What is the Wago 279-904?

Through terminal block, 279 Series, blue

Quick and easy connections are guaranteed with this through terminal block (item number 279-904). Ensure that the strip lengths are between 8 and 9 mm when connecting conductors to this through terminal block. Whether for industrial or building applications, you can use our through terminal blocks to connect electrical conductors quickly and safely. We offer variants for both classic through-wiring and potential distribution. Featuring conductor terminals along with CAGE CLAMP®, this connector delivers reliable performance. Our CAGE CLAMP® connection offers 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. Dimensions: (4 x 52 x 31.5) mm (width x height x depth). This through terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 1.5 mm².

This through rail-mount terminal block is operated with an operating tool.
