Note on connectable conductor materials Terminating Aluminum Conductors

WAGO spring clamp terminal blocks are suitable for solid aluminum conductors up to 4 mm²/12 AWG if WAGO “Alu-Plus” Contact Paste is used for termination.


“Alu-Plus” Contact Paste Advantages:

Automatically destroys the oxide film during clamping.

Prevents fresh oxidation at the clamping point.

Prevents electrolytic corrosion between aluminum and copper conductors (in the same terminal block).

Provides long-term protection against corrosion.



Using terminal blocks with CAGE CLAMP® Spring Pressure Connection Technology, aluminum conductors must first be cleaned with a blade and then immediately be inserted into the clamping units filled with “Alu-Plus” Contact Paste.


For spring clamp connections with PUSH WIRE® connection technology, WAGO recommends that the aluminum conductor first be cleaned and then immediately inserted into the clamping unit filled with “Alu-Plus” contact paste.


It is also possible to apply WAGO “Alu-Plus” additionally on the whole surface of the aluminum conductor before termination.


Please note that the nominal currents must be adapted to the reduced conductivity of the aluminum conductors::

2.5 mm² = 16 A

4 mm² = 22 A

Solid conductor 0.08 … 4 mm² / 28 … 12 AWG
