The device terminal blocks are available in nominal cross-sections of 4, 10, and 35 mm². The 4 mm² cross-section has block versions with 2, 3, 4, 6, and 12 positions. While the 10 mm² cross-section only has 2, 3, 4, and 5 positions. The device blocks can only be mounted via direct mounting, e.g., screwed onto the mounting panel. The individual blocks can be tested quickly and easily via the terminal screws. GE and G device terminal blocks Device terminal blocks The G and GE device terminal blocks feature the universal screw connection technology for connecting flexible and rigid conductors. The screw connection is maintenance-free due to the patented Reakdyn principle. In addition to the use of splicing protection in the form of ferrules, the screw connection also enables multi-conductor connections in just one terminal point. In contrast to the FIX distribution blocks, the terminal points of the G device terminal blocks are not bridged with each other. The GE 10/2-BA BU block is the exception in the device terminal block range. The other device connection blocks thus carry individual potentials next to each other. Manual bridging is also not feasible here, as the blocks do not have special function shafts due to their compact design. This means that the blocks can only be bridged via the terminal points, which is why bridging does not provide much added value here.
