Research Notes
1. Overview
The catalog MLFB 3SU1132-0AB20-1BA1 does not exist — zero web hits, absent from Siemens' datasheet index, SiePortal, Industry Mall, and every distributor checked. It's a corrupted variant of the genuine, actively-sold 3SU1132-0AB20-1BA0: a SIRIUS ACT 3SU1 complete-device pushbutton — 22mm round, plastic with metal front ring, red, illuminated, flush actuator, momentary, 1 NO contact, LED module 24V AC/DC, screw terminal. SIRIUS ACT is modular: this "complete unit" bundles head + holder + LED module + contact block, but the head also sells bare (3SU1002 series) for pairing with separate plug-in contact modules (3SU1400 series, up to 6 contacts).
2. User Sentiment
No forum/community discussion — a commodity industrial part sourced via distributors. Framing across RS Components and regional resellers is neutral/routine.
3. Real-World Applications
Standard 22mm panel pushbutton for machine HMI stations and motor-control cabinets. Red illuminated buttons here typically serve stop/reset/fault-acknowledge roles; the stackable module design lets one holder carry the head plus extra contacts for multi-function layouts.
4. Technical Specifications
- Corrected MLFB: 3SU1132-0AB20-1BA0 — no valid SIRIUS ACT suffix ends in "1"; Siemens' System Manual function-letter table shows every real suffix ending in "0" (xBA0, xCA0, xDA0, xEA0, xFA0, xGA0, xHA0, xLA0–xRA0)
- Contact: 1 NO (true value for -1BA0, function "B"; catalog's stored "1NC" mismatches this MLFB)
- Color: Red (0AB20, confirmed; contrast: 0AB40=green, 0AB60=white in-family)
- Voltage: 24V AC/DC, correct (3SU1132=24V; 3SU1136=230V, per sibling 3SU1136-0AB20-1FA0)
- Illumination: Yes; Actuator: Flush, momentary
- Front ring: Metal; Terminal: Screw
5. Ordering & Compatibility
A genuine 1NC twin exists in the same color/family — 3SU1132-0AB20-1CA0 (function "C"=1NC), confirmed red/momentary/NC by RS Components Spain. If the catalog's "1NC" field is the trustworthy anchor rather than the "-1BA1" string, -1CA0 is the correct MLFB (two edits from the stored PN vs. one for -1BA0, making -1BA0 the more parsimonious fix, though both are genuine parts). Compatible with 3SU1400-series contact modules and 3SU1002 bare holders.
6. Known Issues
Primary: stored PN is invalid — likely a single-digit typo (trailing 0→1) of 3SU1132-0AB20-1BA0. Secondary: contact-field conflict — -1BA0 is universally documented as 1NO, not the catalog's stated 1NC; if 1NC was truly intended, the correct MLFB is 3SU1132-0AB20-1CA0 instead. Recommend correcting the record to one of these two real SKUs, with MLFB and contact field brought into agreement.

Referência rápida de instalação
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.

Solução 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.
