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
