XJ01-14 to 20 type auto-coupling step-down starter circuit

XJ01 series autocoupler is suitable for step-down starting of 380V motors with a capacity of 300kW and below. The starter
has protection functions such as overload and voltage loss. The auto-coupling step-down starter is controlled by the time relay to automatically complete the switching on and off
. The starting time (5~120s) is adjustable.
(1) XI01-14~20 type auto-coupling step-down starter starting circuit
    circuit is shown in Figure 3-50. It uses two contactors to switch automatically. In the figure, Hi is the full voltage operation indicator light , H2
is the reduced voltage start indicator light, and H3 is the power indicator light .
