(sizes S00 to S3)

Description
Prerequisite
The following components, which have to be ordered separately, are required to mount the
contactor assembly for star-delta (wye-delta) start:
● Assembly kit for the 3RA24 contactor assembly for star-delta (wye-delta) start
● Function modules with or without communication connection.
● Three power contactors 3RT20
Note
For size S2 / S3, spring-loaded connection only in the control circuit
The
following assemblies for spring-loaded connection are available for sizes S00 and S0
only.
Note
If the function modules are used, they take over the tasks associated with control circuit
wiring and the timing relay. However, an installation without fun
ction modules and with an
additional external timing relay continues to be possible. Accordingly, the scope of supply of
the assembly kit includes the wiring modules for the control circuit wiring (these are not
required if function modules are being used)
