The newly developed AAB-X22/X2 expands the application range of our junction boxes for potentially explosive atmospheres. Possible fields of application are now areas endangered by dust (ATEX zone 22) as well as by gas (ATEX zone 2). Thanks to the polyester enclosure, the branching and connection box AAB-X22/X2 is robust, shockproof and resistant even under the special environmental conditions such as in the chemical industry. The original branch box AAB-X22 is replaced by the improved AAB-X22/2.
