Siemens A6X30142772 — Illuminated Green Pushbutton (3SU1 Series)
The A6X prefix identifies this as a Siemens 22mm modular operator component within the 3SU1 operator series. The record lists it as a front-panel-mounting illuminated pushbutton combining a DPST-NO/NC contact block with an integrated green LED rated for 110 VAC nominal supply.
Engineering verification checklist
- Confirm control circuit voltage matches 110 VAC illumination rating
- Verify DPST-NO/NC contact arrangement satisfies load switching requirements (10A AC/DC)
- Check enclosure or cabinet depth available for front-panel mounting
- Confirm panel cutout is compatible with 22.3mm round dimension for the series
- Verify IP66/IP67/IP69K sealing is appropriate for the installation environment
- Coordinate LED drive: 110 VAC requires either direct connection or compatible bus/driver module if illumination is externally sourced
- Confirm electrical life of 10,000,000 cycles meets expected switching frequency over equipment lifecycle
- Mechanical life 3,000,000 cycles applies to actuator travel; confirm no mechanical override usage conflicts

Integration notes
The IP66/IP67/IP69K rating positions this for washdown or outdoor industrial environments. The front-panel mounting style suits enclosure doors or operator stations where the panel seal must be maintained around the actuator perimeter.
Contact configuration DPST-NO/NC provides one normally-open and one normally-closed pole within a single device — useful for interlocking or sequencing logic without requiring a separate auxiliary contact block.
The 10A current rating covers both AC and DC loads, though coordination with upstream protective devices should account for DC breaking characteristics if DC loads are intended.

Why A6X30163097 is similar: Shares the same Siemens 3SU1 series family and box packaging, with a contact block designed to snap onto compatible operator bodies in the same modular system. The circuit is SPST-NC rather than DPST-NO/NC, providing a normally-closed pole only.
Why A6X30140742 is similar: Belongs to the same 22mm Siemens 3SU1 series as other mushroom-head variants in the catalog; shares box encapsulation and is a configurable switch body requiring separate contact blocks. Actuator type differs (mushroom vs round button) and it is non-illuminated, so it does not cover the same visual-indication function.
No catalog-listed alternates provide a direct illuminated-green drop-in with identical electrical and sealing ratings; selection should remain with A6X30142772 for applications requiring the integrated LED + contact combination.
FAQ
What illumination voltage does A6X30142772 require? Nominal illumination voltage is 110 VAC. Verify control circuit compatibility before wiring.
Does A6X30142772 include the contact block or is it sold separately? The title reflects an assembled illuminated pushbutton combining both the operator and contact function (DPST-NO/NC). Confirm ordering configuration if a modular or body-only variant is required.
Is the LED in A6X30142772 replaceable? The record does not specify field-replaceable LED modules. Consult Siemens 3SU1 series documentation for serviceability and part availability.
