Backorder available · Factory lead time 2–3 weeks.
The Siemens 3SU1052-2BL40-0AA0 is a premium component from the SIRIUS ACT portfolio, specifically engineered for demanding industrial environments. This 22 mm panel-mount selector switch features a durable metal, shiny, high-gloss bezel and an eye-catching green color, ensuring both longevity and visibility. It is an illuminable type, which is crucial for operational feedback on complex machinery. The mechanism is a short, 3-position, latching (maintained) switch with clear I-O-II markings, making it ideal for selecting between three operating states (e.g., Manual-Off-Automatic, Low-Off-High).
Exceptional Durability: Robust metal construction provides maximum resistance against mechanical stress in harsh industrial settings.
High Visibility: The green, illuminable design ensures the switch position is clearly visible, improving operator safety and reducing errors.
Reliable Operation: Latching (maintained) function ensures the selected position remains stable, preventing unintended switching and simplifying control logic.
Aesthetically Pleasing: The shiny, round metal bezel gives control panels a modern, high-quality professional look.
Industry Standard: Part of the widely adopted Siemens SIRIUS ACT series, guaranteeing compatibility and ease of integration.
