Ground terminal block, 880 Series, green-yellow Our ground terminal block (item number 880-907/999-940) is the ideal way to connect conductors quickly and securely. Conductors can only be connected to this ground terminal block if their strip length is between 8 and 9 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 incorporates conductor terminals and utilizes CAGE CLAMP®. Our CAGE CLAMP® connection provides a dependable and maintenance-free way to connect all types of conductors. You do not need to prepare the conductor in any way, such as crimping ferrules. Depending on the conductor type, 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.
