TT Cables N2XH-J Halogen-free Power Cable, 3 x 4 mm², B2ca, 500m

The TT Cables N2XH-J is a high-performance halogen-free power cable engineered for fixed electrical installations in environments where stringent fire safety regulations are mandatory. Featuring a robust construction with three conductors, each with a cross-section of 4 mm², this cable is designed to provide reliable power distribution while minimizing risks associated with fire hazards. Its halogen-free composition ensures that in the event of combustion, the cable does not release toxic gases or dense smoke, making it a critical component for modern infrastructure safety.

Advantages

The primary benefit of the TT Cables N2XH-J lies in its superior fire performance, certified under the B2ca classification. This rating indicates a high level of resistance to flame propagation and heat release, which is essential for protecting building occupants and structural integrity. Furthermore, the cable is designed for durability and ease of installation, featuring a flexible hose-like shape that simplifies routing through conduits and cable trays. Its halogen-free material properties also contribute to environmental safety, reducing the overall ecological impact compared to traditional PVC-insulated cables.

Suitable for

• Residential building electrical wiring
• Commercial office complexes and public buildings
• Industrial facilities requiring high safety standards
• Fixed installations in dry or damp indoor environments

This cable is not intended for direct burial in the ground or for applications requiring high mechanical resistance to external impacts. It is also not suitable for use in environments where the cable will be exposed to direct sunlight for extended periods without additional UV protection, as the outer sheath is primarily optimized for indoor fixed installations.

Key specifications

• Number of conductors: 3
• Conductor cross-section: 4 mm²
• Fire classification: B2ca
• Cable shape: Hose
• Color: Black
• Packaging length: 500 m

To install the TT Cables N2XH-J, ensure that the electrical circuit is de-energized before beginning any work. The cable should be routed through appropriate cable management systems such as conduits, trunking, or cable trays, ensuring that the minimum bending radius is respected to prevent damage to the internal conductors. Connections should be made using compatible terminals and connectors, ensuring that the insulation is stripped carefully to avoid nicking the copper conductors. Always verify that the installation complies with local electrical codes and fire safety regulations.

What to consider before purchase

• Verify the total length required for your project to ensure the 500m reel is sufficient.
• Confirm that the 4 mm² cross-section meets the current and voltage requirements of your specific electrical load.
• Check if the B2ca fire rating satisfies the specific building code requirements for your installation site.

For optimal performance and safety, it is recommended to have the installation performed by a certified electrician. Regularly inspect the cable runs for any signs of physical damage or environmental degradation, especially in areas where the cable might be subject to vibration or thermal stress.
