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.

Connectable conductor materials (note)

Terminating Aluminum ConductorsWAGO spring clamp terminal blocks are suitable for solid aluminum conductors up to 4 mm²/12 AWG if WAGO œAlu-Plus� Contact Paste 249-130 is used for termination.œAlu-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 œAlu-Plus� Contact Paste.It is also possible to apply WAGO œAlu-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 A4 mm² = 22 A
