Siemens SIRIUS ACT 3SU1051-3AB42-0AK0 Double Pushbutton Front Element, Metal, Red/Green

The Siemens SIRIUS ACT 3SU1051-3AB42-0AK0 is a professional-grade double pushbutton front element engineered for demanding industrial control environments. Constructed with a robust, high-gloss metal housing, this unit provides exceptional durability and a premium aesthetic suitable for modern control panels. It features distinct red and green actuators, allowing for intuitive and clear operational status indication, such as start and stop functions. As a core component of the Siemens SIRIUS ACT modular system, it ensures seamless integration, high reliability, and long-term performance in various automation setups.

Advantages

This double pushbutton offers superior mechanical resilience thanks to its high-quality metal construction, which withstands harsh industrial conditions and frequent operation. The modular design simplifies the assembly process, allowing for quick installation into standard 22mm mounting holes. Its ergonomic design ensures tactile feedback, while the clear color-coding provides immediate visual confirmation of the control state, reducing the risk of operator error in critical switching applications.

Suitable for

• Industrial automation control panels
• Machine start and stop operations
• Switchgear and distribution systems
• Human-machine interface (HMI) consoles

This device may not be suitable for environments requiring specialized explosion-proof ratings or specific chemical resistance beyond standard industrial specifications. It is also not intended for use in applications where a single-button interface is strictly required by safety protocols.

Key specifications

• Mounting diameter: 22mm
• Material: High-gloss metal
• Actuator colors: Red and Green
• System compatibility: SIRIUS ACT modular series
• Operational type: Double pushbutton

To install the front element, insert it into a standard 22mm hole on the control panel and secure it using the appropriate mounting hardware provided within the SIRIUS ACT system. Once the front element is fixed, attach the corresponding contact blocks to the rear side to complete the electrical circuit. Ensure that all connections are tightened according to the manufacturer's torque specifications to maintain the integrity of the installation.

What to consider before purchase

• Verify that your control panel has a 22mm mounting aperture.
• Ensure compatibility with your existing SIRIUS ACT contact blocks.
• Confirm the environmental conditions of your installation site.

For optimal performance and longevity, ensure the pushbutton is kept free of excessive dust or debris and perform periodic inspections of the mechanical movement to ensure smooth operation.
