The T4 classification specifies that electrical devices must operate with a maximum surface temperature of no more than 135°C.

The explosion-proof classification T6 surpasses that of T1; Explosion-proof devices classified under T1 are required to maintain a surface temperature not...

IIC designations are used in environments containing hazardous gases like hydrogen, acetylene, and carbon disulfide, while IIIC designations apply to...

It is evident that CT4 holds a higher explosion-proof rating. Notably, explosion-proof motors feature the IICT4 designation but lack the IICT2 marking.

The distinction stems from varying temperature classifications, with surface temperatures arranged in descending order from T1 to T6.

The correct classification is IICT1, which permits the use with IIC class explosive gases. The T1 classification specifies that the equipment's maximum...
