Aluminium distribution boxes have proven to be an excellent solution for encapsulating and shielding components and modules in electronic and pneumatic engineering. Bottom and lid of the distribution boxes come with earthing screws for the connecting of the protective conductor. Mounting threads in the bottom section, fixing holes outside of the sealed space.

The same high quality explosion-proofed enclosures are used in hazardous areas by inflammable dust (Zone 21 and 22). By means of the heating calculation according to the supplement to the test certificate and a separate IP-protection test, the basic requirements of the “protection through enclosure“ type of protection are met.
