Connection Cross Sections - Siemens 340 Manual

9.1.6

Connection cross sections

Connectable cable cross-sections depend on the motor starter's connection system.
Connection system
Screw connection
Push-in spring-type terminals
Hybrid connection method
Control circuit realized as push-in spring-loaded
terminal and main circuit as screw terminal
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).
Type of the connectable
conductor cross-section
for main contacts
•
– solid
– finely stranded
– with conductor end
processing
– without conductor final
cutting
for auxiliary contacts
•
– solid
– finely stranded
– with conductor end
processing
– without conductor final
cutting
for AWG conductors
•
– for main contacts
– for auxiliary contacts
All AWG data applies to solid conductors.
