UTTB 2,5 - Double-level terminal block
Double-level terminal block, nom. voltage: 500 V, nominal current: 24 A, connection method: Screw connection, Rated cross section: 2.5 mm2, cross section: 0.14 mm2 - 4 mm2, mounting type: NS 35/7,5, NS 35/15, color: gray
- 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
