Link modules
Feeders can be easily assembled from single devices with the
help of the link modules. The following table shows the different
combination options for devices with screw or spring-type
terminals.

Version not possible
1)
The link modules cannot be used for 3RV2.21-4PA1., 3RV2.21-4FA1.,
3RV2.31-4K.1., 3RV2.31-4R.1., 3RV2.32-4K.1., 3RV2.32-4R.1., 3RV27 and
3RV28 motor starter protectors/circuit breakers.
2)
To assemble the feeder between a motor starter protector and a contactor
in size S3, the 3RA2942-1A00 standard mounting rail adapter must be
used.
3)
A spacer for height compensation on AC contactors, size S0, is optionally
available,
see page 7/49
.
4)
To assemble the feeder between a motor starter protector and a soft starter
in size S2, the 3RA2932-1CA00 standard mounting rail adapter must be
used.
5)
It is only permissible to assemble the feeder between the motor starter
protector and the soft starter in size S3 on a mounting plate.
6)
The motor starter protector to contactor hybrid link modules cannot be
used for the 3RV2.21-4PA1., 3RV2.21-4FA1., 3RV27 and 3RV28 motor
starter protectors/circuit breakers. They are suitable only for constructing
direct-on-line starters.
Note:
•
Link modules can be used in
- Sizes S00 and S0: up to max. 32 A
- Size S2: up to max. 65 A
•
Hybrid link modules can be used in
- Sizes S00 and S0: up to max. 32 A
