What is the Wago 279-508?

Double-deck terminal block, 279 Series, operating tool

This double-deck terminal block (item number 279-508) 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 functions as a through terminal block. Featuring conductor terminals along with CAGE CLAMP®, this product outperforms the competition. Our reliable 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. The dimensions are (4 x 85 x 43.8) mm (width x height x depth). Depending on the type of conductor, this double-deck terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 1.5 mm².
