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, and aluminum conductors must first be cleaned with a blade then immediately be inserted into the clamping units filled with “Alu-Plus” Contact Paste.
It is also possible to apply WAGO “Alu-Plus” on the whole surface of the aluminum conductor before termination.additionally
Please note that the nominal currents must be adapted to the reduced conductivity of the aluminum conductors:
2.5mm² (14 AWG) = 16 A 4mm² (12 AWG) = 22 A
