The H05RR-F 3G 2.5mm² flexible cable is a high-performance electrical connection cable designed for demanding installations. Its unique black elastomer double-jacket construction offers exceptional mechanical and environmental protection, far superior to standard single-jacket cables.
With its three 2.5 mm² conductors (phase, neutral and earth), this cable can carry up to 5750W of 230V single-phase power, making it ideal for connecting 3 to 5 kW photovoltaic inverters, micro-inverters, single-phase charging stations or any electrical equipment requiring a robust, reliable connection.
The double elastomer sheath gives the cable outstanding resistance to impact, abrasion, crushing, weathering, UV rays and chemicals. Particularly flexible (class 5), H05RR-F is easy to handle, even in confined spaces. It can withstand a wide temperature range (-25°C to +60°C) and is suitable for both indoor and outdoor use.
Applications: connection of photovoltaic inverters and microinverters, connection of AC boxes, power supply for recharging stations, industrial cabling, professional extenders, worksite installations.
Sold by the linear metre. HD 21 / IEC 60245 compliant.

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.
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:
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.
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:
The H05RR-F cable differs from the H07RN-F in a number of technical features that make it a premium product for demanding 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:
To correctly size your cables according to your installation and avoid voltage drops, use our voltage drop calculator available free of charge in the Wattuneed toolbox.
In addition to photovoltaics, H05RR-F 3G 2.5mm² cable is widely used in many professional sectors thanks to its exceptional robustness:
H05RR-F complies with harmonised European standards for flexible cables, guaranteeing safe use:
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:
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.
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.
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.
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.
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).
