FAQs
The DH324FWK316 is a three-pole, three-wire unit rated for 200 A at 240 V with a NEMA 4X, 316 stainless enclosure. It supports #6-300 kcmil Cu/Al conductors and has a length of 37.5 in, height 11.5 in, and width 19 in. Mounting should consider panel space, wiring clearances, and thermal management to maintain 200 A continuous protection.
The 200 A amperage rating with Class H fuses provides precise protection for high-inertia motors and demanding loads. The fusible-without-neutral configuration supports three-phase operation at 240 V, delivering reliable interrupting capability and limiting fault energy to downstream devices, which reduces motor stress and improves overall reliability during starts and stops.
Yes. The DH324FWK316 uses a NEMA 4X enclosure constructed from 316 stainless steel, offering excellent corrosion resistance and weather sealing. This makes it appropriate for outdoor installations, wash-down areas, and chemically aggressive environments where protection against moisture and contaminants is essential.
The switch is UL Listed and includes a NEC 230.62 compliant barrier, ensuring safe separation between live parts and control circuits. These certifications support regulatory compliance during audits and streamline approvals for safety and reliability in industrial installations.
Eaton provides a warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. Regular maintenance should focus on fuse replacement, enclosure integrity, and terminal torque checks to sustain protective performance, reduce unplanned downtime, and maximize return on investment in critical power-distribution equipment.
