Load type
Here, you can specify whether the motor starter must protect a single-phase or a three-
phase load.
● Asymmetry detection is deactivated in the case of a single-phase load, such as a single-
phase AC motor!
The single-phase load can be connected between any two paths of the motor starter for
all mechanically switched motor starters.
● Asymmetry detection is activated for three-phase loads such as three-phase
asynchronous motors. The three phase currents are compared to one another.
Note
The load type is only relevant for mechanical motor starters. Only 3-phase load types
may be connected to electronic starters.
Note
Only one motor
must be connected to a motor starter, otherwise motor protection can no
longer be guaranteed.

Protection against voltage failure
You use this device parameter to specify whether or not the overload message must be
retained after an electronics voltage failure:
● Overload
● No overload
