Eaton DH322FRK Heavy Duty Fusible Safety Switch - UL Listed
Part Number: DH322FRK
Quick Summary
Eaton DH322FRK is a heavy duty fusible safety switch for service entrance protection and equipment isolation. Operators often struggle with finding robust, code-compliant switches that can handle 60 A at 240 V in harsh locations. This unit ships with UL Listed certification and a NEMA 3R enclosure, using Class H fuses for reliable fault isolation. In practice, the DH322FRK delivers predictable HP ratings and supports service-entrance configurations with an optional Neutral Kit, simplifying installation across industrial panels. This translates to reduced downtime, easier maintenance, and improved compliance across power distribution layouts.

FAQs
Yes. The DH322FRK is specified as fusible without neutral by default, but Eaton provides a Neutral Kit option to enable service-entrance installations. When added, it simplifies wiring, allows neutral grounding as required by the application, and maintains UL Listed status. Ensure the Neutral Kit is compatible with the 60 A, three-pole configuration and follow the catalog notes for correct field modifications.
The DH322FRK is rated for 60 A at 240 V and supports motor load HP up to 3 HP, with higher HP ratings of 7.5/10 and 15/10 HP depending on the designated service and configuration (1/3 PH at Std/TD/250 Vdc). This makes it suitable for moderate power circuits in industrial equipment and process lines, while preserving safe disconnect capability during faults.
Yes. The DH322FRK employs a NEMA 3R enclosure with painted galvanized steel, designed for outdoor and damp environments. This construction provides weather resistance, reduces maintenance needs, and helps maintain performance in exposed utility rooms, exterior panels, and protected outdoor locations where reliable isolation is critical.
The DH322FRK is UL Listed and features a NEMA 3R enclosure, classifying it for outdoor and damp locations. These certifications support code compliance for industrial electrical installations and facilitate safe operation across service entrances, motor circuits, and protected panels.
Warranty coverage follows Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. For ROI, expect reduced downtime due to reliable isolation, easier maintenance with a robust galvanic enclosure, and durable, field-wiring friendly 14-2 Cu/Al connections that support long service life in demanding environments.
