Cabo Digitus DK-SCEC66-0150 6 mm² 15 m MC4 preto vermelho

The DIGITUS Cable DK-SCEC66-0150 is a ready-to-use solar extension cable with pre-assembled MC4 plug and socket, designed for indoor and outdoor photovoltaic installations. With a conductor cross-section of 6 mm², a length of 15 m and a DC voltage rating up to 1500 V, the cable supports high-voltage PV systems while offering corrosion-resistant tinned copper conductors and XLPO insulation with a robust PA66 outer jacket.

Advantages

The cable provides high conductivity and corrosion protection thanks to tinned copper conductors and ensures low contact resistance (≤ 0.5 Ω) for minimal power loss. It is suitable for continuous outdoor use with UV, moisture and ozone resistance, and its flexible design allows easy routing even with tight radii. Pre-assembled MC4 connectors enable tool-free, fast connection. The jacket and insulation are flame-retardant (UL94 V-0) and the product complies with CE and relevant EN standards for international use.

Suitable for

• Connecting solar modules to inverters or combiner boxes
• Extending PV strings in residential and commercial installations
• DIY solar projects and professional PV system installations
• Outdoor and rooftop photovoltaic applications

How to use

Route the pre-assembled cable between solar modules, combiner boxes or inverters ensuring correct polarity (red = positive, black = negative). Secure the cable along its path to avoid mechanical strain and maintain the minimum bending radius. Connect the MC4 plug and socket by aligning and pushing until they click; verify the connection is locked. Follow local electrical codes and switch off PV circuits before making or breaking connections.

Recommendations

For long-term performance, inspect connections periodically for corrosion or damage, avoid sharp bends that exceed the cable's minimum bending radius, and use appropriate clamps or cable ties to relieve mechanical stress. Ensure installation complies with applicable standards and the inverter manufacturer's guidelines.
