FAQs
The DH363FDKWJ-USOE is a three-pole, three-wire fusible switch rated for 100 A at 600 V, housed in a NEMA 12 / NEMA 3R painted galvanized steel enclosure. It fits standard switchgear footprints and supports retrofit into panels and enclosures that accommodate Class J fuses and #14-#1/0 Cu/Al conductor sizes, simplifying integration into existing protection schemes.
Class J fuses provide a proven protection class for industrial switches, offering predictable interrupting performance and coordinated protection with the switch. This reduces nuisance trips, limits arc exposure, and simplifies fuse stocking and replacement, contributing to safer startup sequences and lower maintenance costs over the life of the equipment.
Yes. The enclosure is rated for NEMA 3R and NEMA 12, supporting indoor and protected outdoor applications. The painted galvanized steel construction adds corrosion resistance, making it appropriate for environments with exposure to humidity or wash-downs, provided the installation complies with protection and drainage guidelines.
The unit supports up to 100 A at 600 V, is fusible without neutral, and accepts conductors ranging from #14 to #1/0 Cu/Al across three wires. This makes it suitable for motor control and general protection in three-phase systems, enabling reliable isolation and switching for demanding loads.
Eaton provides a one-year limited warranty from the date of installation or eighteen months from shipment, whichever occurs first, per the standard policy. This coverage supports parts and workmanship, reinforcing confidence in performance and access to authorized service and replacement parts.
