FAQs
When installing the DD368FWKW-00V2, plan for a three-pole, three-wire configuration with conductors up to 750 kcmil and #1/0 per leg. Allow space for the 575 lb unit, and ensure mounting on a stable support compatible with a 27.18 in depth, 43.11 in height, and 91.02 in width footprint. The NEMA 4X, 304 stainless enclosure provides corrosion resistance in washdown areas, while the load-side voltage indicator with window enables quick status checks during commissioning and maintenance.
Class L fuses offer fast-acting protection with coordination suited to large motor loads, helping to limit damage to upstream equipment during faults. Fusible without neutral configuration simplifies wiring schemes and reduces neutral conductors in the circuit. This combination supports selective protection, improves motor life, and enhances safety in 600 V, 3-phase systems typical of industrial facilities.
Yes. The unit uses a NEMA 4X enclosure crafted from 304 stainless steel, designed for washdown and outdoor exposure. This corrosion-resistant construction, paired with UL Listed protection, ensures reliable operation in harsh environments such as chemical plants, food and beverage processing, and outdoor substations, while maintaining safe isolation and easy maintenance access.
Key certifications and standards include UL Listed safety compliance for the fused switch assembly and a NEMA 4X enclosure rating that supports watertight and dust-tight performance. These features help ensure regulatory alignment and safety compliance in industrial power distribution, especially for environments requiring rugged protection and visual status indicators.
Maintenance benefits include a robust stainless-steel enclosure that resists corrosion, reducing repainting and part replacement costs, and a load-side window indicator that speeds preventive checks. The unit’s high current rating and durable construction translate to extended service life for critical motor feeders, lower downtime, and a favorable total cost of ownership in high-demand plants.
