Ground terminal block, 870 Series, green-yellow This ground terminal block (item number 870-907) is designed for quick and easy connections. Conductors should only be connected to this ground terminal block if their strip length is between 6 and 7 mm . 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 highly-rated 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 2.5 mm². This mini rail-mount terminal block is operated with an operating tool.
