Explosion Protection Rating Explanation
View All Explosion-Proof MotorsEnclosure protection for combustible dust environments
Suitable for Class IIIC combustible dust environments (conductive and non-conductive), including grain, feed, wood, and metal dust, in Zone 21 and Zone 22. T130°C indicates the equipment's maximum surface temperature does not exceed 130°C. Db denotes a high protection level.
Filter products at this levelExplosion-proof marking explanation: "Ex" denotes explosion-proof; "d" indicates a flameproof enclosure; "tb" signifies an enclosure protection type (for dust explosion-proof). "I", "IIA", "IIB", and "IIC" represent applicable gas groups, while "IIIA", "IIIB", and "IIIC" indicate applicable dust categories. "T1–T6" or "T130°C" specifies the temperature class and maximum surface temperature. "Mb", "Gb", and "Db" denote equipment protection levels. When selecting equipment, verify based on the site's hazardous area classification (gas zones 1, 2 or dust zones 21, 22), medium group, and temperature class.
