<h2>Ground terminal block, 281 Series, green-yellow</h2><br/><br/>Quick and easy connections are guaranteed with this ground terminal block (item number 281-637/999-950). Strip lengths must be between 9 and 10 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 connection between the electrical conductors and the mounting adapter. Featuring conductor terminals along with CAGE CLAMP®, this connector outperforms the competition. 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. Depending on the type of conductor, this ground terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 4 mm².<br/><br/><h3></h3><br/><br/>An operating tool is used to operate this through rail-mount terminal block.<br/>
