ATEX Junction Boxes: Securing Your Installations in Hazardous Areas

ATEX junction boxes are essential components for ensuring electrical continuity and the safety of installations in explosive atmospheres. Used in high-risk industrial environments (Zones 1, 2, 21, or 22), they enable the connection, protection, and distribution of electrical circuits while complying with ATEX directives and international certifications.

At A2S, we offer a complete range of ATEX enclosures, explosion-proof junction boxes, and Ex e junction boxes, designed to meet the requirements of the most demanding industries: oil & gas, chemical, offshore, energy, and food processing.

How to Choose the Right ATEX Junction Box for Your Application

Selecting an ATEX junction box for hazardous areas depends on several key technical criteria:

• ATEX zone classification: Zone 0, 1 or 2 (gas) / 20, 21 or 22 (dust)
• Type of protection: increased safety (Ex e), flameproof enclosure (Ex d), etc.
• Enclosure material: GRP (polyester), aluminium, or stainless steel for corrosive environments
• Ingress Protection rating (IP66, IP67…) to ensure waterproofing and durability
• Number of entries/exits and compatibility with your ATEX cable glands
• Internal configuration: terminal blocks, earthing, and accessories

Our team supports you in selecting and sizing the right ATEX enclosure solution, whether for a standard configuration or a custom-designed project.

Industrial Applications of ATEX Junction Boxes

Explosion-proof junction boxes are used across a wide range of critical industrial environments:

• Oil & gas installations (onshore / offshore)
• Chemical and petrochemical plants
• Energy production facilities
• Food processing industries exposed to combustible dust
• Processing and storage platforms

In these environments, choosing a reliable and certified ATEX enclosure is essential to ensure operator safety and continuity of operations.
