Siemens SIRIUS 3RW55 - Selection of the Soft Starter Using the Simulation Tool for Soft Starters; Structure of the Article Number

3.9 Selection of the soft starter using the Simulation Tool for Soft
Starters
The soft starter can be con󹪝gured with the STS (Simulation Tool for Soft Starters) software. The
STS suggests suitable soft starters for the respective application based on the entered motor and
load data and application requirements, as well as providing information on the
parameterization.
You can download the Simulation Tool for Soft Starters (STS) for free on the 3RW5 topic page

Information on the rated operational current (derating)
Note that the 3RW55 and 3RW55 Failsafe soft starters are approved for operation in a
temperature range of -25 °C to +60 °C. Consider the derating of the rated operational current at
ambient temperatures higher than 40 °C. You will 󹪝nd further information on derating in
the Technical speci󹪝cations (Page 285) in section "Power electronics" or in Catalog IC 10 (https://
support.industry.siemens.com/cs/ww/en/view/109747945).
