Siemens A6X30143681 Illuminated Pushbutton
Engineering verification checklist
- Confirm illumination voltage matches supply: 230 VAC nominal
- Verify contact block rating and configuration for the target circuit
- Check panel cutout and bezel clearance for 22mm mounting hole
- Validate IP69K gasket orientation and tightening torque for watertight seal
- Confirm 10A SPST-NO rating is appropriate for the load type (AC/DC)
- Verify LED polarity and supply compatibility if using DC illumination
- Check that contact block and any required adapters are ordered separately
- Confirm illumination module is included or must be added as a separate line item
A6X30143681 specifications and construction
The A6X30143681 is a self-contained illuminated pushbutton in the Siemens 3SU1 series, incorporating a green LED module rated for 230 VAC. The actuator is a round, non-illuminated-style button in green, with illumination provided via an integrated LED source. This unit ships as a complete assembly; it requires contact block(s) and may require an adapter depending on the selected mounting depth.
Key ratings and operating envelope
| Parameter | Value |
|---|---|
| Circuit | SPST-NO |
| Current rating | 10A AC/DC |
| Mechanical life | 3,000,000 cycles |
| Electrical life | 10,000,000 cycles |
| Illumination | LED, 230 VAC nominal |
| IP rating | IP66 / IP67 / IP69K |
| Mounting | Panel mount, front, 22mm bezel |
Environmental and mechanical notes
The IP69K rating makes this suitable for high-pressure washdown environments typical in food, pharmaceutical, and chemical processing. The 22mm standard cutout is consistent with industrial control panel conventions. The high cycle ratings support demanding applications where frequent actuation occurs, such as HMI interfaces or process control stations.
Alternate comparison
The LED module A6X30143984 shares the 3SU1 series and 230 VAC green illumination type with the seed unit. The remaining alternates (A6X30143921, A6X30143861, A6X30143941, A6X30140681, A6X30143924, A6X30143915, A6X30143836) are non-illuminated pushbutton bodies requiring contact blocks; they share the 3SU1 series and 22mm panel cutout but lack the integrated LED illumination.
| MPN | Color | Illumination | Circuit |
|---|---|---|---|
| A6X30143681 | Green | LED, 230 VAC | SPST-NO |
| A6X30143984 | Green | LED, 230 VAC | — (module only) |
The A6X30143984 is a replacement or spare LED module compatible with the 3SU1 illuminated pushbutton platform. It shares the same green color and voltage, serving as a service part for the illumination subassembly.
