For AC SOhz or 60hz, rated insulation voltage of 660V (690V}, use the AC-3 category rated working voltage of 380V, powerof 80KW and the following three phase squirrel cage induction motor for controlling the stator winding by star for access tothe triangular shape to start and stop. After assembling the corresponding specifications of thermal relay can be related to the motor and circuit overload Protection. The starters and QJX4 have the same functionality can be equated with the same specification used interchangeably.
