FAQs
For 600 VDC systems, ensure mounting in a compatible enclosure space with proper clearance for the 11.26 in depth. The unit weighs 46 lb, so use a two-person lift if needed. Verify alignment with the NEMA 3R outdoor rating and confirm that the neutral assemblies are factory-installed to minimize on-site wiring tasks. Use appropriate lugs and torque specifications per Eaton’s datasheet to maintain a safe, compliant installation.
Yes. The DH164URKN is designed for outdoor use in 600 VDC solar PV applications, featuring a NEMA 3R enclosure and painted galvanized steel for weather resistance. It is UL Listed, providing regulatory confidence for outdoor DC isolation in solar farms, rooftop arrays, and other renewable-energy installations.
Key ratings include 200 A amperage, 1 circuit, single-pole, non-fusible, with a 600 VDC voltage rating. The enclosure is NEMA 3R and the device is UL Listed. These features collectively support safe, reliable isolation for high-current DC power paths while meeting standard electrical protection requirements.
Factory-installed neutral assemblies reduce on-site wiring labor, minimize miswiring risks, and streamline integration with control circuits. This leads to faster commissioning, easier future modifications, and improved overall system reliability—especially valuable in complex DC power distributions and retrofit projects.
The DH164URKN is UL Listed, offering established safety certification. Eaton’s warranty policy 25-000 applies, providing one year from installation or eighteen months from shipment, whichever occurs first. For ongoing support, consult Eaton’s technical documents and the specification sheet (DH164URKN) to plan maintenance and ensure long-term compliance.
