FAQs
The DH368FDKV is a three‑pole, three‑wire heavy duty fusible safety switch designed for 600 V systems. It accepts large conductor sizes (up to 750 kcmil aluminum) and is compatible with NEMA 12/3R enclosures. For retrofit projects, verify panel space, ensure proper neutral handling per Class L fuse provisions, and follow UL safety guidelines during disconnect installation. Proper wiring practices and torque specs from Eaton’s data sheet should be followed to ensure reliable operation and code compliance.
The device is rated for 1200 A and 600 V, with a three‑pole configuration and fusible without neutral. This allows protection for high‑current feeders and large motors. When selecting fuses, ensure Class L attributes are matched to the load characteristics, and confirm that conductor sizing and overcurrent protection align with NEC 230.62 requirements for safe, coordinated protection in your installation.
Yes. The DH368FDKV features a painted galvanized steel enclosure rated for NEMA 12 and NEMA 3R conditions, making it suitable for dusty or damp environments commonly found in manufacturing, packaging, and processing facilities. Its HDSS designation and UL listing provide confidence for installations requiring rigorous safety and reliability standards, including panelboards and motor control centers.
This switch is UL Listed and includes NEC 230.62 (C) compliant barriers, ensuring worker safety during live maintenance and compliant panel labeling. The NEMA 12/3R enclosure further supports protection against environmental factors. These certifications help streamline inspections and audits, while enabling engineers to demonstrate code compliance during project handovers.
Routine maintenance focuses on inspecting enclosure integrity, fuse status, and electrical connections per manufacturer recommendations. The 1200 A, 600 V rating supports fewer components for large capacity installations, potentially reducing spare parts and maintenance time. Over time, the UL listing and robust enclosure design contribute to lower lifecycle costs by minimizing unscheduled downtime and extending service intervals.
