Backorder available · Factory lead time 2–3 weeks.
The Siemens 3SU1051-0AA20-0AA0 is a high-performance illuminated pushbutton operator from the SIRIUS ACT series, designed for reliable switching and control in demanding industrial environments. This 22 mm round actuator features a sleek, shiny metal front ring and a bright red, flat button. It utilizes a latching (maintained) function, which is released by a push-to-release mechanism, making it ideal for critical stop or maintained-state control applications. Part of the robust metal design line, this component ensures long-term operational integrity.
Product Brand Name: SIRIUS ACT
Product Type Designation: 3SU1
Mounting Diameter: 22.3 mm (Round)
Actuating Element: Flat Button, Red, Plastic
Front Ring: Metal, High Gloss, Silver
Operation: Latching (Maintained) with Push-to-Unlatch Mechanism
Exceptional Durability: Features a robust metal front ring and high IP protection ratings (IP66, IP67, IP69K), ensuring resistance to dust, oil, and high-pressure jet cleaning, making it suitable for harsh environments.
High Reliability: Offers a long mechanical service life of typically 500,000 operating cycles, minimizing maintenance and downtime.
Easy, Fast Installation: The innovative SIRIUS ACT snap-on concept allows for quick, one-handed installation without specialized tools, saving valuable assembly time. Twist prevention is integrated directly into the holder design.
Flexible Integration: As an operator/actuating element, it is fully compatible with the modular SIRIUS ACT system, allowing for flexible combination with contact modules and LED modules (sold separately) to meet specific control requirements.
This component functions as the front operating element for a control station. When pushed, the internal contact module (not included) latches, maintaining the switched state. The state is only reset (released/unlatched) by pushing the button a second time (Push-to-Release/Push-to-Unlatch mechanism). The illumination feature (requires a separate LED module) provides clear visual feedback on the switch status, enhancing operator safety and efficiency.
