The 3SU11000AB103CA0 is a front-panel momentary pushbutton from Siemens' SIRIUS ACT 3SU1 series. The SPST-NC (normally closed) contacts switch on press and return on release. IP69K sealing supports high-pressure washdown, making it suitable for food, pharmaceutical, and outdoor enclosures. Box packaging is standard for this configuration.

3SU11000AB103BA0 — Shares SPST-NO (normally open) contacts versus the seed's NC configuration. Same black actuator, 10A rating, and IP66/IP67/IP69K. Use where load must energize on press rather than de-energize.
3SU11000AB103FA0 — Provides DPST-NO/NC dual-throw contacts in one unit. Two circuits activate simultaneously: one NC, one NO. Same mounting and sealing; useful when a single operator must drive two separate loads.
3SU11000AB101CA0 — Matches the seed contact type (SPST-NC) and black color. Part of the same 3SU1100 base series; variant likely reflects a different manufacturing revision or labeling.
Engineering Verification Checklist
- Confirm SPST-NC contact behavior matches circuit (should break load on press)
- Verify 10A rating adequate for driven load with appropriate derating for inductive loads
- Check panel cutout dimensions match SIRIUS ACT 3SU1 mounting requirements
- Validate IP69K gasket and retainer hardware included or ordered separately
- Confirm operating temperature range acceptable for target environment
- Verify contact material suitable for DC loads if not strictly AC application
- Review need for auxiliary contact block for ladder logic feedback or monitoring
- Confirm illumination option not required (no lamp spec present in seed)
- Check SIRIUS ACT accessories compatibility (lenses, holders, legends)
