## Long description

The Siemens SIRIUS ACT 3SU1051-0AB20-0AA0 is a professional-grade flat pushbutton actuator engineered for integration into industrial control systems. This component features a robust metal front ring and a distinct red finish, providing both visual clarity and mechanical durability. As part of the modular SIRIUS ACT series, it is designed to meet the rigorous demands of modern automation environments, ensuring consistent switching performance and long-term reliability.
Advantages
The primary benefit of this actuator lies in its high-quality construction, which includes a metal front ring that offers superior resistance to mechanical wear and environmental stressors. The flat design minimizes the risk of accidental activation while maintaining an ergonomic profile for operators. Furthermore, the modular nature of the SIRIUS ACT system allows for rapid assembly and flexible configuration, significantly reducing installation time and maintenance complexity in complex control panels.
Suitable for
Industrial control panels and automation systems
Emergency stop or command signaling applications
Machinery control interfaces
Environments requiring high ingress protection
This actuator may not be suitable for applications requiring non-standard mounting hole diameters or for environments where specific chemical resistance beyond standard industrial specifications is required. It is also not intended for use as a standalone switch without the necessary contact blocks and holders from the SIRIUS ACT series.
Key specifications
Actuator type: Flat pushbutton
Color: Red
Front ring material: Metal
Mounting diameter: 22 mm
Ingress protection: IP69K
Operation type: Momentary (spring-return)
To install the actuator, insert the component into the 22 mm mounting hole of the control panel and secure it using the appropriate SIRIUS ACT holder. Once the actuator is fixed in place, attach the required contact blocks to the rear of the assembly. Ensure that all connections are tightened according to the specified torque requirements to maintain the integrity of the enclosure.
What to consider before purchase
Verify that your control panel has a 22 mm mounting aperture
Ensure compatibility with existing SIRIUS ACT contact blocks and holders
Confirm the required switching logic (momentary vs. latching) for your application
Check environmental conditions to ensure the IP69K rating meets your operational needs
For optimal performance and longevity, ensure that the actuator is kept free of excessive debris and that the contact blocks are inspected periodically for signs of wear. Always follow the manufacturer's installation guidelines to maintain the IP69K protection rating.
