Description
N-disconnect terminal block, 781 Series, operating toolConnect conductors quickly and securely with this N-disconnect terminal block (item number 781-643). Strip lengths must be between 9 and 10 mm when connecting conductors to this N-disconnect terminal block. Featuring conductor terminals along with CAGE CLAMP®, this connector outperforms the competition. Our highly-rated and maintenance-free CAGE CLAMP® connection makes it easy to connect all types of conductors without having to prepare the conductor. For example, you don’t need to crimp ferrules. Depending on the conductor type, this N-disconnect terminal block is ideal 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 |
