Ground terminal block, 281 Series, CAGE CLAMP® Easily, quickly and safely connect conductors with this ground terminal block (item number 281-907/999-950). Strip lengths must be between 9 and 10 mm when connecting conductors to this ground terminal block. Our ground terminal blocks create a direct connection between the mounting rail and the electrical conductors thanks to an integrated mounting foot. This connection ensures both electrical and mechanical stability between the 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. Depending on the type of conductor, this ground terminal block is ideal 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.
