Eaton Specification Sheet - DH366UGKNLPR
The DH366UGKNLPR is rated for 600A at 600V across three poles, delivering reliable high-current protection for large motor loads and critical feeders. This translates to fewer parallel switches and streamlined protection coordination in manufacturing lines, reducing commissioning time and risk of overload. The Posi-Lok reverse pin design ensures secure engagement and correct alignment during installation, which minimizes mis-wiring and field adjustment costs while improving overall safety during maintenance. With a Series K, NEMA 1 indoor enclosure, the switch withstands routine industrial environments and simplifies cabinet integration, enabling faster installation in existing panels and new installations alike. Unfused configuration keeps system design straightforward and cost-effective, provided upstream overcurrent protection is properly specified. UL Listed certification supports regulatory compliance, and the one-year warranty aligns with Eaton’s policy, offering peace of mind for mission-critical applications. The large footprint—32.87 in long, 74.34 in high, 16.1 in wide, and 370 lb—factors into site planning, but yields a durable, long-life solution suitable for demanding facilities. Overall, the DH366UGKNLPR helps manufacturers reduce downtime, improve safety, and meet compliance goals while remaining compatible with Eaton distribution ecosystems and service resources.
