II Equipment group II which is suitable for
all potentially explosive areas other than
firedamp-endangered excavations
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 unlikely to occur or, if they do occur,
are likely to do so only infrequently and
for a short period only.
G G = Gas
Ex The European standard for explosion
protection has been applied.

safety" for EPL Gc
IIB Explosion group
T 155 Maximum surface temperature of the
°C motor
(T3) Temperature class T3 <200°C
Gc Device protection level (EPL) classifica-
tion Gc for advanced safety level for use
in potentially gas explosive atmospheres
where there is no ignition risk during
normal operation or have any additional
safety measures which ensure in the
event of foreseeable faults/malfunctions
no ignition risk exists.
