22 mm Green Push Button Operator

The SIEMENS 3SU1050-0AB40-0AA0 is a momentary push button operator designed for industrial control panels. Its 22 mm mounting diameter fits standard cut-outs in enclosures and machines. The green flush head provides clear visual identification for start or go functions. It suits panel builders and maintenance engineers specifying IEC-compliant control devices.

Metal Bezel With IP69K And NEMA 4X

The single specification that decides fit is the combination of a metal bezel, IP69K ingress protection and NEMA ratings 1, 2, 3, 3R, 4, 4X and 12. This sealing level withstands high-pressure, high-temperature wash-downs common in food, beverage and pharmaceutical plants. Lower-rated operators would fail in those environments.

CE CSA UL Certifications For Global Compliance

The operator carries CE, CSA and UL markings, confirming conformity to European, Canadian and US safety standards. No legend is printed on the head, so users apply custom labels matching their application. The certifications reduce documentation effort when the finished panel is shipped to multiple regulatory zones.

Questions about this item

What does the 22 mm cut-out mean when I install this button in a panel?

The 22 mm cut-out is the standard mounting hole size; the operator fits through the hole and the metal bezel secures it from the front.

Which NEMA ratings apply and what environments do they cover?

Ratings 1, 2, 3, 3R, 4, 4X and 12 mean the operator is suitable for indoor, outdoor, wash-down and corrosive locations.

How deep is the operator behind the panel once mounted?

The flush-button design keeps the front profile low; exact behind-panel depth depends on the contact block you choose.
