Our triple-deck terminal block (item number 870-551) simplifies electrical installations. The triple-deck terminal block also functions as a through terminal block. Strip lengths must be between 6 mm and 7 mm when connecting conductors to this triple-deck terminal block. This product features conductor terminals and utilizes CAGE CLAMP®. Our highly-rated 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 triple-deck terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 2.5 mm². It has three levels. You can connect three potentials using the six clamping points. The gray housing is made of polyamide (PA66) for insulation. These through rail-mount terminal blocks are mounted using DIN-35 rails.
