  • Well-known connection principle allows worldwide use
  • Low temperature rise, thanks to maximum contact force
  • Allows connection of two conductors
  • Extremely small design for the respective conductor cross section
  • Integrated protective guide prevents incorrect insertion of the conductor underneath the tension sleeve
  • The latching on the side enables various numbers of positions to be combined

Notes

Note on applicationFor safe conductor connection, always adhere to a defined tightening torque. Particularly in the case of PCB terminal blocks with two or three positions, the individual solder pin for each contact point cannot compensate for this. That is why the terminal blocks must be supported during conductor connection (held with one hand, support on the housing).
