FAQs
For DH265FDKW installations in NEMA 12/3R environments, ensure adequate clearance around the enclosure for wiring and maintenance access. The unit is a two-pole, two-wire switch with a cartridge fuse provision, so plan panel space for the 64.5 inch depth and accommodate proper conductor routing. Verify door clearance for the visible blade window and confirm UL compliance and panel compatibility before wiring.
DH265FDKW is designed with a cartridge fuse configuration and a two-pole, two-wire layout that align with many existing feeder circuits. Its NEMA 12/3R enclosure offers rugged protection compatible with standard industrial panels, while the 400 A rating supports sizeable loads. Retrofit projects benefit from straightforward wiring, quick fuse changes, and the windowed blade for safe status checks during commissioning.
Key performance specs include a 400 A amperage rating and a maximum 600 V rating, with a 50 hp at 250 Vdc capability for DC motor applications. The two-pole, two-wire configuration supports essential motor protection and disconnecting needs, while the cartridge fuse provision ensures reliable overcurrent protection. These specs help size the switch to motor feeders and DC drive circuits in industrial settings.
The DH265FDKW is UL Listed and designed for NEMA 12 and NEMA 3R enclosures, aligning with common industrial safety and protection standards. The enhanced visible blade feature supports quick, safe operation during maintenance, and the rugged galvanized enclosure is built for enduring service in harsh environments. These certifications simplify regulatory compliance for industrial installations.
Total cost of ownership includes initial purchase, installation time, and ongoing maintenance. The DH265FDKW uses cartridge fuses, which simplify replacements and reduce downtime. A one-year warranty from installation (or 18 months from shipment) provides a baseline protection period, and UL/NEMA compliance minimizes the risk of costly nonconformity. Plan for periodic inspection of the blade window and enclosure integrity to maintain reliability.
