Device terminal blocks PTVFIX device terminal blocks The PTVFIX device terminal blocks are part of the FIX system and use the same accessories as the distribution blocks. The primary difference compared to the distribution blocks is the bridging. While the other FIX block versions feature integrated bridging, multi-blocks do not have any integrated bridging. This means that the terminal blocks are the only blocks in the FIX system that carry multiple potentials in just one block. The blocks are designed such that only two terminal points are ever connected to one another. The PTVFIX device terminal blocks are available with a cross-section of 2.5 mm² with 2, 4, 6, 8, or 10 terminal points, which in turn means 2, 3, 4, or 5 potentials per block. Subsequent manual bridging of the device terminal blocks is not feasible, as the blocks do not have a special function shaft or bridge shaft due to their compact design. G and GE device terminal blocks The G and GE device terminal blocks are not part of the FIX system and use universal screw connection technology. This connection is suitable for wiring 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. As with the PTVFIX device terminal blocks, the terminal points of the G… device terminal blocks are not bridged with each other. The GE 10/2BA BU block is the only exception. The G... device terminal blocks are available in nominal cross-sections of 4 and 10 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.
