Cabo Digitus DK-SCEC66-0050 6 mm² MC4 5 m Preto Vermelho

The Digitus DK-SCEC66-0050 is a ready-to-use solar cable extension with pre-assembled MC4 plug and socket, designed for reliable DC connections in photovoltaic systems. With a 6 mm² tinned copper conductor and 5 m length, the cable supports modern high-voltage PV installations up to 1500 V DC. XLPO insulation and a robust jacket provide resistance to UV, moisture, ozone and mechanical stress, while flame-retardant properties (UL94 V-0) and low contact resistance ensure safe and efficient power transmission.

Advantages

High conductivity and corrosion protection are provided by the tinned copper conductor with a 6 mm² cross-section. Pre-assembled MC4 connectors allow tool-free, fast and secure connections. The cable is rated for voltages up to 1500 V DC and operates in temperatures from -40 °C to +85 °C. It is flame-retardant according to UL94 V-0, has low contact resistance (≤ 0.5 Ω) for minimal power loss, and meets international standards including EN 50618, EN 60332-1-2 (Eca) and EN 62852:2015. The flexible design and weatherproof construction make it suitable for permanent outdoor use.

How to use

Install the cable by connecting the pre-assembled MC4 plug and socket to the corresponding MC4 connectors on the solar modules, inverters or junction boxes. Ensure connectors are fully engaged and locked; verify polarity (black = negative, red = positive) before energizing. Route the cable avoiding sharp edges and tight bends, observe the specified minimum bending radius, and secure the cable to prevent mechanical strain. Follow local electrical codes and the inverter or module manufacturer’s installation instructions when integrating the cable into the PV system.

Recommendations

For long-term outdoor performance, route the cable where it is protected from excessive mechanical wear and minimize exposure to concentrated chemical agents. Periodically inspect connectors for corrosion or damage and replace the cable if insulation or connectors are compromised. Use only compatible MC4 components and observe system voltage/current limits (1500 V DC, 30 A).
