22 mm Red Metal Bezel Push Button
This flush push button operator measures 22 mm and features a momentary action with a red plastic head and metal bezel. It carries a contact form of 1NO/1NC rated at 10A @ 600V AC and 1A @ 600V DC. The unit is designed for industrial control panels requiring a single operator.
Sustained Load Behaviour
Rated NEMA A600/R300, the contacts maintain performance under continuous industrial duty cycles. The IP66, IP67, IP69 and IP69K ratings ensure reliable operation when exposed to high-pressure washdowns and dust ingress over extended periods. NEMA 1, 12, 2, 3, 3R, 4 and 4X enclosures are supported for harsh environments.
Installation And Common Issues
Screw terminal connections simplify wiring during panel mounting in a standard 22 mm cutout. The metal bezel provides secure fastening but requires care to avoid cross-threading during installation. Verifying the correct contact block orientation prevents wiring errors that could lead to nuisance trips.

Questions about this item
How much heat or noise does the 3SU1150-0AB20-1FA0 generate when pressed continuously?
The push button is a passive mechanical operator with no internal power draw, so it produces no measurable heat or audible noise during continuous actuation.
What panel cut-out and wiring must already be in place for this 22 mm metal-bezel operator to install?
A standard 22 mm mounting hole and screw-terminal wiring rated for at least 10 A at 600 V AC or 1 A at 600 V DC are required before fitting the unit.
Will the 3SU1150-0AB20-1FA0 fit alongside legacy 22 mm operators that carry NEMA 1, 12, 2, 3, 3R, 4, 4X ratings?
Yes — it shares the same 22 mm mounting footprint and meets NEMA 1, 12, 2, 3, 3R, 4, 4X plus IP66, IP67, IP69 and IP69K, so it mounts directly beside older units.
