PTTB 2,5-2R/NAMUR - Component terminal block

Component terminal block, connection method: Push-in connection, 1st and 2nd level, Rated cross section: 2.5 mm2, cross section: 0.14 mm2 - 4 mm2, mounting type: NS 35/7,5, NS 35/15, color: gray

  • 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
  • The compact design and front connection enable wiring in a confined space
  • In addition to the testing option in the double function shaft, all terminal blocks provide an additional test pick-off
