Eaton DH366UGKSNLP Heavy-Duty Safety Switch - UL Listed
Part Number: DH366UGKSNLP
Quick Summary
Eaton DH366UGKSNLP is a heavy-duty safety switch built for reliable disconnect in electrical control panels and industrial facilities. Maintenance and commissioning teams often struggle with bulky enclosures, tangled wiring, and inconsistent lockout procedures during service. UL Listed certification ensures compliance with electrical safety standards, while a NEMA 1 enclosure protects against dust and indoor contaminants in typical panel environments. For engineers and procurement teams, the combination of Series K design, Pos-Lok locking, and a 600A/600V rating translates to faster panel integration, reduced downtime, and a stronger ROI. This model also aligns with standard installation practices to simplify retrofits and spare-part availability.
