The assignments of the motor currents to the motor powers are recommended values. Due
to the introduction of energy-efficient motors (IE3, IE4) to the market, rated currents are
falling for any given power. At the same time, the start-up currents rise.
NOTICE
Dimensioning instructions
Take the current characteristics of the connected motor and motor starter into account
when dimensioning. The following characteristic values are relevant:
•
Ratio of rated current to motor starting current
•
The maximum starting current of the motor may deviate from the values specified by the
manufacturer by 20% in accordance with EN 60034-1.
•
Maximum permissible current range of the motor starter: The permissible current range
can be found in the graphic in Chapter "Device protection model (Page 95)".
You will find more information on dimensioning switching devices for IE3/IE4 motors in the
