Description
Double-deck terminal block, 281 Series, grayThis double-deck terminal block (item number 281-635/281-492) simplifies electrical installations. Strip lengths must be between 9 and 10 mm when connecting conductors to this double-deck terminal block. The double-deck terminal block also functions as a component terminal block with diode. This product features conductor terminals and utilizes CAGE CLAMP®. Our renowned universal connection known as CAGE CLAMP® is industry-leading when it comes to connection technology and electrical interconnections. This double-deck terminal block is suitable 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 |
