Polyester enclosures have been of great advantage in many industrial plants. They offer safe protection even when they are exposed to extreme environmental conditions, aggressive chemical media or high mechanical stress. The narrow sides within the enclosure hold threaded bushings for the fixing of terminal rails or mounting panels. The is mounted by means of insulated screws outside of the lid sealing gasket.These black high-quality explosion-proofed enclosures are used in hazardous areas by inflammable gas (Zone 1 and 2) and dust (Zone 21 and 22). The fundamental prerequisites of the “protection through enclosure“ protection class are fulfilled with the heating up calculation as per the accompanying sheet and a separate IP protection test.
