General information

General criteria for the selection of devices
The motor starter protectors, contactors, solid-state switching devices, soft starters and
overload relays in the following tables are all specified in their basic versions with screw
terminals, i.e. (in particular) without accessories. Where available, of course, versions with
spring-loaded terminals or ring cable lug connections as well as accessories such as
auxiliary switches, auxiliary trip units etc. can be used.
The contactors listed have a rated control supply voltage
with other voltages can also be used.
The 3RU21 thermal overload relay and the 3RB30 / 3RB31 solid-state overload relays can
be directly mounted onto the contactor. The 3RB22 / 3RB23 solid-state overload relay and
the SIMOCODE pro 3UF7 motor protection and control device are essentially used for stand-
alone installation. In their basic version, these devices are specified with a rated control
supply voltage of 230 V AC.
Mounting the combinations
When mounting the devices, specific arcing spaces must be maintained so that short-circuits
can be cleared safely and reliably. The appropriate installation guidelines can be found in
Section Installation guidelines (Page 91).
The technical data of the individual devices must be taken into account when selecting a
device.
400 V AC / 500 V
The tables below are primarily structured for the 400 V and 500 V line voltages for grounded
networks (at 50 and 60 Hz) generally found in IEC regions. The coordination tables for 690 V
will follow.
Tests are carried out with a test voltage which lies 10% above these values (further details
can be found in the test reports). Thus, the specified combinations can also be used for other
networks as long as their maximum voltage does not exceed the test voltage. This means,
for instance, the combinations for 400 V can also be used for 415 V networks that have a
line supply tolerance of +5%.
