This ground terminal block (item number 280-637) streamlines wire connections, making them both quick and easy. WAGO's ground terminal blocks allow you to connect electrical conductors directly to the mounting rail thanks to an integrated contact foot. This connection ensures both electrical and mechanical stability between the conductors and the mounting adapter. Conductors can only be connected to this ground terminal block if their strip length is between 8mm and 9mm. This product features conductor terminals and utilizes CAGE CLAMP®. 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. This ground terminal block is suitable for conductor cross sections ranging from 0.08mm² to 2.5mm². It has one level. The single potential can connect using the three clamping points The green-yellow housing is made of polyamide (PA66) for insulation. An operating tool is used to operate this through rail-mount terminal block. These through rail-mount terminal blocks are mounted using DIN-35 rails.. Conductors made of copper, aluminum can be connected thanks to angled front-entry wiring.
