Distribution terminal block, 284 Series, blue Error-free electrical installations are guaranteed with this distribution terminal block (item number 284-624). Conductors can only be connected to this distribution terminal block if their strip length is between 12 and 14 mm . Distribution terminal blocks offer a space-saving way to distribute potentials with just a single terminal block. Their clever design means larger conductor cross-sections can be connected on one side and several smaller conductor cross-sections on the other. They are also ideal for potential collection in addition to potential distribution. Featuring conductor terminals along with CAGE CLAMP® as well as a screw connection, this product outperforms the competition. 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. Screw-clamp connections can carry currents from a fraction of an ampere all the way up to several hundred amperes at low to moderate frequencies. Depending on the conductor type, this distribution terminal block is suitable for conductor cross sections ranging from 0.2 mm² to 10 mm² on one side and for conductor cross sections from 6 mm² to 35 mm² on the other side. This through rail-mount terminal block is operated with an operating tool.
