Siemens A6X30140662 Pushbutton Operator Body (Green, Non-Illuminated)
Overview
The A6X30140662 is a Siemens 3SU1 series round pushbutton operator body designed for 22mm industrial panel cutouts. It occupies the human-machine interface layer of a control circuit—mechanical actuation only, with no integral contacts or lighting. The device requires separate contact blocks to complete an electrical switching function. According to the catalog fields, the unit is active, ROHS3 compliant, and packaged individually in a box. Electrical ratings (voltage, current, thermal class, IP front-face) are not supplied in the source data; these must be obtained from the official Siemens datasheet before any selection decision.
Verification required — do not proceed on electrical ratings alone. The catalog fields do not include: maximum switching voltage, maximum switching current, making/breaking capacity, IEC947 / EN60947 ratings, temperature range, IP front-face rating, or mechanical endurance cycles. Confirm these against the Siemens 3SU1 datasheet.

Family Context (Ordering Code / 3SU1 Series)
The "A6X" prefix in Siemens ordering codes denotes a specific operator color and type within the 3SU1 series. The 3SU1 family is Siemens' modular 22mm pushbutton and indicator line, where the actuator operator body (front element) is always ordered separately from the contact block (side-attached element) and any illumination module. This modularity means the operator body alone cannot switch a circuit; a contact block must be selected and assembled. The "40662" portion of the code encodes color and variant information. This decode is based on Siemens standard ordering-code conventions; verify against the official 3SU1 catalog for exact mapping.
Integration and Installation Notes
The device is designed for a 22.3mm round panel cutout in a standard 22mm mounting hole. Because it is non-illuminated, no separate lamp or LED module needs to be accommodated behind the panel. The round actuator head style implies a common mounting footprint for the 3SU1 series.
Installation considerations not specified in supplied fields:
- Required panel thickness or bezel depth
- IP rating at the front face (depends on seal selection)
- Specific compatible contact block MPNs
- Terminal type (screw, spring-clamp, cage-clamp) — determined by the contact block, not this unit
The contact block selection is critical: it defines the electrical function (normally-open, normally-closed, early-make, late-break, etc.) and the rated current/voltage of the final assembly.
Selection and Substitution Notes
The A6X30140662 is the green variant of the 3SU1 round pushbutton operator body. Color variants exist in black, red, yellow, blue, and clear — each a distinct MPN in this series. Substituting a different color MPN does not change the electrical or mechanical interface but does affect the operator's visual status meaning in a control scheme (e.g., green = start/go, red = stop/emergency, yellow = caution/interlock).
All MPNs in this series share the same: actuator type, series, illumination type, cutout dimensions, encapsulation, and requirement for contact blocks. Electrical ratings and compatibility with specific contact block families should be confirmed cross-device before cross-referencing any alternative.
Similar Catalog Parts
All alternates share identical specifications on: actuator type, series, illumination type, encapsulation, compatible series, panel cutout, and requirement for contact blocks. The sole differentiator is the button color.

Why A6X30140669 (Blue, similarity 1.0): Identical MPN prefix length (10 characters), near-perfect edit-distance match, and every spec key is shared. Same 3SU1 series, same panel cutout, same requirement for contact blocks. Only the operator color differs.
Why A6X30140660 (Yellow, similarity 1.0): Matches A6X30140669 in structure and spec coverage. Yellow is frequently used for caution or interlock status indication. Verify the intended color coding convention for the specific application before selection.
Why A6X30140682 (Green, similarity 0.96): Shares all spec keys and series. The slightly lower similarity reflects a 9-character MPN prefix rather than 10 characters. No spec difference is present in the shared fields; the delta is in the ordering-code structure only.
FAQ
Q: Does the A6X30140662 include a contact block? A: No. The catalog explicitly lists "Requires: Contact Block(s)". The operator body alone provides mechanical actuation only. A compatible Siemens contact block (e.g., 3SU1 5□-1AD00-0AA0 style) must be ordered separately and assembled to create a functional switch.
Q: What is the panel cutout size for the A6X30140662? A: The catalog specifies a 22.3mm round cutout, consistent with the 22mm nominal mounting size of the Siemens 3SU1 series. Verify bezel or seal requirements against the datasheet.
Q: Is the A6X30140662 suitable for safety-related applications (SIL/PL)? A: The supplied catalog fields do not include safety integrity parameters (SIL, PL, B10d, mission time). Safety-function switching requires a validated contact block and a documented system-level assessment. Consult the Siemens 3SU1 system documentation and relevant functional safety standards before applying this component in a safety circuit.
