Connectable conductor materials (note)
Terminating Aluminum Conductors (not for use in North America)WAGO Spring-Clamp Terminal Blocks are also suitable for solid aluminum conductors up to 4 mm2/12 AWG if WAGO 鈥淎lu-PlusContact Paste249-130is used for termination.鈥淎lu-PlusContact 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 鈥淎lu-Pluscontact paste.For spring clamp connections with PUSH WIRE®connection technology,WAGO recommends that the aluminum conductor first be cleanedand then immediately inserted into the clamping unit filled with 鈥淎lu-Pluscontact paste.It is also possible to apply WAGO 鈥淎lu-Plus鈥漚dditionallyon 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
