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.

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
