Research Notes
1. Overview
The Siemens 3SU1801-0AB00-2AB1 is a pre-assembled 1-button control station from the SIRIUS ACT 3SU1 22 mm line — a plastic enclosure with one green pushbutton labeled "I" (start/on) and a 1 NC contact, rated IP66/IP67/IP69. It's a ready-to-mount surface station for a single control function. (Data-quality note: this was cataloged as a "2-Button Start/Stop Station (Green + Red, 1 NO + 1 NC)" — per Siemens/RS it is a single green "I" button with 1 NC, not a two-button green/red start-stop station.)
2. User Sentiment
SIRIUS ACT enclosed stations are valued for quick installation (no panel cutout) and Siemens' current modular 3SU1 ecosystem (interchangeable operators, contacts, LED modules). A single-button green "I" station is a simple, compact control point. Considerations: confirm the exact button count, color/label, and contact from the full order number — as here, the configuration is easy to mis-state.
3. Real-World Applications
A single green "I" (start/on) control point mounted on a machine, wall, or frame without a panel cutout — e.g. a start or on command wired through the 1 NC (or a simple function button).
4. Technical Specifications
- Type: SIRIUS ACT 3SU1 1-button enclosed control station (surface-mount)
- Operator: one green pushbutton, "I" label (start/on), 22 mm
- Contacts: 1 NC
- Enclosure: plastic; IP66 / IP67 / IP69
- Approvals: UL, CSA, CE
- Line: Siemens SIRIUS ACT 3SU1 (current 22 mm range)
5. Ordering & Compatibility
Complete assembled 1-button station. For 2-button start/stop or other configurations, Siemens offers different 3SU180x order numbers — don't assume this single-green-button code is a start/stop pair. Uses standard SIRIUS ACT 3SU1 operators/contacts/holders for service. Empty 3SU1 enclosures exist separately for custom builds.
6. Known Issues / DQ
- DQ: it's a 1-button green "I" station with 1 NC — not a 2-button green/red start/stop with 1 NO + 1 NC. Corrected here (button count / color / contact).
- Practical care: verify the exact configuration from the full order number, and pick the correct 3SU180x code if a genuine 2-button start/stop station is needed.

इंस्टॉलेशन त्वरित संदर्भ
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.

समस्या निवारण
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.
