UTTB 2,5-MT-P/P BU - Knife-disconnect terminal block

Knife-disconnect terminal block, With test socket screws for insertion of test plugs, nom. voltage: 400 V, nominal current: 22 A, connection method: Screw connection, Rated cross section: 2.5 mm2, cross section: 0.14 mm2 - 4 mm2, connection method: Screw connection, Rated cross section: 2.5 mm2, cross section: 0.14 mm2 - 4 mm2, mounting: NS 35/7,5, NS 35/15, color: blue

  • For a clear overview, each terminal point supports large-surface labeling
  • Convenient separation of circuits, thanks to lever-type disconnect knife
  • For example, two separate potentials can by routed side by side with the help of bridging between non-adjacent terminal blocks
