JJlB-90~315/660-2 type auto-coupling step-down starter circuit
Source: InternetPublisher:常思一二 Updated: 2011/07/20
The circuit shown in the figure is suitable for three-phase motors with a rated voltage of 660V and a rated power of 90 to 315kW, and is used for auto-coupling step-down starting. The coil voltage of the AC contactor, intermediate relay, and time relay is 220V or 380V, while the working voltage of the indicator light is 360V or 110V, so the control circuit of the starter uses transformer T for power supply.
