Καλώδιο Digitus DK-SCEC64-0030 4 mm² MC4-Βύσμα 3 m Μαύρο Κόκκινο

Digitus DK-SCEC64-0030 is a ready-to-use 3 m solar extension cable with pre-assembled MC4 connectors designed for connecting photovoltaic modules, inverters and other PV components. The cable has a 4 mm² tinned copper conductor and is intended for reliable power transmission in solar energy systems, with insulation and jacket materials providing resistance to UV, moisture, ozone and mechanical stress.

Advantages

The cable offers high conductivity and corrosion protection due to tinned copper conductors with a 4 mm² cross-section, along with low contact resistance (≤ 0.509 Ω) to minimise power losses. Pre-assembled MC4 connectors enable tool-free, fast and safe plug-and-play installation. It supports high DC voltages (up to 1500 V DC dielectric strength, 1000 V rated), withstands temperatures from -40 °C to +85 °C and features a flame-retardant sheath (UL94 V-0). The construction is weatherproof and flexible for permanent outdoor use and tight radii.

Suitable for

• Extending solar panel connections on rooftop and ground-mounted PV arrays
• Connecting solar modules to inverters and combiner boxes
• DIY solar projects and professional photovoltaic installations

How to use

Verify system voltage and polarity before installation. Route the cable between modules, inverters or junction points observing bending radii and securing it to avoid mechanical strain. Connect the MC4 plug to the corresponding MC4 socket ensuring proper engagement until they click; use the pre-assembled connectors to avoid additional tooling. Confirm electrical connections and insulation integrity before energising the PV system.

Recommendations

For safe and durable operation, use the cable within the specified temperature and voltage ranges, follow local electrical codes and manufacturer guidance, and perform periodic inspections for UV or mechanical damage. Do not exceed the rated current and ensure correct polarity when connecting modules and inverters.
