Cable Digitus DK-SCEC66-0010 6 mm² MC4 Connector 1m Black Red

Safe, efficient and ready for immediate use, the Digitus DK-SCEC66-0010 solar extension cable with pre-assembled MC4 connectors is a plug-and-play solution for indoor and outdoor photovoltaic installations. The 1 m cable has a 6 mm² tinned copper conductor, XLPO insulation and a robust jacket to ensure low electrical losses and long-term resistance to environmental stress.

Advantages

The cable offers high conductivity and corrosion protection thanks to tinned copper conductors with a 6 mm² cross-section. Pre-assembled MC4 connectors enable fast, tool-free connections. It supports high-voltage PV systems with a DC voltage rating up to 1500 V and maintains performance in a wide temperature range from -40 °C to +85 °C. The jacket and insulation are UV-, moisture- and ozone-resistant, the sheath is flame-retardant to UL94 V-0, and the construction provides low contact resistance (≤ 0.5 Ω) for minimal power loss.

Suitable for

• Connecting solar modules in residential or commercial PV arrays
• Extending PV strings or linking panels to inverters
• DIY solar projects and professional installations requiring MC4 interfaces
• Outdoor and rooftop installations exposed to UV and weather

How to use

Install the Digitus DK-SCEC66-0010 by plugging the pre-assembled MC4 connectors into the matching MC4 sockets of the solar panels or system components. Ensure connectors click into place and verify polarity (black = negative, red = positive). Route the cable avoiding sharp edges and tight bends; secure with appropriate clamps if required. Verify system voltage and rated current compatibility before energising the array.

Recommendations

For long-term outdoor performance, avoid prolonged mechanical abrasion and chemical exposure; inspect connectors and cable jacket periodically for damage and replace if signs of wear, corrosion, or compromised insulation appear.
