Unique - the SUNCLIX connection system for photovoltaics

DC plug-in connectors

Safety, durability, and fast assembly are the requirements placed on DC plug-in systems. With SUNCLIX plug-in connectors, conductor connection is more efficient than ever before.

SUNCLIX DC plug-in connectors that can be assembled

One-piece DC plug-in connectors from Phoenix Contact can be used to cable your PV modules quickly and easily. Simply insert the stripped conductor in the spring terminal block, close the spring, and you're done! Thanks to SUNCLIX, it couldn't be easier. Minimize power loss with SUNCLIX plug-in connectors for 16 mm² conductors and corresponding 16 mm² cables.

Versions for conductor cross sections from 2.5 to 16 mm²
Patented spring connection
Voltage up to 1100 V or 1500 V
IP65/IP68 protection
According to DIN EN 50521
UL approval in preparation

Quick and easy assembly

The one-piece DC plug-in connectors with spring technology can be connected quickly, easily, and without special tools:

Insert the stripped PV conductor.
Press down on the spring and snap in.
Tighten the screw connection. The unique spring technology ensures reliable and long-term stable contacting of the conductors.
The field and device plug-in connector locking is very secure: inadvertent removal of the plug from the device is not possible. The connection can only be released using a screwdriver.
