FAQs
The DH222NCK is a two-pole, 60A fusible safety switch with neutral, designed for 240V circuits. It fits standard control panels and motor disconnect installations and features a NEMA 12/3R enclosure, painted galvanized steel for durability. It is ideal for indoor equipment rooms, washdown areas, and moderately harsh environments where dust and moisture protection are required. When planning mounting, ensure adequate space for the 20 in length and 9.5 in width, and consider wiring with three conductors plus neutral per the fusible configuration.
Key ratings include a 60A amperage, 240V voltage, and a two-pole design with fusible neutral. HP handling maxes at 3, 7.5 hp/10, 15 hp/10 hp for 1-phase and 3-phase configurations with standard fuse/time delay at 250Vdc. This supports motor protection for a range of equipment. The unit is UL Listed, providing confidence in safety compliance for industrial installations.
Yes, the DH222NCK uses a NEMA 12, NEMA 3R enclosure and painted galvanized steel construction, offering dust and moisture resistance suitable for indoor and partially outdoor locations. While not rated as a full IP-rated device, the enclosure design and finish provide durability in challenging environments such as warehouses or outdoor equipment bays when protected from direct exposure to the elements.
Plan for periodic fuse inspection and replacement, ensuring the Class H fuse is matched to the motor load and startup requirements. Verify the neutral path integrity and maintain enclosure seals to preserve dust/moisture protection. Regularly check mounting integrity and wiring connections during maintenance outages to minimize downtime and ensure continued safe isolation during servicing.
Eaton provides a warranty per policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. For technical support, consult Eaton's specifications and datasheets, including the DH222NCK datasheet and catalog references, to ensure proper application, replacement fuse availability, and guidance on fault analysis and preventive maintenance.
