Cable Digitus DK-SCEC66-0100 6 mm² MC4 10 m Black Red

The DIGITUS Cable DK-SCEC66-0100 is a ready-to-use 10 m solar extension cable with pre-assembled MC4 plug and socket. Designed for photovoltaic systems, it has a 6 mm² tinned copper conductor for reliable current transmission and corrosion protection, XLPO insulation and a robust jacket suitable for permanent outdoor use. The cable supports high-voltage PV installations with a voltage tolerance of up to 1500 V DC and operates in temperatures from -40 °C to +85 °C.

Advantages

This solar extension cable combines low contact resistance (≤ 0.5 Ω) and tinned copper conductors to minimize power loss and ensure long-term conductivity. Pre-assembled MC4 connectors enable tool-free, quick connection on site. The XLPO insulation and PA66-reinforced, halogen-free plug materials provide UV, moisture and ozone resistance as well as mechanical durability. The sheath is flame-retardant to UL94 V-0 and the product meets CE and EN 50618 standards, EN 60332-1-2 (Eca) and EN 62852:2015, making it suitable for international PV applications.

Suitable for

• Connecting solar modules in string arrays
• Linking modules to inverters or combiner boxes
• DIY and professional rooftop or ground-mounted PV installations
• Extensions and repairs of existing DC wiring in PV systems

How to use

Route the cable following the shortest practical path between components while avoiding sharp edges and heat sources. Connect the MC4 plug to the module or cable with the corresponding MC4 socket, ensuring proper polarity (red = positive, black = negative). The pre-assembled connectors allow tool-free mating; verify secure locking of the MC4 contacts. After installation, secure the cable with suitable clamps or ties and check the connections and insulation resistance before energizing the system.

Recommendations

For safe operation, use this cable only in DC photovoltaic circuits within the specified ratings (30 A, ≤ 1500 V DC). Maintain correct polarity, avoid overbending beyond recommended radii, and perform regular visual inspections for damage, UV aging or wear. Follow local electrical codes and the inverter or module manufacturer's installation instructions.
