The Siemens 3SU1051-1BA20-0AA0 is a premium, high-visibility control component from the SIRIUS ACT portfolio, designed for robust industrial environments. This illuminated mushroom-head pushbutton features a substantial 40 mm diameter head, making it highly conspicuous and easy to operate. Crafted with a shiny, high-quality metal front ring, it ensures maximum durability and a professional aesthetic for control panels.
Designed for standard 22 mm mounting cutout applications, the red color and illumination (requires separate LED element) provide immediate visual feedback on the control's status. It features a reliable latching function, meaning the button remains depressed until manually reset via the pull-to-unlatch mechanism. This makes the 3SU1051-1BA20-0AA0 ideal for applications requiring continuous or sustained machine stop/start, mode selection, or critical process holds.
Superior Visibility: The illuminated, large 40 mm red head ensures operators can quickly locate and actuate the control, reducing response time.
Industrial Durability: Features a robust metal, shiny front ring that withstands harsh industrial conditions, ensuring a long operational lifespan.
Reliable Latching: The secure latching mechanism guarantees the control status remains constant until manually reset, crucial for safety and process integrity.
Easy Reset: The intuitive pull-to-unlatch mechanism allows for simple and rapid resetting of the button after actuation.
Modular SIRIUS ACT: Integrates seamlessly with the flexible SIRIUS ACT system, allowing easy installation and combination with necessary contact and LED elements.
