Technical Information
“Alu-Plus” Contact Paste
Terminating Aluminum Conductors
WAGO spring clamp terminal blocks are suit-
able for solid aluminum conductors to
4 mm²/12 AWG WAGO “Alu-Plus” Contact
Paste used for termination.
“Alu-Plus” Contact Paste Advantages:
• Automatically destroys the oxide film during
clamping.
1 Aluminum conductors per IEC 61545 standard, Class B,
“Alloy 1370” with 180 N/mm² tensile strength and 1
… elongation
Standard values: 180 MPa tensile strength, 4%
elongation (per 615.5 mm² (14 AWG) A
4 mm² (12 AWG) A
Press plunger down until the “Alu-Plus” has filled both
entry holes.
WAGO Rail-Mount Terminal Blocks (up mm²/12 AWG)
For each conductor entry: Insert nozzle the “Alu-Plus”
syringe every open conductor entry hole (one after the
other).1)
WAGO Lighting Connectors
Push nozzle the “Alu-Plus” syringe first into the circular
entry and then into the square conductor entry hole the
WAGO Lighting Connector.
It also possible apply WAGO “Alu-Plus”
additionally the whole surface the alu-
minum conductor before termination.
• Prevents electrolytic corrosion between
aluminum and copper conductors (in the
same terminal block).
WAGO “Alu-Plus” the syringe offers higher degree of
reliability and cleanliness when terminating solid alumi-
num conductors.
Note: Not suitable for higher temperature applications!
Press plunger down until “Alu-Plus” has filled all conductor
entry holes.29

Please note that the nominal currents must

Using terminal blocks with CAGE CLAMP®
Spring Pressure Connection Technology,
aluminum conductors must first cleaned
with blade and then immediately be
inserted into the clamping units filled with
“Alu-Plus” Contact Paste.4. Filling quickly performed selected
WAGO connectors and terminal blocks (see pictures).
• Provides long-term protection against cor-
rosion.
• Prevents fresh oxidation the clamping
