Enjoy seamless electrical installations with this triple-deck terminal block (item number 280-549). The triple-deck terminal block also functions as a through terminal block. Ensure that the strip lengths are between 8mm and 9mm 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. Depending on the conductor type, this triple-deck terminal block is ideal for conductor cross sections ranging from 0.08mm² to 2.5mm². It comes with three levels and six clamping points that you can use to connect three potentials. The gray housing is made of polyamide (PA66) for insulation. These through rail-mount terminal blocks are mounted using DIN-35 rails.
