Easy electrical installations are guaranteed with this double-deck terminal block (item number 870-501). The double-deck terminal block also serves as a through terminal block. Ensure that the strip lengths are between 6 mm and 7 mm when connecting conductors to this double-deck terminal block. This product incorporates conductor terminals and utilizes CAGE CLAMP®. Our reliable and maintenance-free CAGE CLAMP® connection makes it easy to connect all conductor types without having to prepare the conductor. For example, you don't need to crimp ferrules. This double-deck terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 2.5 mm². It has two levels. You can connect two potentials using the four clamping points. The grey housing is made of polyamide (PA66) for insulation. These through rail-mount terminal blocks are mounted using DIN-35 rails
