Siemens A6X30137335 — Illuminated E-Stop Pushbutton (3SU1 Series)
Selection Trade-offs for A6X30137335 and 3SU1 E-Stop Variants
-
Actuator head size: The primary A6X30137335 uses a round mushroom E-Stop actuator, while in-catalog peers A6X30137330, A6X30137338, A6X30137339, A6X30137315, and A6X30137395 list mushroom pushbutton actuators in 30mm or 40mm diameters. The mushroom profile affects tactile engagement area and emergency-actuation ergonomics.
-
Illumination integration: All listed parts are Illuminated. The A6X30137335 requires an Illumination Source in addition to Contact Block(s) — the light element is not integral to the switch body. This adds a line item to the bill of materials compared to non-illuminated 3SU1 operators.
-
Panel cutout compatibility: All catalog entries specify 22.3mm (Round) panel cutout and Siemens 22mm compatible series. This is standard for 3SU1 modular operators and interfaces with standard Siemens guide rings and bezels.
-
Modular assembly requirement: Each body requires Contact Block(s) and an Illumination Source to become a functional branch device. These are ordered separately under the 3SU1 system; the operator body alone does not form a complete switch.

Why the Similar Entries Differ
- A6X30137337: Shares E-Stop, Round actuator type with A6X30137335. The MPN suffix suggests a color or legend variant within the same illuminated E-Stop family.
- A6X30137338 and A6X30137339: Use Pushbutton, Mushroom actuators instead of E-Stop. These suit general start/stop or mode-selection roles rather than emergency stop functions; they retain the same 22mm panel footprint, illumination sourcing, and 3SU1 compatibility.
All nine in-catalog MPNs share Siemens 3SU1 series membership, illuminated function, box encapsulation, and identical panel cutout dimensions. The primary differentiators are actuator style (E-Stop vs. mushroom pushbutton) and head diameter where specified.
FAQ
What does the A6X30137335 require to become a functional switch? It is a configurable switch body that requires separately ordered Contact Block(s) and an Illumination Source. The operator body alone does not constitute a complete switching device.
Is the A6X30137335 an emergency stop operator? Yes. The actuator type is listed as E-Stop, Round, distinguishing it from mushroom pushbutton variants in the same series that carry a general start/stop or selector function.
What panel cutout does A6X30137335 need? The specified panel cutout is 22.3mm round, compatible with the Siemens 22mm series standard for 3SU1 modular operators.
