Certified Junction Box
Overview
The explosion-proof control box has obtained Class II explosion-proof certification and T-class temperature certification, making it suitable for hazardous areas where the atmosphere contains mixtures of explosive gases (Classes IIA, IIB, IIC; Temperature Classes T1–T6) and explosive dusts. It is widely utilized in explosive environments such as oil refining, petroleum extraction, natural gas production, chemical manufacturing, grain processing and storage facilities, and gas stations.
