Product details

Blue Pushbutton for Industrial Control Interfaces

The A6X30142988 delivers a momentary (off-mom) SPST-NO contact arrangement in the Siemens 3SU1 series, targeting 22mm panel cutout designs where dust-tight and waterproof sealing is mandatory. Screw terminals accept rigid or flexible conductors without special tooling.

On-page parameter snapshot

Circuit: SPST-NO (momentary)
Voltage rating: 500V AC / 500V DC
Current rating: 10A AC/DC
Panel cutout: Circular 22.30mm dia
Actuator color: Blue
Termination: Screw terminal
Operating temperature: 25°C to 70°C

Selection Considerations

Momentary function suits start/stop or acknowledge pushbutton roles; pair with contact blocks for load switching.
IP66/IP67/IP69K sealing permits high-pressure washdown and temporary submersion—specify where hygiene or weather exposure is present.
22.30mm cutout aligns with common 22mm industrial pushbutton footprints; verify enclosure thickness before mounting.
Both electrical and mechanical life are 10,000,000 cycles, reducing replacement frequency in high-cycle applications.
Standard type designation indicates compatibility with standard Siemens 3SU1 contact blocks and accessories.

Procurement Notes

Lead time and MOQ require RFQ confirmation. ROHS3 Compliant status supports EU industrial equipment builds. The unit ships as a single box packaging.

Bench engineer's notes from raw specs

Treat the raw specification table as authoritative for siemens A6X30142988 (PUSHBUTTON. BLUE); category path: Switches > Pushbutton Switches; confirmed specs: series: 3SU1; Type: Standard; Mounting Type: Panel Mount, Front; Package: Box; Product Status: Active. Cross-check electrical limits, mounting style, output type, and lifecycle status against the target panel or machine design before signing off a drop-in.

Commissioning field notes

Before energizing or replacing the module, align cabinet power rails, wiring plan, load type, terminal layout, and temperature class with both the manufacturer documentation and the as-built BOM.

Selection notes — BOM and electrical class

Approve this line only when MPN, manufacturer, series, supply voltage, I/O style, mounting, and application role match the design intent. For alternates, diff the same fields first, then validate software/project hooks.

Engineering notes

IP66/IP67/IP69K allows steam-jet cleaning in food/beverage or pharmaceutical panels without specifying a separate waterproof enclosure.

10M cycle life suits high-frequency start-stop lines; verify contact block compatibility for load current derating at elevated temperature.

500V DC rating covers battery-backup or DC motor drive control circuits that many 250V pushbuttons cannot handle.

When to choose this part

Choose this momentary SPST-NO for start/stop or acknowledge buttons; A6X30141188 (maintained black, 30.5mm cutout) suits hold-in or selector logic instead.

Yellow variant A6X30140588 shares the 22.3mm cutout but uses maintained switching—select based on whether the circuit requires latching after press.

Both the blue and yellow 22mm variants require separate contact blocks for load switching; budget for 3SU1 contact block SKUs in the BOM.

Limitations & things to verify

No illumination source integrated—pair with 3SU1 LED module (e.g., A6X30143984) if pilot light function is needed.

Requires separate contact block(s) for load switching; sourcing and BOM integration is the buyer's responsibility.

Frequently asked questions

What is the difference between this momentary pushbutton and the maintained black pushbutton A6X30141188?

The A6X30142988 is momentary (off-mom): the contacts return to open when the button is released. The A6X30141188 is maintained: contacts stay closed after the button is pressed. Additionally, A6X30142988 fits a 22.30mm panel cutout while A6X30141188 requires a 30.5mm cutout.

Can this switch handle 500V DC loads?

Yes. The A6X30142988 is rated 500V DC and 500V AC, both at 10A. Verify contact block derating if switching inductive DC loads at elevated ambient temperature.

What panel cutout size does the A6X30142988 require?

The panel cutout is circular, 22.30mm diameter. This is the standard 22mm pushbutton footprint used in many industrial control enclosures.

Does this pushbutton include contact blocks?

No. The A6X30142988 is the actuator head only. Contact blocks (3SU1 series) must be ordered separately to complete the switching circuit.

What sealing level does the A6X30142988 provide?

IP66/IP67/IP69K rating. It is dust-tight, water-resistant, and waterproof against high-pressure washdown and temporary submersion—suitable for food processing, pharmaceutical, and outdoor panels.
