FAQs
The DH327FDKV is a three-pole, fusible without neutral design rated at 800 A and 240 V. Plan for a 57.5 in depth, 27.5 in width, and 12.38 in height enclosure on a solid base or mounted in a compliant panel. Ensure wiring uses appropriate conductors and that the NEC barrier is maintained for safe servicing.
UL Listing confirms conformity to recognized safety standards, while NEC 230.62 barrier compliance ensures safe separation of supply and fault paths. The NEMA 12/3R enclosure further protects against dust and moisture, supporting safe operation in demanding industrial environments.
Yes. The enclosure is rated for NEMA 12 and NEMA 3R environments, with painted galvanized steel providing corrosion resistance. For outdoor use, verify ambient ratings and maintain enclosure integrity; ensure gaskets and hardware are in good condition to preserve protection class.
The unit provides 800 A continuous amperage rating at 240 V and up to 100 hp max for three-phase applications. This makes it suitable for high-demand motors and equipment where reliable isolation and protection are required.
The device supports three-phase wiring with fusible protection and a configuration described as fusible without neutral. It accommodates large conductor sizes up to (4) 750 kcmil Cu/Al and typical feeders like #1/0, enabling flexible field wiring for diverse motor circuits.
