Rated operational current and derating

Values for rated operational current I
Depending on the current setting range, the following rated operational currents apply for the
3RM1 motor starters:
Motor starter version
Rated operational current I
Setting range for I
Minimum current per phase of the motorized
load [A]
Note
The devices with I
10 A in the highest setting level. This setting is intended for resistive loads to 10 A and is not
suitable for operating motors. With this setting, there is no overload trip in accordance with
Class 10A. Instead, this takes place in accordance with the description in the chapter
"Overload protection/device protection characteristic (Page 125)".
As soon as the minimum current limit is violated, fault detection (phase failure) picks up.
When using the 3RM11 Failsafe and 3RM13 Failsafe motor starters, please note that no
neutral conductor may be connected in the load circuit, e.g. in the case of a 230 V brake or
resistive loads.
