What is the Wago 279-509?

Double-deck terminal block, 279 Series, blue

Our double-deck terminal block (item number 279-509) simplifies electrical installations. Ensure that the strip lengths are between 8 and 9 mm when connecting conductors to this double-deck terminal block. The double-deck terminal block also serves as a through terminal block. This product features conductor terminals and utilizes CAGE CLAMP®. Our CAGE CLAMP® connection provides a proven and maintenance-free way to connect all types of conductors. You do not need to prepare the conductor in any way, such as crimping ferrules. The dimensions are (4 x 85 x 43.8) mm (width x height x depth). Depending on the conductor type, this double-deck terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 1.5 mm².
