Overview
The Siemens A6X30138444 is a red illuminated pushbutton actuator body from the 3SU1 series, designed for 22mm panel cutout installations. This component ships as a configurable body only—it requires separate contact block(s) and an illumination source to become functional. The round actuator is housed in a box-style encapsulation, and the assembly carries ROHS3 Compliant status.
The 3SU1 series represents Siemens' standardized 22mm industrial operator interface platform. These bodies accept modular contact blocks and lamp/LED elements that snap or screw onto the rear of the actuator, enabling field-customizable NO/NC configurations and illumination colors.
Catalog Comparison: 3SU1 Illuminated Variants
The table below shows the A6X30138444 alongside in-catalog comparison rows sharing the same series, panel cutout, and actuator type. All parts require contact blocks; illuminated variants additionally require an illumination source.
| Part Number | Color | Illumination | Requires |
|---|---|---|---|
| A6X30138444 | Red | Illuminated | Contact Block(s), Illumination Source |
| A6X30138447 | Red | Illuminated | Contact Block(s), Illumination Source |
| A6X30138441 | Amber | Illuminated | Contact Block(s), Illumination Source |
| A6X30138464 | White | Illuminated | Contact Block(s), Illumination Source |
Why these parts are similar
- All four belong to the Siemens 3SU1 series and share the same 22.3mm round panel cutout and round pushbutton form factor.
- The A6X30138447 differs only in color; it uses the identical red lens designation but otherwise identical specifications.
- The A6X30138441 and A6X30138464 are color variants within the same illuminated actuator family, differing only in lens color while sharing all other cataloged parameters.
- Illumination status is the primary distinction against non-illuminated 3SU1 bodies, which omit the illumination source requirement entirely.
Selection Notes
- Color variant selection is driven by user-interface or status-indication requirements; all illuminated variants share the same mechanical interface.
- Illuminated vs. non-illuminated variants in the 3SU1 family carry different accessory requirements—plan contact block and lamp/LED element sourcing accordingly.
- Panel cutout and actuator type are consistent across the 3SU1 series, allowing mixed operator types in adjacent cutouts without layout changes.
FAQ
What accessories does the A6X30138444 require to function? It requires at least one contact block (NO, NC, or combination) and an illumination source (lamp or LED element) compatible with the 3SU1 series.
Can the A6X30138444 be used in the same panel cutout as other 3SU1 operators? Yes. All 3SU1 operators share a 22.3mm round cutout and can be installed in standard 22mm operator stations.
What is the difference between A6X30138444 and A6X30138447? Both are red illuminated pushbutton bodies with identical cataloged specifications; the MPN difference reflects internal ordering or lot variation within the same product.
