Contactors are an electrical relay that can be used to control the flow of electricity in the circuit. Usually, contactors are also called electrical switching devices that turn on and off high voltage circuits and are used more in industrial and commercial applications. Contactors are one of the most widely used equipment in the electrical industry and are designed and produced according to the needs of the market in various sizes, voltages and currents, and in general, the complex structure and reliable performance of contactors make this part a basic and important tool in control. Electric current is converted into power in electrical systems. The contactor consists of three main parts: the coil, the blade and the plastic protector, whose operation is based on the law of electromagnetics.
