Please look for it under \"electrical explosion protection\". Check the website below to find the answer. http://www.gongkong.com/forum/ForumTopic.aspx?Id=2008122616541300001

This is the protection type; it’s very important, so study it carefully*

Ex is a mark indicating explosion protection; how could you mistake it for a type of protection? Too amateurish. You need to study hard*, ya.

EX-i is intrinsically safe explosion protection; within this category, there are two subtypes: ia and ib. Type ia can be used in Zones 0, 1, and 2, while type ib can only be used in Zones 1 and 2. EX-n is a non-spark-type explosion protection system that also has several subcategories, but it is only suitable for Zone 2. EX-d is a flameproof explosion protection system that can be used in Zones 1 and 2. EX-e is a enhanced safety explosion protection system that can be used in Zones 1 and 2
