Control circuit: S0 to S12
Fig. 3-29: Reversing contactor combination for control circuit (frame sizes S0 to S3)
Technical specifications The technical specifications of the contactor combinations for reversing cor-
respond to those of the basic units for the corresponding frame size.
3.3.10 3RT14 Wye-delta combinations
The 3RA1 wye-delta combinations in frame sizes S00 to S3 are available as
follows:
• Fully assembled with the usual auxiliary switches in the following frame
sizes:
- S00-S00-S00
- S0-S0-S0
- S2-S2-S0
- S2-S2-S2
- S3-S3-S2
Frame sizes S2 to S3 are delivered already mounted on a base plate.
• In USA sold only for self-assembly.
• S00 to S12 As a kit for self-assembly.
The same accessories can be used as for the basic units of the correspond-
ing frame size (see Section 3.4, "Contactor accessories").
