Ground terminal block, 285 Series, green-yellow Our ground terminal block (item number 285-607) makes connections quick and easy. Conductors can only be connected to this ground terminal block if their strip length is 23 mm . 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. This product features conductor terminals and utilizes CAGE CLAMP®. Our highly-rated 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. Depending on the type of conductor, this ground terminal block is suitable for conductor cross sections ranging from 6 mm² to 35 mm². An operating tool is used to operate this through rail-mount terminal block.
