Electric motors in an explosion-proof enclosure are intended for use in places where an explosive environment is likely to occur, created by mixtures of air and gases, vapors, mists (environments saturated with propane, industrial methane, ammonia, gasoline, naphtha, oil, acetone, alcohol, diethyl ether vapors), mixture of air and dust in zones 21 and 22. As well as motors for use in underground workings of mines, mines, hazardous with respect to firedamp and / or combustible dust, as well as in those parts of their above-ground structures in which there is a danger of the presence of firedamp and /or combustible dust (mixture category - I).
