Eaton DH165URKN DC disconnect - NEMA 3R, UL Listed
Part Number: DH165URKN
Quick Summary
Eaton DH165URKN DC disconnect provides reliable single-throw isolation for 600 VDC power systems in industrial and solar applications. Maintenance teams often face downtime and errors when compatibility or rating are unclear, leading to costly field revisions. UL Listed certification and a NEMA 3R enclosure with painted galvanized steel provide confidence in safety and long-term durability, even in outdoor or harsh environments. With factory-installed neutral assemblies and a compact single-pole design, installation is faster, wiring is simpler, and ongoing service costs are reduced. This makes it a practical choice for panel builders and maintenance teams seeking reliability, compliance, and faster project turnover.

FAQs
When installing the DH165URKN, ensure alignment with a single-pole, 600 VDC circuit and confirm a 400 A rating suits the load. Verify the NEMA 3R enclosure is appropriate for outdoor or damp locations and plan for the 12.398 in depth, 24.12 in width, and 44.31 in height. Use factory-installed neutral assemblies to simplify wiring and reduce field errors.
The DH165URKN is a non-fusible, single-throw DC disconnect rated for 400 A at 600 VDC across one circuit. It provides reliable isolation without internal fuses, enabling external protection schemes. This configuration supports precise coordination with upstream protection while avoiding unnecessary fuse maintenance and related downtime.
Yes. The unit comes in a NEMA 3R enclosure with painted galvanized steel, designed for outdoor and damp environments. UL Listed certification further supports safety compliance in varied conditions. Ensure proper installation clearances and enclosure access to maximize weather resistance and long-term reliability.
The DH165URKN carries UL Listed certification, confirming compliance with established safety standards for electrical equipment. It features a NEMA 3R enclosure suitable for outdoor use and damp environments, providing additional assurance for installations exposed to the elements. These certifications support regulatory alignment and risk mitigation in critical DC applications.
Maintenance considerations include minimal internal fuse maintenance due to non-fusible design and reduced wiring errors thanks to factory-installed neutral assemblies. The 110 lb, sturdy enclosure supports long service life in demanding environments. With a one-year warranty (or 18 months from shipment), customers can expect lower lifecycle costs and faster project turnover from easier installation and reduced downtime.
