiness with neutral/ground lug kit compatibility and NEC barrier compliance supports safer, code-conforming installations, while UL Listed certification reinforces regulatory alignment. The compact dimensions and 43 lb weight simplify mounting in crowded control panels and canopies, and the 50 hp max rating for single-phase operation at high voltage expands the range of compatible loads. Warranty coverage through Eaton policy adds predictable support, lowering total cost of ownership and safeguarding uptime across plant life cycles.
