Shenhai a prova d'explosió
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 de temperatura dels equips elèctrics | Temperatura màxima de superfície permesa dels equips elèctrics (℃) | Temperatura d'ignició del gas/vapor (℃) | Nivells de temperatura del dispositiu aplicables |
|---|---|---|---|
| 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 |
| T 6 | 85 | >85 | T 6 |
The CT4 explosion-proof motor carries an Exd IIC T4 rating and is generally used in environments where the ambient temperature is approximately 135℃.
