For spring clamp connections with PUSHWIRE 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-Plusadditionallyon 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:
2.5mm = 16A
4mm = 22A
