Explosion-proof outdoor power distribution boxes suitable for hazardous zones are available in GRP, aluminium, and stainless steel, with ATEX and IECEx certifications for Zones 1, 2, 21, and 22.

Key Models and Materials

• GRP (Glass Fibre Reinforced Polyester) Boxes: The HTB1P series offers high corrosion and UV resistance, suitable for chemical, petrochemical, and power generation industries. They support terminals up to 16 mm² and can be configured for intrinsically safe circuits, making them ideal for outdoor hazardous environments (Zones 1, 2, 21, 22) .
• Aluminium and Stainless Steel Enclosures: ROSE Systemtechnik provides aluminium and stainless steel explosion-proof enclosures with ATEX and IECEx certifications. Aluminium housings are robust, easy to machine, and available in Ex i (intrinsically safe) and Ex e (increased safety) variants. Stainless steel enclosures offer high durability and resistance to harsh outdoor conditions .
• Flameproof and Modular Enclosures: Supermec's EJB and CSD series are designed for chemical plants, offshore platforms, and refineries. These enclosures support power distribution, monitoring, and signaling in hazardous atmospheres, with long-term durability and corrosion resistance .
• Comprehensive Power Handling Systems: BARTEC offers modular low- and medium-voltage power distribution solutions with Ex d (flameproof), Ex e (increased safety), and Ex i (intrinsically safe) options. Their systems include control and signaling devices, motor control, and fully integrated services from consulting to maintenance, suitable for Zone 1 and other hazardous areas .

Certifications and Compliance

• ATEX and IECEx: Most models are certified for use in explosive atmospheres, ensuring compliance with international safety standards.
• Zone Ratings: Suitable for gas (Zones 1 and 2) and dust (Zones 21 and 22) hazardous areas.
• Temperature and Environmental Resistance: Enclosures are designed to withstand UV exposure, corrosion, and extreme temperatures, making them suitable for outdoor installations .

Considerations for North Macedonia

• While local suppliers may vary, these international brands typically provide shipping and technical support for industrial projects in North Macedonia.
• Selection should consider the specific hazardous zone, environmental conditions, and required power distribution capacity.
• Customizable modular designs allow integration of control, signaling, and motor management systems for industrial applications. These options provide safe, durable, and certified solutions for outdoor power distribution in hazardous areas, ensuring compliance with international safety standards and long-term operational reliability.
