Description
Power distribution disconnect terminal block, 781 Series, operating toolOur power distribution disconnect terminal block (item number 781-623) ensures effortless electrical installations. Strip lengths must be between 9 and 10 mm when connecting conductors to this power distribution disconnect terminal block. Featuring conductor terminals along with CAGE CLAMP®, this product outperforms the competition. Our celebrated universal connection known as CAGE CLAMP® is industry-leading when it comes to connection technology and electrical interconnections. Depending on the type of conductor, this power distribution disconnect terminal block is designed for conductor cross sections ranging from 0.08 mm² to 4 mm².

| 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 “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 A4 mm² = 22 A |
