3RT1/3RH1 contactors
Two-conductor connec-
tion
Conductor cross-sec-
tions
3-90
It is possible with all the main, auxiliary, and control cable connections to
connect two conductor ends. They can also be used to connect untreated
conductors with different cross-sections. Box terminals each with 2 terminal
points are provided for the main conductor connection in contactors of
frame sizes S2 and S3.
This connection method also promises problem-free looping and parallel
connection without intermediate terminals.
Permissible conductor cross-sections for main and auxiliary connections:
