Suitable for

• Emergency lighting systems
• Fire alarm and detection systems
• Smoke and heat extraction systems
• Safety-critical electrical installations in public buildings
• Industrial facilities requiring fire-rated cable protection

This junction box may not be suitable for applications requiring submersion in water or environments with high levels of chemical exposure that could degrade the housing material. It is also not intended for use in explosive atmospheres or areas where specialized explosion-proof enclosures are mandated by local safety regulations.

Key specifications

• Fire resistance class: E90
• Mounting type: Surface-mounted
• Dimensions: 150 mm x 117 mm x 68 mm
• Material: Halogen-free, fire-resistant plastic
• Protection rating: Suitable for fire-rated cable systems

Installation should be performed by qualified electrical personnel in accordance with local fire safety codes and manufacturer guidelines. The box should be securely mounted to a stable surface using appropriate fixings. Cables must be inserted through the provided entry points using certified fire-resistant cable glands to maintain the integrity of the enclosure. Ensure all internal terminals are tightened to the specified torque to prevent loose connections that could lead to overheating.

What to consider before purchase

• Verify the fire safety requirements of your specific building project
• Ensure compatibility with the fire-rated cables being used
• Confirm that the dimensions are sufficient for the number of terminals required
• Check that the mounting surface is capable of supporting the weight of the box and cables

For optimal performance, always use certified fire-resistant cable glands and ensure that the entire cable route complies with the E90 fire safety standard requirements. Regular inspection of the installation is recommended to ensure that no physical damage has compromised the enclosure.
