Introduction to CC18SA120 Contactors (Electromechanical)
Contactors (electromechanical) are devices used in the electrical industry to control the flow of electrical current. CC18SA120 contactors are particularly designed to meet the requirements of industrial and commercial applications. This article will provide a detailed overview of CC18SA120 contactors’ application field and working principle.

Application Field of CC18SA120 Contactors (Electromechanical)
CC18SA120 contactors are designed to provide exceptional high power switching ability and are ideal for high voltage applications. The contactors are suitable for heavy-duty industrial applications, and can be used for switching control of lighting, air conditioning, motors, pumps, conveyer systems, ovens, and other related equipment. The main advantage of CC18SA120 contactors is their superior durability over traditional contactors in the field, allowing for reliable operation that is often the deciding factor in selecting the contactor for a given application.

Working Principle of CC18SA120 Contactors (Electromechanical)
CC18SA120 contactors use an electric current to actuate the mechanical contacts in order to create a secure electrical connection. The contactor consists of three main components; a coil, an armature, and two contact plates. When an electric current is supplied to the coil, it generates an electromagnetic field (EMF) which is used to actuate the armature. This in turn pushes the contact plates together, forming an electrical connection.

The contact plates are comprised of a metal strip with two contact surfaces which are separated by an insulating material. The contact surfaces are designed in such a way that they make contact with a very small gap between them, reducing the contact resistance. The contact plates are also designed to provide a large contact force, which ensures a reliable electrical connection when the contactor is activated. The contact force is adjustable, allowing the user to set the contact force to a desired level for their specific application.

Conclusion
CC18SA120 contactors are a high-performing, reliable and durable solution for industrial and commercial applications. The contactors utilize an electric current to actuate a mechanical contact, thus providing a secure electrical connection. The contact plates are designed to provide a large contact force and reduce contact resistance, ensuring an efficient and reliable electrical connection every time.
