Eaton DH364NRKLLV Auxiliary Power Switch - UL Listed
Part Number: DH364NRKLLV
Quick Summary
Eaton auxiliary power switch reliably controls three-phase power in industrial panels and switchgear. Operators and maintenance teams often struggle with mislabeling, slow fault isolation, and weather exposure that drive downtime. UL Listed and built in a rugged NEMA 3R enclosure with a Class H fuse provision help ensure code compliance and outdoor performance. Three-pole, four-wire configuration and fusible-with-neutral design support safe, predictable operation across large feeders. Coupled with the K-Series design, this solution delivers robust protection and straightforward compatibility for Cu/Al conductors up to #6-250 kcmil, reducing spare parts and installation time. This translates to faster commissioning, easier maintenance, and improved system uptime in demanding environments.

FAQs
The DH364NRKLLV supports a three-pole, four-wire configuration rated at 200A and 600V, with fusible protection that includes a neutral. It accepts Cu/Al conductors from #6 to 250 kcmil, making it suitable for motor control centers, main distribution panels, and outdoor feeder connections. This compatibility simplifies panel design and reduces stock complexity for large facilities.
This unit uses a NEMA 3R enclosure with painted galvanized steel, delivering weather resistance for outdoor or harsh indoor environments. Plan for proper mounting clearances, secure enclosure grounding, and correct labeling of line/load terminals. The unit weighs about 52 lb, so use appropriate lifting methods and check for compatibility with nearby devices in the K-Series family.
The DH364NRKLLV is UL Listed, ensuring compliance with recognized electrical safety standards for industrial switchgear. Its NEMA 3R enclosure supports outdoor conditions, and the device uses Class H fusing to meet safety and reliability expectations. This combination supports code compliance in commercial and industrial installations where safety certifications are a requirement.
Enhanced visible blades and line/load labeling accelerate fault finding and routine maintenance, lowering downtime. The fusible-with-neutral design and Class H fuse provide predictable protection, helping to minimize unplanned outages. Its robust construction and Cu/Al conductor compatibility reduce spare-part variety and replacement costs, contributing to lower total cost of ownership over time.
Ideal for motor control centers, outdoor substations, and heavy-duty power distribution in manufacturing and processing facilities. The three-pole, four-wire configuration supports three-phase loads up to 200A at 600V, while the NEMA 3R enclosure enables reliable performance in exposed environments. Use in new builds or retrofit projects that require rugged protection and code-compliant safety switching.
