H05RR-F 3G 2,75mm² - 1m supple cable

H05RR-F 3G 2.5mm² Flexible Cable - High Performance

The H05RR-F 3G 2.5mm² cable is a high-performance flexible electrical connection cable, designed with a black elastomer double jacket. With its three conductors, each with a cross-section of 2.5 mm², and its reinforced construction, this cable offers a particularly robust and durable solution for your demanding indoor and outdoor electrical installations.

Double elastomer jacket: reinforced protection

The main feature of the H05RR-F cable is its double elastomer sheath construction. This design offers superior mechanical and environmental protection compared with single-sheathed cables:

• First layer: Individual rubber insulation for each conductor
• Second layer: Black elastomer outer sheath enclosing the whole cable.

This double protection gives the cable exceptional resistance to mechanical aggression (abrasion, impact, crushing), bad weather and temperature variations. The black elastomer also guarantees excellent resistance to UV rays and the chemicals commonly found in industrial environments.

2.5 mm² cross-section: power and versatility

The 2.5 mm² cross-section per conductor makes this cable an ideal intermediate solution between lightweight cables (1.5 mm²) and high-power cables (4 mm² and more). This cross-section allows currents of up to around 20-25 A to be carried, depending on installation conditions, which corresponds to significant power ratings:

H05RR-F technical specifications

The H05RR-F cable differs from the H07RN-F in a number of technical features that make it a premium product for demanding applications:

Photovoltaic and solar energy applications

The H05RR-F 3G 2.5mm² cable is particularly suitable for photovoltaic installations requiring a robust and reliable connection on the alternating current (AC) side:

• Connection of single-phase inverters: Connection between inverter (3-5 kW) and main switchboard
• Powering microinverters: AC wiring for Enphase IQ, Hoymiles, APSystems (multi-panel installations)
• Connection of AC protection boxes: Connection between electrical protection and solar equipment
• Solar charging stations: Power supply for single-phase 3.7 kW wallboxes powered by photovoltaic surpluses
• Wiring for batteries and hybrid inverters: Robust AC connections for storage systems
• Powering outdoor equipment: solar pumps, autonomous lighting, automatic controls, etc.

Professional applications

In addition to photovoltaics, H05RR-F 3G 2.5mm² cable is widely used in many professional sectors thanks to its exceptional robustness:

• Industry: powering machine tools, production equipment, electric motors, etc.
• Construction: Electrical extension leads, power supply for hand-held power tools
• Events: Temporary cabling for shows, concerts, fairs and exhibitions
• Agriculture: Power supply for pumps, irrigation systems, stabling equipment
• Boating: Electrical connections resistant to humidity and sea spray
• Mechanical workshops: Resistance to oils, greases and demanding environments

Electrical compliance and safety

H05RR-F complies with harmonised European standards for flexible cables, guaranteeing safe use:

Installation and conductor marking

The exceptional flexibility of the H05RR-F cable (class 5) makes it very easy to install, even in confined spaces or on routes with many bends. The three conductors are clearly identifiable by their standardised colour code:

• Blue: Neutral conductor (N)
• Brown or Black: Phase conductor (L)
• Green-Yellow: Protective earth conductor (PE)

The double elastomer sheath facilitates clean stripping and connection to terminals, dominos, sockets or connectors. The cable can be installed on the surface, in a trunking, in cable trays, or even buried in a protective conduit, depending on the needs of your installation.

Advantages of H05RR-F 3G 2.5mm² cable

Difference between H05RR-F and H07RN-F

It's important to understand the differences between these two types of flexible cable so you can choose the one best suited to your application:

H05RR-F is recommended for applications requiring greater robustness and a longer service life, while H07RN-F is perfectly suited to standard domestic uses.

Complementing your photovoltaic installation

As part of a complete photovoltaic installation, the H05RR-F 3G 2.5mm² cable is ideal for AC connections requiring greater robustness. It is particularly recommended for installations subject to severe mechanical or environmental stress.

For connections on the direct current (DC) side between solar panels and inverter, use specific solar cables designed to withstand the stresses of direct current and prolonged outdoor conditions.

To find out more about solar installation cabling and understand the different cross-sections required depending on distance and power, consult our detailed connection diagrams available on our website.

Installation precautions

Although the H05RR-F cable is particularly robust and suitable for outdoor use, we recommend protecting it in areas subject to pedestrian or vehicular traffic or extreme mechanical stress. For underground installations, it is essential to use suitable protective conduit (ICD, ICTA or TPC sheath depending on the application) and to comply with regulatory burial depths.

Check that the connections to the terminals are correctly tightened to the torque recommended by the equipment manufacturer. Insufficient tightening can lead to overheating and energy loss, while overtightening can damage flexible conductors.

Packaging and ordering

This H05RR-F 3G 2.5mm² cable is sold by the linear metre, allowing you to order exactly the length you need for your project without wastage. Each unit ordered corresponds to 1 metre of cable. For longer lengths, simply indicate the quantity required in your basket (example: quantity 20 = 20 metres of cable supplied in a single continuous length).
