The article provides information on motor control circuits. It is mentioned that two types of commonly used control circuits are 2-wire control circuit and 3-wire control circuit. The 2-wire circuits provide automatic control and maintained contact devices are used to regulate magnetic motor starter. The 3-wire control circuits helps in manual control and momentary contact devices are used to regulate motor starter. Information on different types of 3-wire control circuits is also presented.
