Selection Notes
The START legend makes the button's function unambiguous at the panel, which matters because the 30.5 mm mounting diameter is a larger-format cutout than the common 22 mm XB4/XB5 range, typically reserved for a primary start a sequence control that an operator needs to find without searching. The chromium-plated metal bezel and IP69K rating suit washdown or outdoor enclosures better than an equivalent plastic head.
