FLEXIBLE CONNECTION CABLE IN BLACK NEOPRENE

H07RN-F ECA 4G6 mm² 450/750V - Flexible Neoprene Connection Cable

The H07RN-F ECA 4G6 mm² cable is a flexible black neoprene electrical connection cable designed to meet the requirements of photovoltaic and residential electrical installations. Its neoprene sheath makes it exceptionally resistant to harsh weather conditions, humidity and UV rays, ensuring optimum durability indoors and outdoors.

Main applications

This cable is ideal for :

• Connecting three-phase inverters: Particularly suitable for 6 to 10 kW photovoltaic inverters requiring a three-phase earthed connection.
• AC connections: Connection between the inverter and the main switchboard
• Residential electrical installations: Three-phase distribution for high-consumption appliances
• Demanding environments: Protected outdoor installations, equipment rooms, passageways in ducts, etc.

Advantages of H07RN-F cable for photovoltaic installations

Optimum flexibility: H07RN-F 4G6 mm² cable offers excellent flexibility, making it much easier to handle and install, particularly in confined spaces or when passing through ducts. This reduces installation time and minimises the risk of damage on site.

Weather-resistant: The neoprene sheath provides long-lasting protection against humidity, temperature variations (-25°C to +60°C) and UV rays. This robustness guarantees the long-term reliability of your photovoltaic installation, even in harsh weather conditions.

Enhanced safety: With its ECA fire rating and compliance with current European standards, this cable meets the most stringent requirements in terms of electrical safety. The earth conductor (4th conductor) ensures effective earthing, essential for protecting people and equipment.

💡 Expert advice: To guarantee the safety and performance of your installation, it is essential to comply with the recommended cable cross-sections depending on the power of your inverter and the length of the cable. The 4G6 mm² cable is perfect for inverters up to 10 kW with cable lengths of up to 20-25 metres.

Sizing and choice of cross-section

The choice of cable cross-section is crucial for limiting energy losses and ensuring the safety of your installation. For a H07RN-F 4G6 mm² cable:

• Length up to 15 m: three-phase UPS up to 10 kW
• Length 15-25 m: Three-phase UPS up to 8 kW
• Over 25 m: Choose a larger cross-section (10 mm²) or consult our voltage drop calculator.

To validate the sizing of your cables and calculate the voltage drop of your installation, consult our free calculator available in the Wattuneed toolbox.

Installation and use

Thanks to its flexibility, the H07RN-F 4G6 mm² cable is easy to install:

1. Preparation: Calculate the exact length required, allowing a 10-15% margin for connections.
2. Stripping: Use suitable stripping pliers to avoid damaging the copper conductors.
3. Connection: Follow the colour code (blue=neutral, brown/black/grey=phases, green-yellow=earth) and tighten the terminals correctly.
4. Mechanical protection: Although strong, the cable must be protected from significant mechanical stress (passing vehicles, impacts).
5. Fixing: Use clamps spaced 30-40 cm apart to avoid sagging.
