•
Compact dimensions.
12 - 25 Arms in 45 mm wide
housing, 32 - 55 Arms in 75 mm wide housing, 70 - 90
Arms in 120 mm wide housing.
•
Integrated protection.
Diagnostic functions provide
additional protection. RSWT is also equipped with an
overload protection (Class 10).
•
Three phase controlled.
•
Guided model selection.
Easy to use selection tool to

Description
RSWT is an extremely compact and easy to use
3-phase soft starter for AC pumps and ventilators
rated up to 90 Arms.
The starting parameters can be easily set-up
through 3 knobs.
The integrated motor overload protection (Class
10) results in a higher installation flexibility.
Applications
RSWT soft starters are the ideal solution for 3-phase fixed speed AC pumps and ventilators where there is the
need to reduce the starting current and/or minimise stresses on the motor during start and stop.
The RSWT offers a number of integrated diagnostic functions that can replace additional components inside
the electrical panel.
Typical applications include: pumps and fans.
Main functions
•
Soft starting and soft stopping of pumps and ventilators.
•
Integrated electronic overload protection (Class 10).

Note: For Trip class 20 applications we recommend the use of an external overload protection due to the
higher FLC setting that is required on RSWT. The FLC setting for Class 20 applications needs to be set to a
higher value with respect to the motor FLC in order not to trip the electronic motor overload protection available
on the RSWT soft starters.
