About products: 

The PSR softstarter is the most compact of all the softstarter ranges, thereby making it possible to design compact starting equipments. The system concept with Manual Motor Starters and the PSR provides a far more compact starting solution than for instance a star delta starter. Built-in by-pass reduces the energy loss and makes the connection easier and with only three potentiometers, the set-up couldn’t be any easier. Still, the optimized ramping characteristics will ensure a very smooth start and stop for all applications.
