22 mm Green Metal Bezel Push Button

This SIEMENS 3SU1150-0BB40-1FA0 is a momentary extended push button operator with a 22 mm mounting diameter. It features a green plastic head, metal bezel, and a 1NO/1NC contact block rated at 10A for 600V AC and 1A for 600V DC. The unit carries NEMA A600/R300 designation and meets NEMA 1, 12, 2, 3, 3R, 4, 4X ratings alongside IP66, IP67, IP69, and IP69K protection. It is suited for industrial control panels requiring robust manual actuation.

Verify Panel Cutout and Wiring

Before ordering, confirm your panel provides a standard 22 mm cutout for this operator. Ensure your control circuit operates within the 600V AC or DC rating and that the 10A AC or 1A DC contact capacity matches your load requirements. Check that screw terminal connections are compatible with your wire gauge and termination method. The momentary action returns automatically, so verify this behaviour fits your control logic.

Metal Bezel and High IP Ratings

The metal bezel provides mechanical durability for demanding environments while the plastic head resists corrosion. Combined IP66, IP67, IP69, and IP69K ratings mean the operator withstands powerful water jets, temporary immersion, and high-pressure, high-temperature washdowns common in food or pharmaceutical processing. Screw terminals give a secure, maintainable connection that resists vibration loosening over time.
