PTTB 2,5-LA 24 RD - Double-level terminal block

Double-level terminal block, The operating voltage is determined by the LED display version. Key data LED 12 V DC - 30 V DC, 0.7 mA - 2.4 mA, nom. voltage: 500 V, nominal current: 20 A, connection method: Push-in connection, Rated cross section: 2.5 mm2, cross section: 0.14 mm2 - 4 mm2, mounting: NS 35/7,5, NS 35/15, color: gray

  • 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
  • In addition to the testing option in the double function shaft, all terminal blocks provide an additional test pick-off
