Cable Digitus DK-SCIC6B-0500 50m 6mm² Black UV-resistant

The Digitus DK-SCIC6B-0500 is a 50 m, 6 mm² solar cable designed for reliable DC connections in photovoltaic installations. It supports rated voltages up to DC 1500 V (AC 1 kV) and features a tinned copper conductor with XLPO insulation and outer jacket for long-term outdoor use. The cable is UV-resistant, weatherproof, flame-retardant to EN 50618:2014 and rated for operation from -40 °C to +90 °C, making it suitable for module-to-inverter wiring and other PV system interconnections.

Advantages

This black UV-resistant cable combines a flexible, fine-stranded tinned copper conductor with durable XLPO insulation and jacket to provide low conductor resistance, good corrosion protection and high dielectric strength. It is flame-retardant according to EN 50618:2014, resistant to UV, ozone and weathering, and rated for a long service life of up to 25 years under typical PV conditions. The cable’s flexibility and abrasion resistance simplify installation for both professional and DIY applications.

How to use

Use the cable to run DC connections between solar modules, from modules to string combiners or inverters, and for any PV system wiring that requires a UV-resistant outdoor cable. Strip the outer jacket and insulation according to the connector or terminal manufacturer’s instructions, ensuring correct conductor preparation for crimping or clamping. Route and secure the cable to avoid sharp bends, mechanical damage and prolonged contact with heat sources. Observe local electrical regulations and install appropriate overcurrent protection and grounding where required.

Recommendations

For best long-term performance, avoid tight bending radii, protect cable runs from concentrated mechanical stress, and follow EN 50618 and local electrical codes for installation and maintenance. Use matching PV-rated connectors and check connections periodically for corrosion or damage.
