800 A amperage rating and 240 V operation translate to a single device capable of handling large motor loads and feeder circuits without oversizing. This results in fewer components, lower total installed cost, and improved coordination with upstream protective devices. Ideal for service entrances or main motor feeders in manufacturing lines, packaging, and processing facilities. Heavy-duty NEMA 1 enclosure with painted steel provides indoor protection against dust and incidental contact, improving enclosure integrity and reducing risk of equipment contamination. This design supports easier installation in standard control panels and minimizes field modifications, saving time during commissioning. Class L fuse provision and fusible with neutral configuration deliver safe, code-compliant shutdowns and predictable fault clearing for three-wire systems in harsh industrial environments. The two-pole, three-wire arrangement simplifies wiring schemes and enhances protection coordination with upstream devices, reducing wiring errors. UL Listed and NEC barrier compliance reinforce regulatory adherence, while the compact footprint and modular lug design streamline panel layout and future upgrades. Conductor capacity supports up to four #1/0 through four 750 kcmil aluminum conductors, enabling scalable motor and feeder connections without upgrading enclosure hardware. Overall, the DH227NGK combines reliability, ease of maintenance, and manufacturing-ready compatibility for busy facilities.

FAQs
When installing the DH227NGK, ensure a standard indoor NEMA 1 enclosure is used and that the panel layout accommodates its 57.5 in length, 27.5 in width, and 12.38 in height. Verify conductor range (up to four #1/0 through four 750 kcmil aluminum) and align wiring with the two-pole, three-wire configuration. Adhere to NEC 230.62 barrier requirements and secure UL Listed protection during commissioning to optimize startup times and minimize wiring errors.
DH227NGK provides an 800 A amperage rating and 240 V voltage rating, supporting three-phase motor feeders. It accepts a conductor range of up to four #1/0 through four 750 kcmil aluminum conductors. The device uses a fusible with neutral configuration and a two-pole, three-wire design, enabling straightforward connection to standard industrial power systems while maintaining proper protection coordination.
Yes. The DH227NGK is designed for large three-phase power applications, including motor feeders. It offers high current capacity (800 A) and HP ratings up to 250 hp at 240 V with time-delay protection, making it suitable for starting and stopping heavy loads in manufacturing environments. The unit’s Class L fuse and fusible-with-neutral configuration support reliable fault clearing and safe isolation during maintenance.
The DH227NGK is UL Listed and complies with NEC 230.62 barrier requirements for indoor installations. It features a NEMA 1 rated enclosure for indoor protection and a painted steel enclosure. Catalog notes indicate three-phase horsepower ratings are grounded for B phase, and the product is designed to meet typical industrial safety and performance standards.
The DH227NGK reduces downtime through reliable isolation and durable construction, lowering unscheduled maintenance. UL Listed and NEC barrier compliance help avoid regulatory delays, while the robust enclosure and fuse configuration protect critical feeders from faults. With a large current rating and straightforward wiring, maintenance tasks become quicker, cables are easier to reposition, and long-term operational costs are reduced through fewer component changes.
