Eaton Specification Sheet - DH363FDKW
Selling Policy 25-000 - Distribution and Control Products and Services
Three-pole design provides complete phase isolation for three-phase motors, with fusible without neutral configuration simplifying wiring and reducing control cabinet clutter. This translates to faster install and clear fault paths, improving diagnostic clarity during maintenance and startup checks in manufacturing, packaging, and material-handling environments. The painted galvanized steel enclosure offers rugged protection, delivering corrosion resistance and reliability in dusty or damp plant areas while maintaining clean enclosure interiors for safer maintenance. The NEMA 12/3R enclosure rating supports indoor and outdoor installations in moderate weather, ensuring consistent performance in production halls, warehouses, and outdoor equipment spaces. Class H fuse provision delivers robust short-circuit protection with selective coordination, helping protect motors and feeders while reducing nuisance tripping during startup surges. A 600 V rating and 100 A capacity support larger load profiles, enabling fewer components in the switchgear lineup and simplifying maintenance. UL Listed certification reinforces safety compliance and accelerates procurement, while the long-term reliability of a heavy duty fusible safety switch minimizes downtime and replacement costs. The Eaton warranty policy adds further protection, aligning with moderate-risk industrial environments and providing assurances during critical uptime windows.

FAQs
DH363FDKW should be installed as a three-pole, three-wire switch with fusible without neutral configuration. Connect three phase conductors to input terminals, ensure the Class H fuse is correctly positioned, and mount within a NEMA 12/3R rated enclosure. Verify 600 V maximum voltage and 100 A rating, and follow local codes during panel assembly and wiring to ensure proper isolation and safe operation.
This unit is rated for 100 A with a 600 V maximum voltage. It supports three-pole operation with three wires and provides HP protection up to 75 hp at 1/3 horsepower on 480/600 V. The enclosure is NEMA 12/3R, and the fuse configuration is fusible without neutral, with Class H fuse provision for robust short-circuit protection.
Yes, the DH363FDKW uses a painted galvanized steel enclosure rated NEMA 12/3R, which supports indoor dusty environments and outdoor installations under appropriate weather protection. For outdoor use, ensure appropriate mounting and protection from direct exposure to harsh conditions, aligning with the NEMA 3R aspects of rugged enclosure design.
The DH363FDKW is UL Listed, confirming compliance with applicable safety standards. While CE or IP ratings are not specified in the datasheet, the UL Listed certification, combined with the NEMA 12/3R enclosure, supports regulatory compliance and reliable performance in industrial settings.
Eaton’s policy for this product is one year from installation or eighteen months from shipment, whichever occurs first. This warranty framework reduces downtime costs by enabling prompt service or replacement if needed, contributing to lower total cost of ownership and more predictable maintenance budgeting for industrial facilities.
