The PSR range is the most compact of all ABB’s softstarter ranges. The compact PSR range makes it possible to fit many devices into the same enclosure.
The setup of the PSR is easily done and confirmed using the three clearly marked potentiometers on the front.
The built-in by-pass on all sizes does not only save energy; it will also ensure the most compact ABB’s softstarter design and reduce the installation time. Thanks to the reduced heat generation, the softstarter can be mounted inside high IP class enclosures.
