Selection Considerations

• Material: Aluminum for lightweight corrosion resistance, stainless steel for extreme durability.
• Protection Type: Ex d (flameproof) for high-risk zones, Ex tb (dust protection) for dust-prone areas.
• IP Rating: Typically IP66 or higher for water and dust ingress protection.
• Customization: Modular designs allow integration of terminals, control devices, and monitoring systems.
• Certifications: ATEX, IECEx, UL, and local standards ensure compliance with hazardous area regulations. These models provide safe, reliable, and flexible solutions for industrial power and signal distribution in explosive environments, with options for both standard and fully customized configurations .
