• Connection 1 - Connectable conductor materials: Copper|Aluminum
• Connection 1 - Connectable conductor materials (note): Terminating Aluminum Conductors
  WAGO Spring-Clamp Terminal Blocks are suitable for solid aluminum conductors up to 4 mm²/12 AWG if WAGO “Alu-Plus” Contact Paste 249-130 is used for termination.
  
  “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 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:
  2.5 mm² = 16 A
  4 mm² = 22 A
