UTTB 4 WH - Double-level terminal block

Double-level terminal block, nom. voltage: 800 V, nominal current: 30 A, connection method: Screw connection, 1st and 2nd level, Rated cross section: 4 mm2, cross section: 0.14 mm2 - 6 mm2, mounting type: NS 35/7,5, NS 35/15, color: white

  • 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
