1. Aluminum alloy die-cast housing undergoes high-speed shot blasting followed by high-pressure electrostatic powder coating for corrosion resistance and aging resistance;
2. Stainless steel exposed fasteners provide superior corrosion resistance;
3. This series features a composite structure: the main chamber employs explosion-proof construction (IIB type with flat-face explosion-proof, IIC type with flanged explosion-proof), while the wiring chamber uses increased safety construction;
4. Equipped with high-breaking capacity miniature circuit breakers or molded case circuit breakers. The cover features a PC operating handle with a patented new mechanism, offering a simple, rational design, high versatility, and convenient operation;
5. Sealing strips utilize advanced one-step wire-pour foaming molding technology for superior protection;
6. Compatible with both steel pipe and cable wiring.
1. Suitable for Zone 1 and Zone 2 locations in explosive gas environments;
2. Suitable for Class IIA, IIB, and IIC explosive gas environments;
3. Suitable for Zone 21 and Zone 22 locations in explosive dust environments;
4. Suitable for Class IIIA, IIIB, and IIC explosive dust environments;
5. Suitable for temperature classes T1 to T6;
6. Suitable for hazardous environments in petroleum extraction, refining, chemical processing, military applications, offshore oil platforms, tankers, defense industries, metal processing, and similar settings.
