Kaapeli Digitus DK-SCEC66-0030 6 mm² 3 m MC4 musta punainen

The DIGITUS Cable DK-SCEC66-0030 is a ready-to-use solar extension cable with pre-assembled MC4 plug and socket. With a 6 mm² tinned copper conductor, 3 m length and a rated voltage up to 1500 V DC, the cable is intended for reliable connections between solar modules, inverters and other PV components. The XLPO insulation and robust jacket provide protection against UV, moisture, ozone and mechanical stress, while the cable is suitable for permanent outdoor use and DIY or professional PV installations.

Advantages

High conductivity and corrosion protection are provided by tinned copper conductors with a 6 mm² cross-section. The pre-assembled MC4 connectors allow tool-free, fast and safe installation. The cable is rated for high-voltage PV systems up to 1500 V DC, withstands temperatures from -40 °C to +85 °C and has a flame-retardant sheath meeting UL94 V-0. Low contact resistance (≤ 0.5 Ω) minimises power losses, and compliance with CE, EN 50618, EN 60332-1-2 (Eca) and EN 62852:2015 ensures international approval and safety.

How to use

Route the cable between PV modules, inverters or junction boxes ensuring that bending radii are respected and the connectors are not stressed. Connect the MC4 plug to the corresponding MC4 socket on the mating component until the locking mechanism engages. Verify correct polarity (red = positive, black = negative) before making the final connection. Perform an insulation and continuity check according to local electrical codes and the inverter manufacturer's instructions prior to energising the system.

Recommendations

For long-term outdoor installations, secure the cable against mechanical strain and UV exposure with appropriate clamps or conduit, avoid sharp edges, and follow local installation standards. Use the cable within the specified temperature and voltage limits and ensure connectors are clean and fully locked before operation.
