Ground terminal block, 280 Series, green-yellow Our ground terminal block (item number 280-837) makes connecting wires quick and easy. 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. This product features conductor terminals and utilizes CAGE CLAMP®. Our trusted universal connection known as CAGE CLAMP® is the industry standard when it comes to connection technology and electrical interconnections. This ground terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 2.5 mm². This through rail-mount terminal block is operated with an operating tool.
