Current ranges
The table below shows the switchable motor powers depending on the primary voltage,
according to DIN EN 60947-4-1: Table G.1. The stated current ranges are valid for the
ET 200SP motor starters.
0.1 ... 0.4 A
0.1 A
230 V AC < 0.06 kW 0.09 kW < 0.06 kW 0.18 kW
400 V AC < 0.06 kW 0.12 kW < 0.09 kW 0.25 kW
500 V AC < 0.06 kW 0.18 kW < 0.12 kW 0.37 kW
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
• Maximum permissible current range of the motor starter: The permissible current range
You will find more information on dimensioning switching devices for IE3/IE4 motors in the
Switching devices application manual
(http://support.automation.siemens.com/WW/view/en/94770820).
