GB3836.2-2000 Electrical Apparatus for Explosive Gas Atmospheres Flameproof Enclosure “d”
and standards IEC79-1, BS4683 and EN50018. The explosion protection marks are ＥｘｄⅠ， Ｅｘｄ ⅡＡＴ４ ａｎｄ Ｅ ｘｄⅡＢＴ４. They are safe to use in the locations where there are explosive mixtures of gas- and vapor-air.
“ＥｘdⅡBT4”--- safe for use in plants where the explosive mixtures of ⅡB Class, TI, T2, T3 or T4 are present.
“ＥｘdⅡCT4”--- safe for use in plants where the explosive mixtures of ⅡC Class, TI, T2, T3 or T4 are present.
“ＥｘdⅠ” --- safe for use in the non- mining surfaces of underground coal mines where the explosive mixtures of methane or coal-dust are present.
“ＥｘdⅡAT4”--- safe for use in plants where the explosive mixtures of ⅡA Class, TI, T2, T3 or T4 are present.
For this series motors, the output ratings and mounting dimensions conform to the specifications of IEC standards and the correlation between them basically agrees with EIN42673. The motors are easy to complete with export machinery and equipment and to supply as spare accessories in the import equipment.
