New Enclosures Regolus Ex blind enclosures made of aluminum alloy for use in environments at risk of explosion
under Directive ATEX94 / 9 / EC.
These enclosures are to be considered components. The components require subsequent certification / declaration
by the user.
The cover is secured to the box with stainless steel screws, the tightness is ensured by a silicone seal that allows
to maintain a degree of protection IP65.
The containers are provided in different versions depending on the size of the metal box (and therefore of the
maximum power that can be dissipated) and the colorations provided.
The ATEX mark (ATmospheres EXplosives) refers to two European directives concerning the risk of deflagration
in potentially explosive atmospheres.
AREA CLASSIFICATION “Gases and Vapors”
Zone 1: place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the
form of gas, vapor or mist is likely to occur in normal operation occasionally.
Zone 2: place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the
form of gas, vapor or mist is not likely to occur in normal operation but, if it does occur, will persist for a short
period only.
AREA CLASSIFICATION “Dust”
Zone 21: area in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to
occur occasionally in normal operation.
Zone 22: area in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to
occur in normal operation but, if it does occur, will persist for a short period only.
