Requirements
● You are in menu "Monitoring > Measured Values".
Procedure
Select a measuring value.
The menus "Phase Currents [%]" and "Phase Currents (rms)" contain further menu items,
which you can switch to with "OK".

Explanation
Phase currents [%]
• IL1
• IL2
• IL3
• Average
The phase currents are displayed as a percentage. You can monitor
each phase (L1/L2/L3) individually, or the average of all 3 phases.
Phase currents (r.m.s.) [A] The phase currents are displayed in amperes. You can monitor each
phase (L1/L2/L3) individually, or the average of all 3 phases.
Motor temperature rise [%] Current value of motor temperature rise in %. This value shows the
relative temperature rise of the motor.
Remaining motor cooling time [s] Remaining recovery time (minimum cooling time of motor) still to be
observed following activation of motor overload protection until the
3RW52 soft starter is once again ready for operation.
Remaining contact block cooling time [s] The remaining cooling time of the contact block is dependent on the
thermal capacity of the power unit and the ambient conditions
(temperature, air circulation, installation location etc.)
Contact block heating [°C] The currently calculated contact block temperature rise is
continuously compared with the previously stored contact block
temperature rise.
