FAQs
Plan for a three‑pole, 240V configuration with a neutral connection and a NEMA 12 enclosure. Ensure suitable clearance for the 19.99 in depth, 41.46 in width, and 73.77 in height, and verify mounting provisions support the 510 lb weight. Use proper protective labeling and follow UL Listed installation guidelines to optimize safety and easy future maintenance.
The DH328NDK is designed as a standard 3‑pole, 1200A fusible safety switch with a neutral, suitable for integration in Eaton power distribution ecosystems as well as compatible third‑party switchgear within typical panel and subpanel layouts. Confirm matching busbar footprint, terminal block style, and enclosure access to ensure seamless fit and serviceability.
Key specs include 1200A amperage rating, 240V voltage, three‑pole arrangement, and UL Listed certification. The NEUT feature simplifies wiring, while the NEMA 12 enclosure provides environmental protection. These factors collectively influence fault isolation speed, system downtime, and regulatory compliance in manufacturing or process industries.
Ideal for heavy machinery, large manufacturing lines, and centralized panel boards that require high‑current, fault‑isolating protection. Its neutral option and rugged NEMA 12 enclosure make it suitable for interior industrial spaces with dust and moisture exposure, helping to maintain continuous operation and safer maintenance routines.
Fusible safety switches like the DH328NDK offer robust protection with fewer moving parts, reducing failure modes. Regular fuse replacement after fault events is predictable and manageable, contributing to lower unexpected downtime. The UL Listed rating supports ongoing compliance audits, potentially lowering warranty and risk costs over the unit’s life.
