Eaton DC disconnect DH161UWKN - UL Listed, 600VDC
Part Number: DH161UWKN
Quick Summary
Eaton DC disconnect is a rugged single-pole switch that safely isolates DC power in industrial automation and solar applications. Engineers often contend with corrosion, washdown exposure, and tight panel space when implementing DC control in harsh facilities. This model is UL Listed and housed in a NEMA 4X enclosure of 304 stainless steel, delivering excellent corrosion resistance and reliable performance. With neutral assemblies factory installed and a compact footprint, it streamlines wiring, accelerates panel assembly, and reduces on-site wiring errors. The device’s 30A rating, 600 VDC capability, and non-fusible configuration align with common DC control standards, supporting safer maintenance routines and predictable lifecycle costs for procurement and engineering teams.

FAQs
The DH161UWKN uses a single-pole, single-throw configuration with a 30A, 600 VDC rating and a non-fusible fuse arrangement. It fits in standard control panels with a 10.22 in depth, 8.76 in width, and 14.14 in height, and its 14.7 lb weight supports over-mounting or rack-based installations. Factory-installed neutral assemblies simplify wiring during panel assembly.
Key ratings include 30A amperage, 600 VDC voltage, single-pole, single-throw operation, and non-fusible fuse configuration. It is UL Listed and designed for use in NEMA 4X enclosures, making it suitable for DC distribution and control circuits in industrial environments.
Yes. The 600 VDC rating and 30A capacity, combined with a corrosion-resistant 304 stainless steel enclosure, make it well-suited for solar PV DC disconnect applications, including outdoor or washdown environments where robust protection and reliable isolation are required.
The DH161UWKN is UL Listed, indicating compliance with recognized safety standards. Its NEMA 4X enclosure and corrosion-resistant construction further ensure suitability for harsh environments, helping with procurement approvals and regulatory compliance for industrial installations.
Warranty is defined by Eaton’s policy 25-000 as one year from installation or eighteen months from shipment, whichever occurs first. Routine maintenance is typically limited to inspection and cleanliness of terminals; the non-fusible configuration reduces fuse-related maintenance, contributing to predictable lifecycle costs.
