Cable DELOCK 90974 DL4 solar cable 6 mm² 3 m red/black DC 1000 V male to female

DELOCK 90974 is a DL4 solar cable for transmitting DC power in photovoltaic systems. The cable has a 6 mm² copper core, a length of 3 m and dual red/black insulation. It comes with one DL4 male and one DL4 female connector and is suitable for DC systems up to 1000 V, providing a secure watertight connection for solar modules, charge controllers and inverters.

Advantages

The DL4 plugs and sockets feature a snap-in locking mechanism that prevents accidental disconnection and ensures a stable electrical contact. The cable is rated IP67 for dust and water protection, and the conductor and insulation materials allow operation across a wide temperature range from -40 °C to 90 °C.

Suitable for

When it may not be suitable

This cable is intended for low-voltage DC photovoltaic applications and is rated to a maximum of 1000 V. It is not suitable for AC mains wiring or applications that require higher voltage ratings. The connector pair is specifically DL4-compatible; adapters or different connector systems may be required to interface with non-compatible hardware.

Key specifications

How to use

Route the cable between the solar module and the target device (charge controller, inverter or junction point). Push the DL4 male and female connectors together until the snap-in mechanism locks; use the appropriate release tool when disconnection is required. Ensure polarity is observed (red = positive, black = negative) and that all connections are made with the system de-energised. Check seals and routing to maintain the IP67 protection and avoid sharp bends or mechanical stress on the cable.

What to consider before purchase

Recommendations

Install and terminate the cable following local electrical and safety regulations. Inspect connectors and insulation periodically for damage and ensure connections remain secure to preserve waterproofing and electrical performance.
