PTTB 4 - Double-level terminal block

Double-level terminal block, nom. voltage: 500 V, nominal current: 28 A, connection method: Push-in connection, 1st and 2nd level, Rated cross section: 4 mm2, cross section: 0.2 mm2 - 6 mm2, mounting type: NS 35/7,5, NS 35/15, color: gray

  • In addition to the testing option in the double function shaft, all terminal blocks provide an additional test pick-off
  • The compact design and front connection enable wiring in a confined space
  • The Push-in connection terminal blocks are characterized by the system features of the CLIPLINE complete system and by easy and tool-free wiring of conductors with ferrules or solid conductors
  • Tested for railway applications
