Connection of solid aluminum
wires
WAGO spring-clamp terminal blocks
are suitable for solid aluminum wires Ê
up to 4 mm
2
/ AWG 12 if WAGO con-
tact paste „Alu-Plus“ is used for the
connection.
Please take into account that the nomi-
nal currents must be adapted to the
reduced conductivity of the aluminum
wires:
2.5 mm2
/ AWG 14 = 16 A
4 mm2
/ AWG 12 = 22 A
Cleaning and greasing of the aluminum
conductor is no longer necessary. Use
the WAGO contact paste “Alu-Plus“
instead, which is directly injected into
the conductor introduction hole of
WAGO terminal block by means of the
handy syringe.
This allows the easy connection of solid
aluminum wires (in case of multipole ter-
minal blocks, also mixed with copper
conductors).
WAGO „Alu-Plus“
l automatically destroys the oxide film
during clamping
l prevents fresh oxidation at the
clamping point
l prevents electrolytic corrosion bet-
ween aluminum- and copper con-
ductors (in the same terminal block)
l offers permanent protection against
corrosion
It is, of course, also possible to apply
the WAGO „Alu-Plus“ directly on the
whole surface of the aluminum wire
before clamping.
