Class IIB is designated for environments with hazardous gases like ethylene, where T6 specifies that explosion-proof electrical devices must maintain a surface temperature below 85°C.
IICT6
Class IIC applies to extremely hazardous areas with gases such as hydrogen, acetylene, and carbon disulfide. T6 classification ensures that these explosion-proof devices also maintain a maximum surface temperature of no more than 85°C.
Although both classes are rated T6, equipment under Class IIC offers enhanced safety. Consequently, IICT6 holds a higher explosion-proof rating than IIBT6.
