Siemens A6X30139414 Key-Operated Switch — 3SU1 Series Body
Catalog Identity and Product Class
The A6X30139414 is a Siemens keylock switch body from the 3SU1 family, designed for 22mm round panel cutout mounting. It ships as a non-illuminated, box-encapsulated unit classified under Configurable Switch Bodies and requires separate contact block(s) for completion. The unit is ROHS3 Compliant with an Active product status.
Key Selection Trade-offs (3SU1 Keylock Bodies)
-
Switch position sequence: The A6X30139414 carries the CES key-lock designation with an I>O-II position sequence. Alternates within this catalog group use O.M.R. (A6X30139464, A6X30139491, A6X30139490, A6X30139614, A6X30139204) or RONIS (A6X30139014, A6X30139119, A6X30139141) lock families, each offering different key-removal points and mechanical throw. Position sequence must match the safety circuit or mode-select logic intended.
-
Key-lock family vs. key management policy: CES, O.M.R., and RONIS are distinct key-lock mechanisms. Within the same 22mm form factor, each family may impose different key insertion/removal constraints. If multiple operators share a key stock, confirm that the chosen family aligns with existing key-management conventions on site.
-
Contact block assembly required: This body is a partial assembly — it does not include contact blocks. The completed switching function depends on selecting compatible contact block(s) from the Siemens 3SU1 contact block line. Ensure auxiliary contact configuration (NC/NO count, early-break/late-break) is resolved before panel wiring.
-
Non-illuminated design: The A6X30139414 is non-illuminated, which simplifies the panel wiring but removes any visual status indication. If an illuminated status is needed for a given operator position, a different body variant must be selected from the 3SU1 illuminated range.
-
Panel cutout and mounting: All catalog entries for this comparison share the 22.3mm round cutout dimension. This implies common hardware and mounting ring selection across the peer group, but the panel builder should verify that the selected body does not conflict with adjacent 22mm devices in the same enclosure row.

Why These Parts Are Catalog-Similar
All nine MPNs share identical values for: Siemens brand, 22mm compatible series, keylock actuator type, box encapsulation, non-illuminated function, 22.3mm round panel cutout, box package, active status, ROHS3 compliance, and the requirement for separate contact blocks. Differences are confined to the key-lock mechanism family (CES vs O.M.R. vs RONIS) and the mechanical position sequence — parameters that govern how the operator physically interfaces with the device and at which angular positions contacts open or close. The O.M.R. alternates (A6X30139464, A6X30139491, A6X30139490) score 0.96 because they share the same 9-character MPN prefix as the primary; RONIS variants score 0.92 with an 8-character shared prefix.
FAQ
Q: What contact blocks are compatible with the A6X30139414? A: The A6X30139414 is listed as requiring contact block(s) from the Siemens 3SU1 series. Specific block part numbers, NC/NO counts, and electrical ratings are not supplied in this catalog record.
Q: Can the A6X30139414 be used as a drop-in replacement for an O.M.R. keylock body? A: The A6X30139414 and O.M.R. alternates share the same 22mm form factor, panel cutout, and contact block interface. However, the key-lock family (CES vs O.M.R.) differs, which affects the key insertion/removal angular positions. Reader qualification is required before substitution.
Q: Is the A6X30139414 available in an illuminated version? A: The A6X30139414 is cataloged as non-illuminated. Illuminated variants would carry different MPNs and are not listed as alternates in this catalog group.
