ABB Soft Starter Highlights


Reduce the electrical stresses and keep the motor protected with the MMS
The PSR reduces the starting current for the motor. The possibility to connect it
to the manual motor starter makes it possible to build a compact and complete
starting solution with overload and short-circuit protection.


Saving time and money with built-in bypass and easy set-up
On the PSR, the bypass is built in and verified by ABB, saving you time during
installation and space in your panel. Set-up is done through three potentiometers
making it very fast and easy.


Reduce the mechanical stresses on your motor
Soft start and stop with PSR will reduce mechanical wear and tear on the
application and increase the availability and uptime.
