FAQs
The DD324FDKW-00V3 is designed for three-phase systems up to 200 A and 240 V, featuring a three-pole configuration. It is suitable for machine panels, switchgear, and motor feeders in industrial environments. With a NEMA 12/3R enclosure and wiring capacity up to #6 AWG-300 kcmil, it integrates smoothly with standard control circuits and protective devices in new builds or retrofits.
Key specifications include a 200 A amperage rating, 240 V voltage rating, fusible without neutral, and Class H fuse provision. It supports up to 50, 50/125, or 150 hp (1/3 PH at 480/600 V) and accommodates wiring from #6 AWG to 300 kcmil. Three-pole, three-wire configuration with line and load voltage indicators enhances safety and visibility.
Yes, the device provides an HP rating that includes 50/125 and up to 150 hp for 1/3-phase configurations at 480/600 V. While its continuous operation is specified at 240 V, the higher-voltage HP ratings indicate suitability for protection and switching of motors fed from higher voltage sources, aligning with typical industrial motor control center applications when used with appropriate upstream components.
The switch is UL Listed, ensuring safety and compliance for industrial use. It comes in a dust-tight NEMA 12 enclosure suitable for indoor use and a NEMA 3R enclosure option for outdoor or damp environments. The clear voltage indicators on both the line and load sides further support safe maintenance and troubleshooting.
The integrated voltage indicators with a window allow quick, at-a-glance verification of line and load statuses, reducing diagnostic time and minimizing unnecessary lockout cycles. This convenient visibility lowers labor costs, shortens downtime during servicing, and improves overall maintenance efficiency for panels and equipment relying on rapid fault isolation.
