Siemens 22 mm Green Push Button Operator
The Siemens 3SU1051-0AB40-0AA0 is a 22 mm illuminated push button operator designed for industrial control panels. It features a momentary flush button with a green polyamide head and a nickel-plated brass and zinc die-cast bezel. The unit carries NEMA 1, 2, 3, 3R, 4, 4X, 12 and IP69K ratings for demanding environments. It is supplied new without a lamp module or legend.
Suits panels needing a momentary green actuator
This operator suits panels requiring a momentary green actuator with high ingress protection. It is not for applications needing a maintained switch action or an integrated light source. Buyers who want a complete illuminated unit must source a separate lamp module. Installers requiring a legend plate must order one separately.
22 mm mounting diameter decides fit
The single specification that decides fit is the 22 mm mounting diameter. The panel cut-out must match this dimension exactly for correct installation. All NEMA and IP ratings apply only when mounted in a compatible enclosure. Verify the cut-out size before ordering.

Questions about this item
Does this 22 mm push button operator require a separate lamp module to illuminate the green head?
Yes, the lamp module is not included; you must supply a compatible module to provide illumination for the green polyamide head.
Can this operator be mounted in the same 22 mm cut-outs used by older NEMA 1, 12, 2, 3, 3R, 4, 4X rated devices?
Yes, it fits standard 22 mm cut-outs and carries NEMA 1, 12, 2, 3, 3R, 4, 4X ratings for compatibility with existing enclosures.
How can I verify the IP69K seal is effective after installing the operator in a panel?
After installation, inspect the bezel gasket for uniform compression and run a high-pressure wash test; no water ingress confirms the IP69K rating.
