Ground terminal block, 284 Series, operating tool This ground terminal block (item number 284-907) is designed to connect conductors quickly and easily. Conductors should only be connected to this ground terminal block if their strip length is between 12 and 13 mm . Our ground terminal blocks directly connect 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. Featuring conductor terminals along with CAGE CLAMP®, this connector is highly versatile. 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 0.2 mm² to 10 mm². This through rail-mount terminal block is operated with an operating tool.
