Ex Installation Accessories

What are Ex Installation Accessories?

Ex installation accessories are specialized components used alongside certified Ex equipment to ensure proper mechanical support, electrical connection, environmental sealing, and overall system safety in hazardous zones. Though small in size, these parts play a critical role in preserving the explosion protection of the entire installation. If not properly selected and installed, they can compromise the effectiveness of the system and even void Ex certifications.

These accessories are designed for use in ATEX Zone 1, Zone 2 (gas) and Zone 21, Zone 22 (dust) environments, and must meet the same stringent certification requirements as the primary Ex equipment they support.

Common types of Ex Accessories

A wide range of Ex installation accessories is available to support different types of equipment, environments, and installation needs. These typically include:

• Cable Glands: One of the most important Ex accessories, cable glands provide secure and flameproof entry for cables into Ex enclosures. They maintain the integrity of the enclosure and prevent the transmission of sparks or flames through cable openings. Available in various materials (e.g., brass, stainless steel, plastic), and sealing options depending on cable type and zone classification.

• Mounting Brackets and Plates: Used to securely fix Ex equipment to walls, poles, or machinery. These ensure stable installation, reduce vibration, and help maintain proper alignment and accessibility.

• Sealing Elements and Stopping Plugs: Used to seal unused cable entries or conduit openings in Ex enclosures. These accessories maintain the IP and Ex rating of a device and prevent contaminants or flammable materials from entering.

• Breather Drains and Drain Plugs: Prevent moisture build-up inside Ex enclosures, especially in outdoor or humid environments. Moisture accumulation can compromise insulation and safety, so managing condensation is vital for long-term reliability.

• Adapters and Reducers: Allow installers to connect accessories or conduits of different thread types or sizes while maintaining flameproof properties. This flexibility is often required in retrofits or system upgrades.

• Locknuts, Washers, and Earth Tags: Small but essential items for grounding, securing glands, and maintaining mechanical integrity. These support long-term durability and safety.

Why Ex Installation accessories matter

Selecting the right Ex accessories is not just about fitting parts together. These components:

• Ensure the full system remains ATEX/IECEx compliant.

• Prevent gaps or weaknesses that could lead to ignition sources.

• Help maintain IP ratings against dust and moisture.

• Support mechanical stability in harsh industrial conditions.

• Extend the life and safety of your electrical installation.

Without certified Ex installation accessories, even the best Ex-rated equipment can become unsafe. These items complete the system and ensure that safety certifications are upheld in real-world conditions.
