Ground terminal block, 279 Series, CAGE CLAMP® This ground terminal block (item number 279-907) is designed for simple and secure connections. Strip lengths must be between 8 and 9 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. Featuring conductor terminals along with CAGE CLAMP®, this connector is highly versatile. Our reliable and maintenance-free CAGE CLAMP® connection makes it easy to connect all types of conductors without having to prepare the conductor. For example, you don't need to crimp ferrules. Dimensions: (4 x 54 x 31.5) mm (width x height x depth). Depending on the type of conductor, this ground terminal block is designed for conductor cross sections ranging from 0.08 mm² to 1.5 mm². An operating tool is used to operate this through rail-mount terminal block.
