Std ATEX ExD IIG = NEMA 7 ?
Std ATEX ExD IIG = NEMA 7 ?
(OP)
Hi everybody!!!!
I have a question, if I want to use a NEMA 7 enclosure, you know that NEMA 7 are made of aluminum exent of copper and enclosures with standard ATEX Eexd IIG have enclosures explosion proof of aluminum exent of copper...can I use an enclosure of std atex AS A NEMA 7??? DOES STD ATEX EEXD IIG HAVE CLASIFICATION 1 DIV 2 GROUP ABC AND D???
Regards.
Roland

That ATEX certification looks incomplete anyway, there should be a gas group and temperature class listed too. The information presented says it's a flameproof enclosure for surface (i.e. non-mining) duty with gaseous flammables but exactly which gases and which maximum surface temperature isn't stated.

The certification also falls short in US marking requirements and pretty much for the same reasons (unspecified gas and temperature classifications) In addition, the NEC requires an "AEx" rather than "EEx" mark to indicate it was certified to a US "Zone" standard.
Oddly enough, with a proper temperature classification mark, it may still be fine in Class I, Division 2.
