A6X30138142 — same red selector in the 3SU1 family; identical specs except the trailing digit (142 vs 143). Both fit the same 22 mm round panel cutout and require separate contact blocks.
A6X30138144 — same functional role and enclosure rating; differing only in the trailing serial digits. Shares the same non-illuminated selector configuration and RoHS3 compliance.
A6X30138643 — same Siemens 3SU1 platform and selector function; differs by body color (black) and illumination capability, which adds an illumination-source requirement not present in the seed.

The body ships as a separate selector component; field assembly requires compatible Siemens 3SU1 contact blocks ordered independently. The I>O–II throw sequence corresponds to a three-position selector with center maintained.
Configuration Notes
- All 3SU1 body components require separate contact blocks (e.g., Siemens 3SU1□0AA10xx) for electrical operation — no contacts are integral to the actuator body.
- The non-illuminated red selector is typically used for machine E-stop reset or mode-select functions where color coding aids operator recognition.
- Panel cutout is 22.3 mm round; compatible with standard Siemens 22 mm operator-head mounting rings.
- RoHS3 compliance supports equipment destined for EU market end-of-life traceability requirements.
