FAQs
The DH368NRKV is a three-pole, four-wire fusible safety switch rated for 600 V and 1200 A. It accepts four conductors labeled as #1/0 to 750 kcmil Al per the electrical design, with a NEMA 3R enclosure for outdoor or damp indoor use. Plan for accessible blade visibility and proper neutral connections to ensure safe operation.
This model is UL Listed and supports NEC 230.62 compliant barriers, ensuring safe separation of live parts. The NEMA 3R enclosure provides weather resistance, suitable for outdoor installation, while Class L fuse provisions align with standard protection schemes. These certifications help with compliance documentation and regulatory audits.
It is ideal for industrial power distribution and equipment protection requiring large current control, such as motor drives, process lines, and heavy machinery feeders. The 1200 A, 600 V rating, and four-wire configuration support rugged installations in manufacturing, packaging, and process facilities that demand reliable safety switching.
Plan fuse replacement and neutral servicing within a safe, de-energized workflow. The enhanced visible blades aid in quick verification during maintenance, and the UL Listed status supports documented compliance. Regular inspection of the galvanized enclosure for corrosion and ensuring accessibility to the operator handle minimizes downtime.
Compared with standard disconnects, this unit offers a robust NEMA 3R enclosure, UL Listing, and a high 1200 A rating for heavy-duty currents. Its fusible-with-neutral design, Class L fuse provision, and enhanced blade visibility provide safer operation, faster fault isolation, and long-term cost savings in harsh industrial environments.
