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.
विद्युत उपकरणों का तापमान समूह | विद्युत उपकरण का अधिकतम स्वीकार्य सतह तापमान (℃) | गैस/वाष्प ज्वलन तापमान (℃) | लागू डिवाइस तापमान स्तर |
---|---|---|---|
टी1 | 450 | >450 | टी1~टी6 |
टी2 | 300 | >300 | टी2~टी6 |
टी3 | 200 | >200 | टी3~टी6 |
टी -4 | 135 | >135 | टी4~टी6 |
टी5 | 100 | >100 | टी5~टी6 |
टी6 | 85 | >85 | टी6 |
The CT4 explosion-proof motor carries an Exd IIC T4 rating and is generally used in environments where the ambient temperature is approximately 135℃.
