Power loss
Power loss (max.) Pl (max.) (note) When selecting glass cartridge fuses, make sure that the maximum power loss listed below is not exceeded. The power loss is determined according to IEC or EN 60947-7-3/VDE 0611-6 at 23°C. The temperature rise of the terminal block must be checked according to their application and mounting. Higher ambient temperatures represent an additional impact on miniature fuses. Therefore, in such applications, the rated current must be reduced if necessary. More details are available from the manufacturers.
Power loss Pl max. overload and short-circuit protection (individual arrangement) 2.5W
Power loss Pl max. overload and short-circuit protection (group arrangement) 1.6W
Power loss Pl max. short-circuit protection (individual arrangement) 4W
Power loss Pl max. short-circuit protection (group arrangement) 4W

Connection 1
Connection technology CAGE CLAMP®
Actuation type Operating tool
Connectable conductor materials Copper
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 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::
2.5 mm² = 16 A
4 mm² = 22 A

Solid conductor 0.08 … 4 mm² / 28 … 12 AWG
Fine-stranded conductor 0.08 … 4 mm² / 28 … 12 AWG
Strip length 9 … 10 mm / 0.35 … 0.39 inches
Wiring direction Front-entry wiring
