Siemens SIRIUS ACT 3SU1 Series Introduced circa 2013

Siemens 3SU1100-0AB40-1BA0 — SIRIUS ACT Green Flush Push Button Plastic (1NO)

Green flush momentary push button, Siemens SIRIUS ACT series. 22mm cutout, IP66/IP67, PLASTIC front ring — budget option. With 1NO contact.

Common Applications

Budget-friendly green push button from the SIRIUS ACT plastic range — same 22mm mounting and function as the metal 3SU1130-0AB40-1BA0 but with a plastic front ring at lower cost. Ideal for large panel builds with many buttons where the per-unit price matters, or for non-critical applications in climate-controlled environments. Found on Siemens-equipped packaging lines, light assembly stations, and building automation panels. The IP66/IP67 rating still provides solid protection against dust and water ingress. Pairs with Siemens 3SU1 contact blocks and the red 3SU1130-0AB20-1CA0 for start/stop stations.

Specifications

Actuator Shape The physical shape of the pressable surface.	Round
Actuator Type The button head style. Flush sits level with the bezel (prevents accidental presses). Extended protrudes for easy access.	Flush
Certifications Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.	UL, CSA, CE
Color Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).	Green
Contact Configuration Normally Open — circuit is off until you press. Standard for start/go/enable functions.	1NO
Cutout Diameter The hole size you drill in your panel to mount this button. 22mm is the most common industrial standard worldwide.	22mm
IP Rating IP67: Dust-tight and survives temporary water submersion (1m for 30 min). Handles oil splashes, steam cleaning, and rain.	IP66/IP67
Material The bezel/body material. Metal bezels are more durable in harsh environments. Plastic is lighter and cheaper.	Plastic
Mounting Type How the button attaches to the panel. Panel mount is standard — installs through a cutout from the front.	Panel

Installation Quick Reference

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.

Wiring Diagram

Troubleshooting

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.
