High amperage capability and clear fault isolation drive reliability in demanding installations. The DH224NDK delivers 200 A at 240 V in a two-pole, three-wire configuration with fusible protection including neutral, enabling clean shutdowns and precise fuse coordination. This translates to reduced arc flash exposure and safer motor starts in manufacturing lines and processing equipment. Rugged enclosure supports indoor and outdoor service. The NEMA 12/3R rating protects against dust, moisture, and incidental washdown, while a factory option to modify for rainproof operation (via drain hole modification) simplifies outdoor installations and minimizes downtime. Compatibility with standard fuses and time-delay profiles yields flexible motor control. HP ratings up to 15, 25 hp on 1-phase and 60 hp/40 hp on 3-phase (with standard fuse/time delay at 250 Vdc) cover a broad range of services, reducing the need for multiple switchgear SKUs and simplifying spare parts. UL Listed certification and NEC 230.62 barrier compliance support regulatory and safety audits. The safety switch's fusible-with-neutral design simplifies wiring and improves fault clearing times, resulting in faster maintenance and lower energy waste when circuits are de-energized. Eaton's warranty policy (1-year from installation or 18 months from shipment) and accessible technical support reduce risk, while simple mounting and standard conduit entries speed up installation by electrical teams.

FAQs
The DH224NDK supports a two-pole, three-wire configuration with a 200 A rating at 240 V. It accommodates #6-300 kcmil Cu/Al conductors and uses a fusible-with-neutral setup. Enclosure ratings are NEMA 12 and NEMA 3R, making it suitable for indoor panel installations or weather-protected outdoor locations when field-modified for rain resistance.
Rated for 200 A, the device supports HP ratings of 15 and 25 hp for 1-phase service, and 15, 60, or 40 hp for 3-phase service depending on fuse type and time-delay. These ratings assume a standard fuse profile and a 250 Vdc context, enabling flexible motor control for a broad range of equipment.
Yes, through its NEMA 3R capability for rain-prone environments. The catalog notes a field-modifiable option to achieve rainproof operation by opening a factory drain hole, though this requires proper installation practices and sealing after modification to maintain enclosure integrity.
The DH224NDK carries UL Listed certification and NEC 230.62 barrier compliance for safe, code-conformant installations. Warranty terms are 1 year from installation or 18 months from shipment, whichever occurs first, with standard Eaton support channels for troubleshooting and replacement parts.
Field-protective design with neutral fusible wiring simplifies maintenance and fuse replacement, reducing downtime during faults. Its robust enclosure and field-mod options minimize service interruptions in outdoor or washdown environments, while UL/NEMA compliance supports quicker regulatory approvals, contributing to lower total cost of ownership and faster return-to-service after faults.
