Explosion-proof products are divided into explosion-proof electrical products and non-electrical products. Products with explosion-proof 3C certification are limited to explosion-proof electrical products and do not include non-electrical products or combined products. Currently, explosion-proof electrical products are classified into 17 categories, namely: 1. Explosion-proof motors: with a center height of ≤160 mm, or a rated power of ≤15 kW; explosion-proof motors: 160 mm
