Connection cross sections
Connectable cable cross-sections depend on the motor starter's connection system.
Connection system
Order number
Screw connection 3RM1...-1AA.4
Push-in spring-type terminals 3RM1...-2AA.4
Hybrid connection method
Control circuit realized as push-in spring-loaded
terminal and main circuit as screw terminal
3RM1...-3AA.4
The table below contains the suitable conductor cross-sections for the control circuit and
signaling contacts (= auxiliary contacts) and for the main circuit (= main contacts).
