Termination of aluminum conductors
WAGO spring-clamp terminal blocks are suitable for solid
aluminum conductors 1 up to 4 mm²/AWG 12 if contact
paste “Alu-Plus” is used for the termination.
“Alu-Plus”
· 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 connector)
· Offers permanent protection against corrosion

Connection Technology, aluminum conductors must first be WAGO rail-mount terminal blocks
cleaned and then immediately be inserted into the clamp- (only up to 4 mm²/AWG 12)
