Description
Triple-deck terminal block, 280 Series, CAGE CLAMP®Convenient electrical installations are guaranteed with this triple-deck terminal block (item number 280-557). Conductors should only be connected to this triple-deck terminal block if their strip length is between 8 and 9 mm . The triple-deck terminal block also serves as a through terminal block as well as a ground terminal block. This product incorporates conductor terminals and utilizes CAGE CLAMP®. Our proven 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 triple-deck terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 2.5 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 |
