Shenhai eksplosionssikker
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.
| Temperaturgruppe af elektrisk udstyr | Maksimal tilladt overfladetemperatur af elektrisk udstyr (℃) | Gas/damp antændelsestemperatur (℃) | Gældende enhedstemperaturniveauer |
|---|---|---|---|
| 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℃.
