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, aluminum conductors must first be cleaned with a blade and then immediately be inserted into the clamping units filled with Alu-Plus Contact Paste. It is also possible to apply WAGO Alu-Plus additionally on the whole surface of the aluminum conductor before termination. Please note that the nominal currents must be adapted to the reduced conductivity of the aluminum conductors: 2.5mm (14 AWG) = 16 A 4mm (12 AWG) = 22 A Data Connection data Connection technology CAGE CLAMP Actuation type Operating tool Connectable conductor materials Copper Aluminum Solid conductor 0.08 2.5mm/ 28 12AWG Fine-stranded conductor 0.08 2.5mm/ 28 12AWG Strip length 8 9mm/ 0.31 0.35inch Total number of connection points 4 Total number of potentials 1 Number of levels 1 Type of wiring Front-entry wiring Note (conductor cross-section) 12 AWG: THHN, THWN Geometrical Data Width 5mm/ 0.197inch Height from upper-edge of DIN-35 rail 28mm/ 1.102inch Depth 75mm/ 2.953inch Subject to changes.
