1. The enclosure is formed by die-casting aluminum alloy or welding carbon steel or stainless steel. Aluminum alloy/carbon steel surfaces feature high-pressure electrostatic powder coating, while stainless steel surfaces have a brushed finish, ensuring corrosion resistance and aging resistance. Exposed stainless steel fasteners provide superior anti-corrosion performance.
2. This series adopts a composite structure overall, with the main chamber employing a flanged explosion-proof design and the wiring chamber utilizing an increased safety design.
3. The enclosure employs a modular assembly design, allowing flexible combination of various circuits.
4. Switch handles are standardly made of PC material but can be customized in metal upon request. Main and branch switch operation panels can be color-coded for differentiation. Handles can be equipped with padlocks to prevent accidental operation.
5. Can be internally fitted with electrical components such as circuit breakers, AC contactors, thermal relays, surge protectors, universal changeover switches, fuses, instrument transformers, meters, and pushbuttons per user requirements.
6. Each circuit is equipped with corresponding signal indicator lights.
7. Sealing strips utilize advanced one-step molded foam casting technology, providing high protection performance.
8. Vertical installation includes corresponding mounting brackets. For outdoor use, rain covers or protective enclosures can be added, with materials customizable per user requirements.
9. Suitable for both steel conduit 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.
