Kábel Digitus DK-SCEC64-0050 4 mm² MC4 5 m čierny červený

The Digitus DK-SCEC64-0050 4 mm² MC4 5 m Black Red is a ready-to-use solar cable extension for indoor and outdoor photovoltaic installations. It has pre-assembled MC4 plug and socket, a tinned copper conductor with 4 mm² cross-section, XLPO insulation and a robust jacket to resist UV, moisture, ozone and mechanical stress. With a rated current of 30 A and DC voltage rating up to 1500 V, the cable is suitable for connecting solar modules, inverters and other PV components.

Advantages

High conductivity and corrosion protection are provided by tinned copper conductors. The pre-assembled MC4 connectors allow tool-free, fast and safe connections. The cable is designed for high-voltage PV systems with a DC tolerance up to 1500 V and offers a wide operating temperature range from -40 °C to +85 °C. The jacket is flame-retardant according to UL94 V-0 and the design ensures low contact resistance (≤0.509 Ω) to minimise power loss. The construction is weatherproof and durable for permanent outdoor use and complies with CE, EN 50618, EN 60332-1-2 (Eca) and EN 62852:2015 standards.

Suitable for

• Connecting solar panels in residential and commercial PV systems
• Linking modules to inverters or combiner boxes
• Extension runs where a 5 m 4 mm² MC4 connection is required
• Permanent outdoor installations requiring UV- and weather-resistant cabling

How to use

Position the cable between the solar module and the inverter or between modules so that neither conductor is under mechanical strain. Connect the pre-assembled MC4 plug to the matching MC4 socket of the module or device until it locks; verify the connection is secure. Route the cable following local installation rules, avoiding sharp edges and hot surfaces. Ensure polarity is correct (red = positive, black = negative) and fasten the cable with suitable clamps or ties to prevent movement. Perform insulation and continuity checks as required by applicable standards before commissioning.

Recommendations

Use this 4 mm² MC4 5 m cable for runs requiring up to 30 A and up to 1500 V DC. For long-distance runs or higher current demands, evaluate larger conductor cross-sections. Store and install the cable away from prolonged exposure to extreme solvents or oils, and follow local electrical codes for PV installation and grounding.
