WAGO “Alu-Plus” contact paste also WAGO “Alu-Plus” in the syringe
allows WAGO spring-clamp terminal offers a higher degree of reliability
blocks to be reliably terminated with solid and cleanness when connecting
aluminum conductors up to 4 mm solid aluminum conductors.

performed on WAGO
WAGO “Alu-Plus” Contact Paste PCB terminal trips:
• prevents fresh oxidation at the clamp-
ing point.
• prevents electrolytic corrosion between
aluminum and copper conductors.
• offers permanent protection against
corrosion.

Using terminal blocks with CAGE
CLAMP Spring Pressure Connection
®
Technology, aluminum conductors must
first be cleaned and then immediately be
inserted into the clamping units filled with
WAGO “Alu-Plus” contact paste. 1. Push nozzle of the “Alu-Plus” syringe
into every conductor entry hole.
It is, of course, also possible to apply
WAGO “Alu-Plus” additionally on the
whole surface of the aluminum conductor
before termination.

Also note that the nominal currents must
be adapted to the reduced conductivity
of the aluminum conductors:
2.5 mm (14 AWG) = 16 A

4 mm (12 AWG) = 22 A

2. Press plunger down until “Alu-Plus” has
filled each of these entries.

of 90–180 N/mm and elongation

of 1–4 %.
Standard values: 90–180 MPa tensile
