3SU1130-0AB20-1CA0
सक्रियSIRIUS ACT Red Flush Push Button (1NC)
Red flush momentary push button, Siemens SIRIUS ACT series. 22mm cutout, IP66/IP67/IP69K, metal housing, with 1NC contact.
सामान्य अनुप्रयोग
Red stop button from the SIRIUS ACT range. Paired with the green 3SU1130-0AB40-1BA0 on Siemens-controlled machinery. The 1NC contact is standard for stop functions. Found on Siemens-automated lines in automotive manufacturing, pharmaceutical filling lines, and semiconductor fab equipment. The metal front ring matches the premium aesthetic expected in clean-room and pharmaceutical environments.
Research Notes
1. Overview
The Siemens 3SU1130-0AB20-1CA0 is a non-illuminated, complete-device pushbutton from the SIRIUS ACT 3SU1 series — Siemens' flagship modular industrial command-and-signaling portfolio. It features a 22 mm round actuator in red with a flat (flush) button profile, a plastic body with a metal front ring, a momentary (non-latching) action, and a single normally-closed (1NC) contact block with screw terminals. As a "complete device" (3SU113x), the actuator head and contact module are supplied as one pre-assembled, ready-to-mount unit, simplifying installation vs. building from separate 3SU10x components. It installs into a standard 22 mm panel cutout.
2. User Sentiment
No field reviews or end-user forum posts were recoverable from public web sources for this specific part number. The broader SIRIUS ACT family enjoys a strong reputation in industrial automation: users consistently cite the snap-on modular design that allows single-handed assembly/replacement, the rugged high-grade plastic and genuine-metal construction, and IP69K-grade ingress protection as differentiators vs. competing platforms. The series is widely stocked by major distributors (Farnell, Mouser, Digi-Key, RS Components) and listed on the Siemens Industry Mall, indicating good commercial availability and distribution depth.
3. Real-World Applications
SIRIUS ACT 3SU1 pushbuttons are found across virtually all industrial sectors:
- Machine tool control panels (start/stop, feed hold, cycle start)
- Conveyor and material-handling systems
- Packaging machinery operator stations
- Process plant field panels (pumps, valves, agitators)
- Crane and hoist pendant controls
- ATEX-rated enclosures for hazardous areas (intrinsically safe circuits per IEC 60079-11)
- Any 22 mm standard-format industrial enclosure requiring a normally-closed interlock or stop function
The red color and 1NC configuration make this actuator particularly suitable for machine-stop or interlock functions where the normally-closed path must open on actuation.

5. Ordering & Compatibility
The 3SU1130-0AB20-1CA0 is orderable through the Siemens Industry Mall (redirects to SiePortal) and authorized distributors worldwide. Part number key: 3SU1130 = complete device, plastic, flat button; -0AB20 = red color, flat actuator; -1CA0 = 1NC screw-terminal contact module. Compatible accessories within the 3SU1 ecosystem include:
- 3SU14xx LED modules (to upgrade to an illuminated variant, e.g. 3SU1152-0AB20-1CA0)
- 3SU15xx holders and 3SU18xx enclosures
- AS-Interface and IO-Link electronics modules (3SU14xx) The illuminated equivalent is 3SU1152-0AB20-1CA0 (integrated LED, 24 V AC/DC). A 1NO variant uses suffix -1BA0 instead of -1CA0. The black-actuator version replaces -0AB20 with -0AB10.
6. Known Issues
No significant issues reported in publicly available sources. The SIRIUS ACT series is well-established and broadly deployed; no product advisories, recalls, or widespread field complaints were found for the 3SU1130-0AB20-1CA0. The main installation note in Siemens documentation is to ensure the 22 mm panel cutout meets the tolerance spec for proper IP sealing.

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.

उपयोगकर्ता क्या कह रहे हैं
“Yes, they cost 30-40% more than Eaton or Schneider equivalents. But the IP69K rating is standard, not an upcharge. The metal housing is noticeably more solid. For food & bev or pharma where washdown is daily, the math works out.”
