What is the Wago 280-837/999-950?
Ground terminal block, 280 Series, green-yellow
Our ground terminal block (item number 280-837/999-950) ensures effortless electrical installations. Strip lengths must be between 8 and 9 mm when connecting conductors to this ground terminal block. Ground terminal blocks connect directly to the mounting rail via an integrated contact foot. This creates an electrical and mechanical link between the electrical conductors and the mounting adapter. This product features conductor terminals and utilizes CAGE CLAMP®. Our reliable and maintenance-free CAGE CLAMP® connection makes it easy to connect all conductor types without having to prepare the conductor. For example, you don't need to crimp ferrules. This ground terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 2.5 mm².
This through rail-mount terminal block is operated with an operating tool.
