Typy PSR, PSS, PSE, PST a PSTB ... Nejnovějším členem řady softstartérů ABB je optimální softstartér PSE. Tento Softstartér disponuje všemi potřebnými funkcemi pro ochranu motoru i softstartéru. Softstartéry PSE osazeny jazykově neutrálním podsvíceným displejem a 4mi tlačítky. Funkce jsou zobrazovány pomocí ikon, hodnoty a kódy zpráv pomocí 7mi segmentového displeje. V neposlední řadě jsou softstartéry PSE vybaveny zabudovaným by-pass kontaktem.
