FAQs
Yes. The DH463FDKW is a four-pole, four-wire device that uses cartridge fuses for fault isolation. It supports Cu/Al conductors from #14 to #1/0 and provides reliable, safe isolation across all phases, making it suitable for industrial motor control centers and process lines.
The unit uses a NEMA 12 / NEMA 3R enclosure, offering protection against dust, moisture, and temperature variations. This makes it appropriate for harsh factory floors, washdown areas, and other challenging environments where durable electrical protection is required.
The switch measures 29 inches in depth, 17 inches in width, and 9 inches in height, with an approximate weight of 39 pounds. These dimensions influence panel cutouts, mounting clearances, and crane or hoist planning for installation in constrained spaces or retrofit projects.
The DH463FDKW carries UL Listed certification and is built into a NEMA 12/3R enclosure. These certifications support compliance with common industrial safety and electrical protection standards, enabling safer operation and easier procurement validation for regulated facilities.
A one-year warranty from installation or eighteen months from shipment (whichever occurs first) helps limit maintenance costs. The cartridge fuse design simplifies replacement, while the rugged enclosure and high-visibility blades reduce downtime and service time, contributing to a favorable ROI in industrial environments.
