Eaton DH366UGKSNLPR Heavy Duty Safety Switch - 600A
Part Number: DH366UGKSNLPR
Quick Summary
Eaton DH366UGKSNLPR heavy duty safety switch provides reliable line-side isolation for industrial power distribution in harsh environments, protecting personnel and enabling safe maintenance in demanding facilities such as manufacturing lines and data centers. When downtime matters, complex wiring and unfused configurations slow fault isolation and raise safety risk; the design reduces mis-wiring, simplifies cabinet layouts, and supports fast lockout/tagout procedures across multiple work shifts. UL Listed certification supports compliance with safety standards for industrial control gear, enabling easier vendor qualification and safer procurement, while suitability for Series K and NEMA 1 enclosures ensures durable protection in dusty or humid environments. Together with its 600A rating, 600V capability, three-pole configuration, and unfused design, this switch minimizes spare parts and accelerates installation in control panels and switchgear assemblies.
