Siemens A6X30142988 — Blue Round Pushbutton Switch (3SU1 Series)
Catalog peer comparison
All entries below share the same brand, series family, and box packaging. The seed switch is a complete, ready-to-install actuator head; each comparable row represents a modular body that requires separate contact blocks.
| Part number | Type | Color | Illumination | Compatible series |
|---|---|---|---|---|
| A6X30142988 | Pushbutton, round (seed) | Blue | Non-illuminated | — |
| A6X30140688 | Pushbutton, round | Blue | Non-illuminated | Siemens, 22mm |
| A6X30140588 | Pushbutton, round | Yellow | Non-illuminated | Siemens, 22mm |
| A6X30140986 | Pushbutton, round | Yellow | Illuminated | Siemens, 22mm |
The comparable pushbutton bodies (A6X30140688, A6X30140588) carry identical actuator and illumination attributes; they differ by cap color and reference the same 22mm panel cutout standard. The yellow variants allow differentiation for logic-level indication without sourcing an additional illumination source.
The seed unit and the 22mm body family both require contact blocks for electrical switching function — a standard architectural constraint of the Siemens 3SU1 configurator system.
Key specifications
| Parameter | Value |
|---|---|
| Circuit configuration | SPST-NO |
| Current rating | 10 A (AC/DC) |
| Electrical life | 10,000,000 cycles |
| Mechanical life | 10,000,000 cycles |
| Actuator type | Round, button |
| Cap color | Blue |
| Mounting | Panel mount, front |
| Panel cutout | 22.3 mm (round) |
| Ingress protection | IP66 / IP67 / IP69K |
| Operating temperature | −25 °C to +70 °C |
| Package | Box |
The IP69K rating permits high-pressure/steam washdown, positioning this actuator for food-processing, pharmaceutical, or outdoor industrial enclosures where chemical washdown is routine.
Installation notes
The seed part ships as a complete actuator head. Field assembly into a Siemens 3SU1 front-mount collar is standard; the 22.3mm round cutout aligns with the family dimension evident across comparable rows. Contact blocks (separate line items) attach to the rear sleeve to complete the switching circuit.
No auxiliary contact arrangement is embedded in this part — coordination with downstream branch-protection devices remains a system-level design task.
In-catalog alternatives with different color or illumination
| Part number | Color | Illumination |
|---|---|---|
| A6X30140688 | Blue | Non-illuminated |
| A6X30140588 | Yellow | Non-illuminated |
| A6X30140986 | Yellow | Illuminated |
| A6X30140984 | Red | Illuminated |
| A6X30141188 | Black | Non-illuminated |
| A6X30140288 | White | Illuminated (selector) |
Selector switches and illuminated variants require additional components (illumination sources, multi-position mechanisms) — they are not drop-in replacements for a non-illuminated pushbutton head.
FAQ
Does the A6X30142988 ship with contact blocks? No. The part is the actuator head only. A compatible Siemens contact block (rated for the applied voltage and current) must be ordered separately.
What panel cutout is required? Comparable family members list a 22.3 mm round cutout. Confirm with the specific collar or bezel ordered, as 30mm variants exist in the same series.
Is the A6X30142988 suitable for outdoor or washdown environments? The IP66/IP67/IP69K rating covers dust-tight and high-pressure water exposure, including steam cleaning, which supports outdoor and hygienic-area deployments.
