The GUB S series enclosures are designed for the installation in the industrial plants with potentially hazardous atmosphere classified as Zone 1 and Zone 2 for gases and Zone 21 and Zone 22 for combustible dusts. The Gub Series enclosures are presented wi t h 12 di fferent s i ze options, which allow to house various types of electronic and control components. Installation of the controlling equipment and measuring and regolation of fluids in the process are the typical applications. (For dimension, see data table for GUB S). The Enclosures can be equipped with a window, where a visual inspection is needed. Voltmeters, ammeters and analog & digital measure instruments are the typical example of the appl i cations. (For dimension, see data table for GUB W).
The Enclosures also can be equipped with an extension, where an extra height is needed. Television cameras are the
typical example of the applications.
