The contactor is an electrical component whose main function is to control and protect the electrical circuit. It is widely used in various electrical devices, mechanical equipment, automated production lines and other fields. In this article, we will introduce the product description of the contactor, and how to use and apply the contactor in different environments correctly. Product Description The contactor is composed of electromagnetic coil, moving contact, static contact and so on. The electromagnetic coil is the control part of the contactor, which acts as the driving function of the switch, and the two contacts are the connecting part of the contactor, which play the role of conduction and disconnection. The size and electrical parameters of the contactor are different, and they are suitable for different types of electrical control occasions. Usually, the working voltage range of the contactor is AC220V/380V or DC24V. It has the characteristics of strong electrical isolation, sensitive action response, high working reliability, strong anti-interference ability, etc., and can withstand a certain number of switching times (generally more than 200,000 times). Instructions 1. Wiring of the contactor. The wiring of the contactor should be connected correctly according to the identification of the contactor to ensure the smooth flow of the circuit. 2. Installation of the contactor. The contactor should be installed at a certain distance from other components to avoid mutual interference. The contactor needs to be installed in a dry, ventilated, and dust-less environment to ensure its normal operation. 3. Operation of the contactor. When using a contactor, attention should be paid to its rated voltage and current range to avoid overloading. When opening and closing the contactor, it is necessary to determine whether its control signal source is normal and use it together. use environment Contactors in different environments have different characteristics and application ranges. In the environment that can withstand high temperature and harsh environment, the suitable high temperature contactor should be selected. In special environments such as high altitude, low temperature, and humidity, it is necessary to choose a contactor that can adapt to the special environment. In hazardous locations, it is necessary to use explosion-proof contactors that are explosion-proof and resistant to interfering corrosive substances. In the use of different electrical control systems, it is also necessary to select different types of contactors to meet the control requirements of different needs.
