The explosion-proof classification T6 surpasses that of T1;
| Temperature Classification for Electrical Equipment | Maximum Permissible Surface Temperature of Electrical Equipment (°C) | Gas/Vapor Ignition Temperature (°C) | Applicable Equipment Temperature Class |
|---|---|---|---|
| T1 | 450 | ＞450 | T1~T6 |
| T2 | 300 | ＞300 | T2~T6 |
| T3 | 200 | ＞200 | T3~T6 |
| T4 | 135 | ＞135 | T4~T6 |
| T5 | 100 | ＞100 | T5~T6 |
| T6 | 85 | ＞85 | T6 |
Explosion-proof devices classified under T1 are required to maintain a surface temperature not exceeding 450°C, while those classified under T6 must not exceed a surface temperature of 85°C;
Undoubtedly, T6 offers enhanced safety.
