ATEX safety bumpers

The electrical circuits of such apparatuses are incapable of causing an explosion in the surrounding explosive atmospheres and therefore they do not fall into the application field of the European Directive 2014/34/EU (ATEX) (EN 60079-11:2012, Art. 5.7).

The temperature class T6 [IEC-EN 60079-11 – Simple Apparatus Form] has been assigned to the internal contacts of these bumpers. They can be incorporated into intrinsically safe systems with “ia” protection level, for substances belonging to groups IIA, IIB and IIC (gas or flammable vapours) and/or of groups IIIA, IIB and IIC (combustible dusts).
