Meaning
II
Device group II = other hazardous areas (not the mining industry)
3 G
Device category 3 G = zone 2 atmosphere (gas)
Ex nAnC
nA = non-sparking operating material, nC = the contacts of sparking oper-
ating materials are protected in a suitable manner (ignition protection
types for electrical operating materials in areas at risk of gas explosions)
IIC
IIC = explosion group for gases (as per IEC, CENELEC and NEC 505; typ-
ical gas: hydrogen)
T4
T4 = temperature class for gases (maximum permissible housing surface
temperature 135 °C; as per IEC, CENELEC and NEC 505)
T6
T6 = temperature class for gases (maximum permissible housing surface
temperature 85 °C; as per IEC, CENELEC and NEC 505)
Gc
Device protection level: Gc corresponds to zone 2

Ex tc
tc = protection by means of a housing (ignition protection type for electrical
operating materials in areas at risk of dust explosions)
IIIC
IIIC = conductive dust (as per IEC, CENELEC and NEC 505)
T85°C
T85°C = highest permissible surface temperature for dust (as per IEC,
CENELEC and NEC 505)
T135°C
T135°C = highest permissible surface temperature 135 °C (as per IEC,
CENELEC and NEC 505)
