Selection Notes
Yellow is reserved on most panels for a caution, reset or manual-override function distinct from the green-run and red-stop pair; the unmarked XB4BA51 fits that role directly. Where the legend needs an explicit symbol instead of relying on colour alone, pick a marked variant in the same bezel and contact configuration from the XB4 range.
