IntroductionThe 7-1618387-2 is an electromechanical contactor, a very important, versatile and indispensable switch used in many industries. A contactor is an electrically-operated switch used for switching an electrical power circuit. It is typically used for controlling motors, heating elements, or other circuits requiring the control of large amounts of electric current. It is essentially a large relay, with contacts rated to handle the load current of the circuit.ConstructionMost of contactors consist of an open/closed case or housing, a coil, one or more movable contacts, auxiliaries such as auxiliary contacts, and manual/automatic operating mechanisms. In 7-1618387-2 contactors, the coil is used to generate the magnetic field necessary to operate the contacts. When the coil is energized, an electromagnet is created, which generates a magnetic field. This magnetic field attracts the contactor’s movable contacts and closes the electrical circuit.Application The applications of 7-1618387-2 contactors in industries include motor control, lighting control, power distribution, process control, electrical protection and other industrial automation applications. These contactors can be used for motor switching, providing the best combination of convenience, safety and efficiency. They are also often used to switch on or off high power loads, such as electric motors or heating elements. Additionally, these contactors offer the advantages of separate control and power components, allowing the use of less expensive components and smaller equipment spaces.Working PrincipleThe working principle of 7-1618387-2 contactors is simple yet effective. It works by using electrically powered electromagnetic coils, which are used to attract the contactor’s movable contacts. When the power supply to the coil is turned on, it creates a magnetic field which attracts the contact closes the electrical circuit. When the coil is turned off, it releases the contact, opening the electrical circuit. As the contact is opened or closed, it makes an audible sound, often used to indicate the status of the circuit.Advantages of Contactors Contactors offer a range of unique advantages over conventional switching devices, making them an ideal choice for many industrial and commercial applications. They are cost-effective and reliable, and offer a high level of mechanical and electrical reliability. They also require a lower current rating than contact relays, reducing the burden on the power supply. Additionally, they are designed to minimize contact wear and to provide protection against overloads.ConclusionContactors are an important, versatile, and indispensable switch used in many industries, and the 7-1618387-2 contactors offer a unique set of advantages. They are cost-effective and reliable, and provide the best combination of convenience, safety and efficiency. They are used in a wide range of applications, from motor control to electrical protection, and their working principle is simple yet effective.
