LesPaul Posts: 467 Rating: (59)	hello auotmation_1, yes ist is correct, you can measure a voltage. A 3RW40 Soft Starter has at the controlled phases L1 and L3 per phase 2 antiparallel switched thyristors inside. The uncontrolled phase L2 is only looped through, without thyristors. In total are 4 thyristors built in. http://support.automation.siemens.com/WW/view/en/26664361 kind regards LesPaul
