IECEx & ATEX Terminal Boxes
IP Enclosures’ IECEx and ATEX stainless steel terminal boxes are designed for electrical, electronic and pneumatic equipment used in hazardous and potentially explosive environments. Manufactured in Italy from high-quality stainless steel, the range provides a robust enclosure solution for demanding applications including oil and gas, mining, chemical and petrochemical processing, food processing and other industrial hazardous areas.
The IECEx range is certified as an Ex Component with protection methods Ex eb IIC Gb for gas atmospheres and Ex tb IIIC Db for combustible dust atmospheres. This makes the enclosures suitable for integration into equipment intended for hazardous areas, including applications associated with Zones 1 and 2 for gas and Zones 21 and 22 for dust, subject to the certification and design requirements of the completed equipment.
The terminal boxes feature a welded stainless steel body, screw-fastened lid, high-quality silicone sealing system, and provide excellent corrosion resistance in harsh industrial environments. With IP66 ingress protection, these hazardous-area terminal boxes provide reliable protection against dust and powerful water jets. The IECEx terminal boxes are certified to the applicable requirements of IEC 60079-0, IEC 60079-7 and IEC 60079-31.
The range is available in multiple sizes to provide a compact and durable enclosure platform for terminal connections, instrumentation and other electrical equipment used in hazardous locations.
