The Star-Delta circuit is one of the most common circuits used to start a motor. It can be confusing to wire up the circuit from just the circuit diagram. Here we have mapped them out to the real components and provide a step by step guide to wiring a simple star-delta circuit.
In choosing the correct contactor, you will need to consider the load type that the contactor will be used with. Special consideration for the 3 phase Squirrel-cage inductive motor load, which is one of the most common load types in the industry, where the motor draws a significant amount of current (inrush current) when
