CT4 and CT6 indicate operational surface temperatures, not the withstand temperatures, for explosion-proof products. Products classified under the T6 category provide enhanced safety due to their lower operational surface temperatures compared to the T4 category.
| Grup suhu pakakas listrik | suhu permukaan maksimum allowable pakakas listrik (℃) | Suhu ignition gas / uap (℃) | tingkat suhu alat lumaku |
|---|---|---|---|
| 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 |
The CT4 explosion-proof motor carries an Exd IIC T4 rating and is generally used in environments where the ambient temperature is approximately 135℃.
