B-05 SS316L Explosion-proof Power & Lighting Control Box IP66 Ex db IIB T6 Gb

1. Certified for Zone 1 and Zone 2 explosive gas atmospheres (Group IIB, Temperature Class T4) and explosive dust atmospheres, suitable for use in oil & gas, petrochemical plants, offshore platforms, and power stations for power and lighting control in hazardous locations.
2. Rated voltage up to AC 440 V (insulation voltage 660 V, 50 Hz), rated current up to 63 A, meeting industrial power distribution and lighting control requirements with complete circuit protection for stable operation.
3. Suitable for ambient temperatures from –30 °C to +40 °C (24-hour average not exceeding +35 °C), at altitudes not exceeding 2000 m, with IP66-rated protection ensuring reliable long-term performance in outdoor and severe industrial conditions.

1. Flameproof Ex db IIB T4 Gb structure effectively contains any internal explosion and prevents flame propagation to the surrounding hazardous atmosphere; flameproof joints are non-repairable by design, and all cable glands or stopping plugs must hold a valid CCC certificate — the unit is prohibited from installation in static-prone areas to avoid electrostatic ignition hazards.
2. IP66-rated enclosure with temperature- and corrosion-resistant rubber gaskets ensures excellent dustproof and waterproof performance; available in high-strength carbon steel, SS304, or SS316L (optional) for strong resistance to rust, chemicals, and mechanical impact in harsh industrial environments.
3. Supports both wall-mounted and floor-mounted installation with customizable cabinet dimensions, internal circuit layout, switch combinations, and component configurations to meet specific project requirements; the optimized inner layout with reasonable wiring space facilitates routine inspection, component replacement, and future maintenance.
