Research Notes
1. Overview
The catalog stored this SKU as 3SU1132-0AB50-1BA1 — invalid (no genuine SIRIUS ACT suffix ends in "1"). The corrected part, 3SU1132-0AB50-1BA0, is confirmed genuine directly from Classic Automation's product page: "ILLUMINATED PUSHBUTTON, MOM, BLU, FLUSH," Color: Blue, Button Style: Flush, Operation: Momentary. RS Components independently lists it as "SIRIUS ACT Illuminated Blue Flat Push Button Complete Unit, SPNO, 22mm Momentary Screw." Same SIRIUS ACT 3SU1 complete-device family as #335 (red): 22mm round, plastic + metal front ring, flush, momentary, integral 24V AC/DC LED, 1 NO, screw terminal.
2. User Sentiment
No forum/community discussion — routine commodity industrial part. Distributor listings (RS Components, Classic Automation, Heitek, eibabo) are neutral spec-sheet entries.
3. Real-World Applications
22mm panel pushbutton for machine HMI/control cabinets. Per IEC 60204-1 convention, BLUE denotes a "mandatory action" function — commonly a reset-to-a-specific-state command where no other reserved color applies. The illuminated cap also serves as a status/prompt indicator.
4. Technical Specifications
- Corrected MLFB: 3SU1132-0AB50-1BA0 (stored "-1BA1" invalid; trailing digit corrected 1→0)
- Color: Blue — 0AB50 confirmed directly via Classic Automation ("BLU"/"Blue") and RS Components ("Blue"); consistent with family anchors 0AB20=Red, 0AB30=Yellow, 0AB40=Green, 0AB60=White
- Contact: 1 NO (function "B"); Voltage: 24V AC/DC (3SU1132 class)
- Illumination: Yes, integral LED; Actuator: Flush, momentary
- Front ring: Metal; Terminal: Screw; Protection: IP66/IP67 (SIRIUS ACT family rating)
- Stored catalog color "Blue" is CORRECT — matches 0AB50 authoritatively.
5. Ordering & Compatibility
Genuine part confirmed by Classic Automation, RS Components, Siemens' teddatasheet index ("Data sheet 3SU1102-0AB50-1BA0"), and a live Siemens Industry Mall WW page for the exact MLFB. Sibling variants (3SU1152-0AB50-1BA0 via eibabo/Heitek, 3SU1102-0AB50-1BA0 via Kempston) confirm the same blue/flat/momentary/1NO pattern family-wide. Compatible with 3SU1400-series contact modules and 3SU1002 bare holders.
6. Known Issues
Same trailing-digit corruption as siblings: stored "-1BA1" should read "-1BA0". No contact-field or color-field conflict identified — stored color "Blue" is correct and the single-digit fix fully resolves the MLFB.

Referencia rápida de instalación
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Solución de problemas
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
