Hensel FK 1616 Fire-Resistant Surface-Mounted Junction Box E90 IP65 5x16mm2

The Hensel FK 1616 is a professional-grade, fire-resistant surface-mounted junction box engineered to maintain electrical circuit integrity under extreme conditions. Certified for E90 fire resistance, this enclosure ensures that critical safety systems remain operational for at least 90 minutes during a fire. With an IP65 ingress protection rating, the unit is effectively shielded against dust and water jets, making it suitable for both indoor and protected outdoor installations in industrial and commercial environments.

Advantages

This junction box offers exceptional reliability for safety-critical electrical infrastructure. Its robust construction provides high mechanical stability, while the specialized fire-resistant material prevents the spread of flames and maintains electrical continuity. The design facilitates efficient cable management for 5x16mm2 conductors, ensuring that connections remain secure even under thermal stress. The IP65 rating provides peace of mind in environments where moisture or dust could otherwise compromise electrical components.

Suitable for

• Emergency lighting systems
• Fire alarm and detection systems
• Smoke extraction equipment
• Critical power supply circuits in public buildings
• Industrial facilities requiring E90 fire safety standards

When it may not be suitable

This junction box is not intended for use in areas subject to permanent submersion or high-pressure water cleaning, as it is rated for IP65 protection rather than full waterproofing. It is also not designed for hazardous zones where explosion-proof equipment is specifically required.

Key specifications

• Fire resistance class: E90
• Protection rating: IP65
• Conductor capacity: 5x16mm2
• Mounting type: Surface-mounted
• Material: High-grade fire-resistant thermoplastic

How to use

The Hensel FK 1616 should be installed by a qualified electrician in accordance with local fire safety regulations and electrical codes. The box is mounted directly onto a wall or ceiling surface using the provided fixing points. Cables must be inserted through appropriate cable glands that maintain the IP65 integrity of the enclosure. Ensure that all connections are tightened to the specified torque to prevent overheating and to maintain the integrity of the fire-resistant circuit.

What to consider before purchase

• Verify that the E90 fire resistance rating meets the specific requirements of your building project.
• Ensure the cable cross-section of 16mm2 is compatible with your electrical system design.
• Confirm that the installation environment is compatible with the IP65 protection rating.
• Check local regulations regarding the use of fire-resistant junction boxes in your jurisdiction.

Usage recommendations: Always use certified fire-resistant cables in conjunction with this junction box to ensure the full E90 system integrity is maintained during an emergency.
