Your advantages
Well-known connection principle allows worldwide use
Low temperature rise, thanks to maximum contact force
Allows connection of two conductors
Conductor connection on several levels enables higher contact density
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
