The Flameproof ATEX protection concept is providing a strong and closely fitting enclosure to protect its contents. The enclosure must be capable of containing an potential explosion. Any electronic sparking equipment may be placed in an flameproof enclosure, however there are some restrictions for fluids and batteries and minimum requirements for internal free space.

The first concept of protection is to have no arcs, sparks or hot  Explosión Protection Concepts. Type of. Protection. Symbol. Basic. Schematic.

ATEX Concepts – Type N (or N.I.) Protection (Non-sparking) Europe, NEC 500 and NEC505. A type of protection applied to an electrical apparatus such that, in normal operation, it is not capable of igniting a surrounding explosive atmosphere, and a fault capable of causing ignition is not likely to occur.

Protection concepts IECEx and ATEX. The table below lists the types of protection methods and basic concepts of protection according to ATEX and IECEx standards for electrical equipment that is to be operated or installed in hazardous areas. The matrix is constructed to enable the fast cross referencing of protection concepts for zones and related ATEX 94/9/EC (also ATEX 100a) and ATEX 99/92/EC (also ATEX 137). The ATEX Directive 94/9/EC sets out the Essential Safety Requirements for products and protective systems intended for use in potentially explosive atmospheres and the respective conformity assessment procedures.
