The oval dual form factor and white/black color distinguish A6X30136638 from the round, mushroom, and key variants. A6X30136639 matches identically on actuator style and color. A6X30136698 and A6X30136699 introduce illumination and round geometry—a different installation profile.
Contact Block and Illumination Sourcing
The body is a bare actuator sub-assembly; panel builders must source contact blocks separately. The 3SU1 series supports standard single- and double-block configurations with silver alloy contacts rated for low-voltage control circuits. For illuminated variants (A6X30136698/A6X30136699), an additional illumination element and wiring provision are required. The dual oval geometry may affect clearance spacing in dense control modules—verify block depth and actuator travel against enclosure layout.
RoHS and Compatibility Notes
All listed 3SU1 variants carry ROHS3 compliance. The 22.3mm round cutout accepts the full 3SU1 front ring and adapter lineup. The dual oval head does not interchange mechanically with round or mushroom adapters; use only Siemens 3SU1-specific mounting hardware for this part.
