FAQs
Yes. The DH265FWKW is a two-pole, two-wire safety switch rated for up to 600 V and 400 A, with a cartridge fuse configuration that fits standard heavy-duty panels. Its 64 in L x 26 in W x 13 in H footprint should be matched to your enclosure openings, and the unit’s NEMA 4X stainless enclosure supports integration in challenging environments. Always verify field wiring practices per local codes prior to installation.
Key specs to confirm include amperage rating (400 A), voltage rating (600 V), HP rating (50 at 250 VDC), fuse configuration (cartridge, fusible without neutral), and the enclosure rating (NEMA 4X). For motor control and drives, ensure your switch aligns with the drive current and DC bus requirements, and plan for proper shutoff sequencing in your control architecture.
Yes. The DH265FWKW features a 304 stainless steel enclosure with a NEMA 4X rating, designed to resist corrosion and withstand washdown, damp, and outdoor conditions. This makes it well-suited for food processing, chemical plants, and outdoor installations where cleanliness and protection are critical, helping to extend service life and reduce maintenance downtime.
Regular fuse replacement according to the cartridge fuse specification and maintaining the visible blade window for quick status checks are central practices. UL Listed certification supports regulatory compliance, while the rugged enclosure minimizes corrosion-related repairs. Plan preventive maintenance around indicated HP and voltage ratings to avoid overstressing components and to sustain peak performance.
Common applications include heavy commercial and industrial environments such as motor drive systems, robotic conveyors, power distribution panels, and process equipment requiring reliable isolation. The unit’s 400 A rating, 600 V capability, and NEMA 4X enclosure make it appropriate for harsh production floors, chemical plants, and outdoor installations where durability and safety compliance are essential.
