Siemens A6X30138630 — 3SU1 Blue Pushbutton Operator Body
Overview
The A6X30138630 is the Siemens 22mm pushbutton operator body from the 3SU1 series. The A6X prefix designates this as a SIRIUS 3SU1 configurables operator component; the numeric suffix follows Siemens ordering conventions for actuator color and type within that series. The unit is non-illuminated and requires separate contact block(s) to complete a functional switch assembly.

Selection Trade-offs
- A6X30138630 vs. illuminated variants — This unit lacks an integrated illumination source; if pilot-light feedback is required, consider parts with "Illuminated" in the title or spec (e.g., A6X30138610).
- Pushbutton vs. selector type — The round pushbutton actuator serves momentary or latching two-position logic; selector variants (A6X30138637, A6X30138634, A6X30138638, A6X30138632, A6X30138690, A6X30138680) provide maintained O-I or multi-position switching.
- Color coding — The blue actuator carries conventional meaning in industrial safety systems; yellow (A6X30138600) and white/red options exist within the same series footprint for differentiated panel zones.
- Contact block sourcing — Both the pushbutton and selector variants require Siemens 3SU1 contact blocks; matching the block type (NO/NC, spring-type vs. screw-type) to the circuit function is the installer's responsibility.
Similar Catalog Parts
| MPN | Title | Actuator Type | Similarity |
|---|---|---|---|
| A6X30138637 | SELECTOR SWITCH. O-I. WHITE | Selector | 0.928 |
| A6X30138634 | SELECTOR SWITCH. O-I. WHITE | Selector | 0.928 |
| A6X30138638 | SELECTOR SWITCH. O-I. WHITE | Selector | 0.928 |
These selector switches share the same 3SU1 series, 22.3mm panel cutout, box packaging, and non-illuminated configuration as the primary part. The key difference is the actuator type (selector maintained positions versus pushbutton momentary).
Other in-catalog alternatives include red and blue selector switches (A6X30138632, A6X30138690), a yellow pushbutton (A6X30138600), and an illuminated dual pushbutton (A6X30138610) — all sharing the same Siemens 22mm form factor but differing in actuator color or illumination.
