UT 4 - Feed-through terminal block

Feed-through terminal block, nom. voltage: 1000 V, nominal current: 32 A, number of connections: 2, connection method: Screw connection, Rated cross section: 4 mm2, cross section: 0.14 mm2 - 6 mm2, mounting type: NS 35/7,5, NS 35/15, color: gray

  • The large wiring space enables the connection of solid and stranded conductors without ferrules, even above the nominal cross section
  • As well as saving space, the compact design enables user-friendly wiring in a small amount of space
  • Optimum screwdriver guidance through closed screw shafts
  • The cable entry funnel enables the use of conductors with ferrules and plastic collars within the nominal cross section
  • Tested for railway applications
