HD11F Single Throw Anti-Error Knife Switch

The HD11F Single Throw Anti-Error Knife Switch provides reliable isolation for industrial power systems, supporting 200A-1600A loads at AC380V/DC220V with 660V insulation. Engineered for safety, this anti-error knife switch features a single-throw design to prevent misoperation, alongside high short-time withstand currents (10-32kA for 1s). With 10,000-cycle mechanical endurance and low operating force (≤450N), the HD11F switch ensures effortless manual control in harsh environments. Compliant with AC-20 standards and 50Hz frequency, it is ideal for distribution panels and machinery requiring fail-safe disconnection and durable performance.
