10.1 J 205/J 405 three phase Direct Start D.O.L. with contactor (6-leads stator)
The stators are wound for different voltages/frequencies and can be Delta- or Star-connected. For example
stator 400/690V 50Hz is Delta-connected for 400V duty. The contactor is activated by the same voltage as the
supply voltage. Therefore, when changing from one voltage to another the contactor must also be changed.
