Advantages

This junction box offers exceptional durability and thermal resistance, meeting the stringent E90 fire resistance rating requirements. Its design facilitates secure cable management while preventing the spread of fire through the electrical installation. The enclosure is built to withstand harsh conditions, providing long-term reliability for emergency lighting, fire alarm systems, and other essential infrastructure that must remain operational during a fire emergency.

Suitable for

• Fire alarm and detection systems
• Emergency lighting installations
• Safety-critical power supply circuits
• Industrial and commercial building infrastructure

When it may not be suitable

This product is not intended for use in environments requiring explosion-proof certification or for installations exposed to constant submersion in water. It is specifically optimized for fire resistance rather than general-purpose outdoor use without additional protective measures.

Key specifications

• Fire resistance rating: E90
• Cable entries: 8xM25 and 2xM32
• Mounting type: Surface-mounted
• Application: Electrical circuit integrity maintenance

How to use

The junction box should be installed by qualified personnel in accordance with local electrical regulations. Secure the enclosure to a fire-rated surface using appropriate mounting hardware. Insert cables through the designated M25 and M32 entries, ensuring that all cable glands are properly tightened to maintain the integrity of the enclosure. Ensure that all internal connections are made using fire-resistant terminal blocks to comply with safety standards.

What to consider before purchase

• Verify the compatibility of cable diameters with the provided M25 and M32 entries.
• Ensure the mounting surface meets the required fire resistance standards for the installation.
• Confirm that the total number of cable entries meets the requirements of your specific electrical layout.

Usage recommendations

Always use certified fire-resistant cables and connectors in conjunction with this junction box to ensure the full E90 performance rating is maintained throughout the entire electrical circuit.
