Your advantages

Since there are two function shafts per level, all potential distribution tasks can be implemented quickly
For a clear overview, each terminal point supports large-surface labeling
As an option, the levels can be connected using the FBS‑PV UT vertical bridge
For example, two separate potentials can by routed side by side with the help of bridging between non-adjacent terminal blocks
Tested for railway applications
