Code Significance
Explosion protection symbol
II Equipment group II, suitable for all potentially explosive
atmospheres other than underground parts of mines liable to
be endangered by firedamp.
3 Device category 3 means, equipment in this category is
intended for use in areas in which explosive atmospheres
caused by gases, vapors, fog, dust/air mixtures are not
expected to occur or, if they do occur, are likely to do so only
infrequently and for a short period only.
D Explosive material: Dust
Ex Standard for explosion protection has been applied.
tc Protection by enclosure for EPL Dc
IIIC Electric devices of group IIIC are intended for use in areas
where an explosive dust atmosphere ("C": conductive dust)
must be expected.
T155°C Maximum surface temperature within and outside of the
enclosure where explosive dust may occur.
Dc Equipment protection level (EPL) classification Dc for
advanced safety level for use in potentially flammable dust
atmospheres where there is no ignition risk during normal
operation and that have some additional safety measures
which ensure no ignition risk exists in the event of foreseeable
malfunctions.
