1. Applications
Oil refineries, petrochemical plants, and natural gas processing facilities (gas Zone 1/2, dust Zone 20–22)
Coal mines, grain silos, and flour milling plants with combustible dust hazards
Offshore platforms, marine engineering, and coastal chemical installations
Military and defense sites requiring both gas and dust explosion protection in a single enclosure
Pharmaceutical and food processing areas where mixed gas-and-dust hazardous zones coexist
2. Features
Ten current ratings from 1A to 100A in one series, covering nearly all low-to-medium power control circuits
Dual explosion-proof certification (Ex dbⅡB T6 Gb + Ex tb ⅢC T80°C Db) — gas and dust protection in a single box
IP66 enclosure — fully dust-tight and protected against powerful water jets
Wide voltage compatibility: AC up to 690V and DC 24–48V, supporting diverse control systems
Electrostatic-safe design for dust environments; unused cable entries must be sealed with certified explosion-proof plugs, and all cable glands require valid explosion-proof certificate
