Explosion protection

Explosion-proof devices must be used in plants where potentially explosive atmospheres are likely to occur. These devices are designed so that they will not act as ignition source. Their constructive measures prevent the occurrence of ignition sparks or hot surfaces.

 

Certification is performed in close collaboration with national and international certification bodies. The table below lists the various approvals of AUMA devices: ATEX (Europe), IEC (international level), and FM (USA).
