Allen-Bradley 800MR-QB24GA Industrial Relay Module

Allen-Bradley 800MR-QB24GA is a 22.5 mm round pushbutton operator from the 800MR family, featuring an extended head (QB) and a green lens (GA). Designed for industrial control panels, this model is intended to be used with a separate 800MR contact block to form a complete switch for control circuits; it does not include a power module, illumination, or a built-in contact block (Power Module Type None, Lamp Type None, Contact Type None). It is rated for 24 V AC/DC operation and is built for panel mounting with other 800MR accessories to customize function and appearance. The QB variant denotes an extended head for improved actuation reach and visibility, while the GA designation confirms the green lens color, enabling color-coded signaling in automation environments. To implement the final switching action, pair this operator with a compatible 800MR contact block and wire it according to the selected normally open or normally closed configuration supported by the chosen block. This 800MR-QB24GA is commonly used for start/stop, reset, or mode-selection functions within machine control, where a standard 22.5 mm operator with a green indicator is appropriate for clear, durable control in harsh industrial settings.
