Terminating Aluminum ConductorsWAGO Spring-Clamp Terminal Blocks are suitable for solid aluminum conductors up to 4 mm2/12 AWG if WAGO “Alu-Plus” Contact Paste249-130is 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 bladeand then immediately inserted into the clamping units filled with “Alu-Plus” contact paste.It is also possible to apply WAGO “Alu-Plus”additionallyon 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 A4 mm2 = 22 A
