What is the Wago 880-904/999-940?

Through terminal block, 880 Series, blue

Our through terminal block (item number 880-904/999-940) makes connections quick and easy. Ensure that the strip lengths are between 8 and 9 mm when connecting conductors to this through terminal block. Whether for use in industry or building installations, our rail-mount through terminal blocks make it easy to quickly and securely connect electrical conductors. They’re perfect for either classic through-wiring or distributing potential, depending on the variant. This product features conductor terminals and utilizes CAGE CLAMP®. 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. Depending on the conductor type, this through terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 4 mm².

An operating tool is used to operate this through rail-mount terminal block.
