Item description

Note:
Terminating Aluminum Conductors

WAGO spring clamp terminal blocks are suitable for solid aluminum conductors up to 4mm²/12AWG if WAGO “Alu-Plus” Contact Paste is 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, 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
