Ground terminal block, 284 Series, CAGE CLAMP® Our ground terminal block (item number 284-687) makes connecting wires quick and easy. Conductors should only be connected to this ground terminal block if their strip length is between 12 and 13 mm . Our 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. 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. Depending on the conductor type, this ground terminal block is suitable for conductor cross sections ranging from 0.2 mm² to 10 mm². This through rail-mount terminal block is operated with an operating tool.
