Industrial Control Operator

The SIEMENS 3SU1100-0AB40-1FA0 is a 22 mm flush push button operator designed for industrial control panels. It provides a momentary action with a green plastic head and a 1NO/1NC contact block rated for 10A at 600V AC and 1A at 600V DC. The unit carries NEMA A600/R300 designation and suits applications requiring a single, non-illuminated manual input device.

Environmental Protection

The operator achieves NEMA ratings 1, 2, 3, 3R, 4, 4X, 12 and IP ratings IP66, IP67, IP69, IP69K for robust sealing against dust, water jets and high-pressure wash-down. These ratings mean the device withstands harsh industrial environments without additional enclosures. The plastic bezel and head resist corrosion while maintaining the specified ingress protection during normal operation.

Panel Integration

Screw terminal connections simplify wiring during installation or maintenance. The 22 mm mounting diameter fits standard panel cut-outs, while the flush button profile reduces accidental actuation. Compliance with REACH and WEEE (2012/19/EU) confirms material and end-of-life regulatory adherence. The green colour coding follows common industrial conventions for start or safe-condition functions.

Questions about this item

How do I install the 22 mm flush push button operator and what is the common wiring mistake?

Mount the operator in a standard 22 mm panel cut-out and secure the bezel; the step often missed is tightening both the 1NO and 1NC screw terminals to the 10 A / 600 V AC rating so the safety circuit remains complete.

What maintenance or replacement will the green flush push button need over time?

The plastic head and bezel are rated IP66, IP67, IP69 and IP69K; inspect the seal integrity periodically and replace the operator if the green colour fades or the momentary action becomes sticky.

What is the first limit that appears under sustained use of this 1NO/1NC contact block?

The contact rating of 10 A at 600 V AC (A600) and 1 A at 600 V DC (R300) is the electrical limit; exceeding either current value will cause premature contact wear.
