FAQs
For proper installation, ensure panel cutouts and mounting clearances meet the enclosure requirements for a NEMA 12/3R unit. Route four wires with a dedicated neutral conductor, connect up to 600 kcmil feeders, and verify a Class H fuse is provisioned. Maintain proper torque on lugs and ensure clear access for safe operation and maintenance.
The DH326NDKV is rated for 600 A at 240 V and supports motor loads up to 200 hp in three-phase configurations. It is a three-pole, four-wire device with neutral, designed to provide reliable isolation and protection for high-power motors in industrial applications, reducing inrush impact and enabling safe motor startup.
Yes. The unit features a NEMA 12/3R enclosure with painted galvanized steel, suitable for indoor and select outdoor environments. Its rugged construction resists dust, moisture, and incidental exposure, helping minimize maintenance cycles and extend service life in plant yards, loading docks, or exposed control areas.
The DH326NDKV is UL Listed and employs a NEC 230.62 compliant barrier, meeting widely adopted electrical safety standards. These certifications help ensure regulatory compliance for installed equipment, simplify inspections, and support safe maintenance procedures in industrial facilities.
Expect reduced downtime due to robust isolation and rapid fault clearance, fewer fuse replacements thanks to Class H provisions, and simplified wiring with a 4-wire neutral design. Over time, this translates to lower maintenance labor costs, improved equipment availability, and a faster return on investment in high-demand production lines.
