The A6X30144193 is a non-illuminated, front-panel-mount pushbutton from the Siemens 3SU1 series. It ships as a complete assembled unit with integrated contact block (DPST-NO/NC). Panel installers must confirm front-of-panel thickness and provide a 22.3 mm round cutout.
Design and Application Trade-Offs
- DPST-NO/NC dual-function contacts — Simultaneous open and closed poles enable simple logic without external wiring, but the fixed configuration cannot accommodate future circuit changes without hardware replacement.
- IP66/IP67/IP69K sealing — The three-tier ingress protection suits high-pressure washdown and temporary submersion, yet adds cost and bulk compared to IP40 alternatives.
- 10 A AC/DC rating — Rated for moderate loads across both AC and DC circuits; however, DC switching at comparable current imposes higher contact wear due to arcing characteristics.
- 10 million cycle endurance — Mechanical and electrical life match at 10M cycles, avoiding premature wear divergence; however, actual cycling life depends on load type, actuation force, and environmental conditions not specified here.
Engineering Verification Checklist
- Verify DPST-NO/NC contact topology matches circuit schematic before installation.
- Confirm panel thickness is within 3SU1 series tolerance for front-mount retention.
- Measure panel cutout diameter: 22.3 mm nominal; verify clearance for bezel.
- Check IP69K sealing gasket orientation and integrity after mounting.
- Validate current and voltage do not exceed 10 A AC/DC under actual load conditions.
- Test circuit operation under expected ambient temperature range (25°C–70°C).
- Confirm switching function at minimum and maximum rated current for both poles.
- Verify contact block retention clips are fully engaged after mounting.
- Inspect actuator travel and return spring behavior after mechanical cycling.
