Current ranges
The 3RM1 motor starters are designed for the following rated operational currents of the
loads:
Versions
Adjustable response value current
[A]
Maximum permissible motor power
at 400 V AC [kW]
3RM1.01-..... 0,1 ... 0,5 0,12
3RM1.02-..... 0,4 ... 2 0,75
3RM1.07-.....* 1,6 ... 7 3
* The versions of the 3RM1.07-..... motor starter are also suitable for operating resistive loads (e.g.
heaters) up to a rated operational current of I
AC51
= 10 A.
Control supply voltages
The 3RM1 motor starters are designed for the following control supply voltages:
Versions
Control supply voltage
3RM1...-.AA0. 24 V DC
3RM1...-.AA1. 110 … 230 V AC 50/60 Hz; 110 V DC
Note the following information for the different device versions:
Note
3RM10/3RM12
Standard motor starters
with 24 V DC control supply voltage
The same voltage source (potential) must be used for the control supply voltage and the
control inputs.
The reference point for the control inputs is terminal A2.
Note
3RM10/3RM12 Standard motor starters with 110 to 230 V AC/110 V DC control supply
voltage
The same voltage source (potential) must be used for the control supply voltage and the
control inputs.
The reference point for the control inputs is terminal A2.
When controlling with a PLC, control must be via relay outputs.
There must be no parallel load (e.g. a lamp) connected at the control inputs in the case of
motor starters with the product version E01.
